使用foreach将gridview数据插入到sql数据库中

如何解决使用foreach将gridview数据插入到sql数据库中

| 我有一个客户端gridview数据，我想将gridview数据插入sql数据库。 首先，我将数据从excel导入到gridview，现在我想将其插入到sql数据库中。 我使用foreach循环一一插入记录。但是foreach循环只选择第一条记录，而我不能增加行索引。我怎样才能做到这一点？并选择其他记录？

protected void btnInsertIntoDatabase_Click(object sender,EventArgs e)
    {
    A:
        string Name = string.Empty;
        string CarType = string.Empty;
        string TechnicalNo = string.Empty;
        string ProductionDate = string.Empty;
        string EngaineType = string.Empty;
        string NoInStock = string.Empty;
        string NoForCar = string.Empty;
        string Price = string.Empty;
        string Image = string.Empty;
        string Desc = string.Empty;
        string PartType = string.Empty;
        string Level = string.Empty;
        string Unit = string.Empty;
        string Ratio = string.Empty;
        string Dirham = string.Empty;
        string ExtraMoney = string.Empty;

        int GVCount = GridView1.Rows.Count;

        foreach (GridViewRow GVRow in GridView1.Rows)
        {
            Name = GVRow.Cells[1].Text;
            CarType = GVRow.Cells[2].Text;
            TechnicalNo = GVRow.Cells[3].Text;
            ProductionDate = GVRow.Cells[4].Text;
            EngaineType = GVRow.Cells[5].Text;
            NoInStock = GVRow.Cells[6].Text;
            NoForCar = GVRow.Cells[7].Text;
            Price = GVRow.Cells[8].Text;
            Image = GVRow.Cells[9].Text;
            Desc = GVRow.Cells[10].Text;
            PartType = GVRow.Cells[11].Text;
            Level = GVRow.Cells[12].Text;
            Unit = GVRow.Cells[13].Text;
            Ratio = GVRow.Cells[14].Text;
            Dirham = GVRow.Cells[15].Text;
            ExtraMoney = GVRow.Cells[16].Text;
            break;
        }

        sqlConnection scn = new sqlConnection(clspublic.GetConnectionString());
        sqlCommand scm = new sqlCommand();
        scm.Connection = scn;
        scm.CommandText = @\"INSERT INTO tblProduct
                          (fName,fxCarType,fProductionDate,fEngineType,fNoinStock,fNoforCar,fPrice,fRatio,fDirham,fExtraMoney,fImage,fDesc,fxPartType,fxLevel,fUnitType,fTechnicalNo)
               VALUES     (@fName,@fxCarType,@fProductionDate,@fEngineType,@fNoinStock,@fNoforCar,@fPrice,@fRatio,@fDirham,@fExtraMoney,@fImage,@fDesc,@fxPartType,@fxLevel,@fUnitType,@fTechnicalNo)\";

        scm.Parameters.AddWithValue(\"@fName\",Name.ToString());
        scm.Parameters.AddWithValue(\"@fxCarType\",CarType.ToString());
        scm.Parameters.AddWithValue(\"@fTechnicalNo\",TechnicalNo.ToString());
        scm.Parameters.AddWithValue(\"@fProductionDate\",ProductionDate.ToString());

        scm.Parameters.AddWithValue(\"@fUnitType\",Unit.ToString());
        scm.Parameters.AddWithValue(\"@fxLevel\",Level.ToString());

        goto A;
    } 

    

解决方法

        它之所以成为第一条记录，只是因为您的foreach循环中写有

break

... 以下是适合您的代码

    foreach (GridViewRow GVRow in GridView1.Rows)
    {
        Name = GVRow.Cells[1].Text;
        CarType = GVRow.Cells[2].Text;
        TechnicalNo = GVRow.Cells[3].Text;
        ProductionDate = GVRow.Cells[4].Text;
        EngaineType = GVRow.Cells[5].Text;
        NoInStock = GVRow.Cells[6].Text;
        NoForCar = GVRow.Cells[7].Text;
        Price = GVRow.Cells[8].Text;
        Image = GVRow.Cells[9].Text;
        Desc = GVRow.Cells[10].Text;
        PartType = GVRow.Cells[11].Text;
        Level = GVRow.Cells[12].Text;
        Unit = GVRow.Cells[13].Text;
        Ratio = GVRow.Cells[14].Text;
        Dirham = GVRow.Cells[15].Text;
        ExtraMoney = GVRow.Cells[16].Text;


