  using System.Configuration;
  using System.Data;
  using System.Linq;
  using System.Web;
  using System.Web.Security;
  using System.Web.UI;

  using System.Web.UI.WebControls.WebParts;
  using System.Xml.Linq;
  using System.Data.sqlClient;

      public partial class WebForm1 : System.Web.UI.Page
      {
          protected void Page_Load(object sender,EventArgs e)
          {

          }

          protected void Button1_Click(object sender,EventArgs e)

                  cmd.Parameters.AddWithValue("@Amount",TextBox8.Text);
                  cmd.Parameters.AddWithValue("@Total",TextBox9.Text);
                  da.SelectCommand = cmd;
                  try
                  {
                      da.Fill(ds);
                  }
                  catch (Exception ex)
                  {
                      string strErrMsg = ex.Message;
                      //throw new applicationException("!!!! An error an occured while
                      //inserting record."+ex.Message)
                  }
                  finally
                  {
                      da.dispose();
                      cmd.dispose();
                      cnn.Close();
                      cnn.dispose();
                  }
                  if (ds.Tables[0].Rows.Count > 0