    SqlConnection scn = new SqlConnection(clspublic.GetConnectionString());
 using(con)
 {  
    SqlCommand scm = new SqlCommand();
    scm.Connection = scn;
    scm.CommandText = @\"INSERT INTO tblProduct
                      (fName,fxCarType,fProductionDate,fEngineType,fNoinStock,fNoforCar,fPrice,fRatio,fDirham,fExtraMoney,fImage,fDesc,fxPartType,fxLevel,fUnitType,fTechnicalNo)
           VALUES     (@fName,@fxCarType,@fProductionDate,@fEngineType,@fNoinStock,@fNoforCar,@fPrice,@fRatio,@fDirham,@fExtraMoney,@fImage,@fDesc,@fxPartType,@fxLevel,@fUnitType,@fTechnicalNo)\";

    scm.Parameters.AddWithValue(\"@fName\",Name.ToString());
    scm.Parameters.AddWithValue(\"@fxCarType\",CarType.ToString());
    scm.Parameters.AddWithValue(\"@fTechnicalNo\",TechnicalNo.ToString());
    scm.Parameters.AddWithValue(\"@fProductionDate\",ProductionDate.ToString());
    scm.Parameters.AddWithValue(\"@fEngineType\",EngaineType.ToString());
    scm.Parameters.AddWithValue(\"@fNoinStock\",NoInStock.ToString());
    scm.Parameters.AddWithValue(\"@fNoforCar\",NoForCar.ToString());
    scm.Parameters.AddWithValue(\"@fPrice\",Price.ToString());
    scm.Parameters.AddWithValue(\"@fRatio\",Ratio.ToString());
    scm.Parameters.AddWithValue(\"@fDirham\",Dirham.ToString());
    scm.Parameters.AddWithValue(\"@fExtraMoney\",ExtraMoney.ToString());
    scm.Parameters.AddWithValue(\"@fImage\",Image.ToString());
    scm.Parameters.AddWithValue(\"@fDesc\",Desc.ToString());
    scm.Parameters.AddWithValue(\"@fxPartType\",PartType.ToString());
    scm.Parameters.AddWithValue(\"@fUnitType\",Unit.ToString());
    scm.Parameters.AddWithValue(\"@fxLevel\",Level.ToString());

   scm.ExecuteNonQuery();
 }

}     ,        哇，后藤... 好吧，您在获得第一条记录后就不敢再做任何事了。然后，您从第一个开始再次开始学习。     ,        

 using (SqlConnection scn = new SqlConnection(clspublic.GetConnectionString()))
        {

            foreach (GridViewRow GVRow in GridView1.Rows)
            {
                Name = GVRow.Cells[1].Text;
                CarType = GVRow.Cells[2].Text;
                TechnicalNo = GVRow.Cells[3].Text;
                ProductionDate = GVRow.Cells[4].Text;
                EngaineType = GVRow.Cells[5].Text;
                NoInStock = GVRow.Cells[6].Text;
                NoForCar = GVRow.Cells[7].Text;
                Price = GVRow.Cells[8].Text;
                Image = GVRow.Cells[9].Text;
                Desc = GVRow.Cells[10].Text;
                PartType = GVRow.Cells[11].Text;
                Level = GVRow.Cells[12].Text;
                Unit = GVRow.Cells[13].Text;
                Ratio = GVRow.Cells[14].Text;
                Dirham = GVRow.Cells[15].Text;
                ExtraMoney = GVRow.Cells[16].Text;

                using (SqlCommand scm = scn.CreateCommand())
                {

                    scm.CommandText = @\"INSERT INTO tblProduct
                  (fName,fTechnicalNo)
       VALUES     (@fName,@fTechnicalNo)\";

                    scm.Parameters.AddWithValue(\"@fName\",Name.ToString());
                    scm.Parameters.AddWithValue(\"@fxCarType\",CarType.ToString());
                    scm.Parameters.AddWithValue(\"@fTechnicalNo\",TechnicalNo.ToString());
                    scm.Parameters.AddWithValue(\"@fProductionDate\",ProductionDate.ToString());
                    scm.Parameters.AddWithValue(\"@fEngineType\",EngaineType.ToString());
                    scm.Parameters.AddWithValue(\"@fNoinStock\",NoInStock.ToString());
                    scm.Parameters.AddWithValue(\"@fNoforCar\",NoForCar.ToString());
                    scm.Parameters.AddWithValue(\"@fPrice\",Price.ToString());
                    scm.Parameters.AddWithValue(\"@fRatio\",Ratio.ToString());
                    scm.Parameters.AddWithValue(\"@fDirham\",Dirham.ToString());
                    scm.Parameters.AddWithValue(\"@fExtraMoney\",ExtraMoney.ToString());
                    scm.Parameters.AddWithValue(\"@fImage\",Image.ToString());
                    scm.Parameters.AddWithValue(\"@fDesc\",Desc.ToString());
                    scm.Parameters.AddWithValue(\"@fxPartType\",PartType.ToString());
                    scm.Parameters.AddWithValue(\"@fUnitType\",Unit.ToString());
                    scm.Parameters.AddWithValue(\"@fxLevel\",Level.ToString());

                    scm.ExecuteNonQuery();
                }
            }
        }

    ,        这样尝试， 如果所有控件都带有标签

foreach (GridViewRow GVRow in GridView1.Rows)
    {

  Label lbl = (Label)GVRow.FindControl(\"labelID\");

  string data=lbl.Text;

}

    ,        

using (SqlConnection scn = new SqlConnection(clspublic.GetConnectionString()))
    {

        foreach (GridViewRow GVRow in GridView1.Rows)
        {
            Name = GVRow.Cells[1].Text;
            CarType = GVRow.Cells[2].Text;
            TechnicalNo = GVRow.Cells[3].Text;
            ProductionDate = GVRow.Cells[4].Text;
            EngaineType = GVRow.Cells[5].Text;
            NoInStock = GVRow.Cells[6].Text;
            NoForCar = GVRow.Cells[7].Text;
            Price = GVRow.Cells[8].Text;
            Image = GVRow.Cells[9].Text;
            Desc = GVRow.Cells[10].Text;
            PartType = GVRow.Cells[11].Text;
            Level = GVRow.Cells[12].Text;
            Unit = GVRow.Cells[13].Text;
            Ratio = GVRow.Cells[14].Text;
            Dirham = GVRow.Cells[15].Text;
            ExtraMoney = GVRow.Cells[16].Text;

            using (SqlCommand scm = scn.CreateCommand())
            {

                scm.CommandText = @\"INSERT INTO tblProduct
              (fName,fTechnicalNo)
   VALUES     (@fName,@fTechnicalNo)\";

                scm.Parameters.AddWithValue(\"@fName\",Name.ToString());
                scm.Parameters.AddWithValue(\"@fxCarType\",CarType.ToString());
                scm.Parameters.AddWithValue(\"@fTechnicalNo\",TechnicalNo.ToString());
                scm.Parameters.AddWithValue(\"@fProductionDate\",ProductionDate.ToString());

                scm.Parameters.AddWithValue(\"@fNoinStock\",NoInStock.ToString());
                scm.Parameters.AddWithValue(\"@fNoforCar\",NoForCar.ToString());
                scm.Parameters.AddWithValue(\"@fPrice\",Price.ToString());
                scm.Parameters.AddWithValue(\"@fRatio\",Ratio.ToString());
                scm.Parameters.AddWithValue(\"@fDirham\",Dirham.ToString());
                scm.Parameters.AddWithValue(\"@fExtraMoney\",ExtraMoney.ToString());
                scm.Parameters.AddWithValue(\"@fImage\",Image.ToString());
                scm.Parameters.AddWithValue(\"@fDesc\",Desc.ToString());

                scm.Parameters.AddWithValue(\"@fUnitType\",Unit.ToString());
                scm.Parameters.AddWithValue(\"@fxLevel\",Level.ToString());

                scm.ExecuteNonQuery();
            }
        }
    }
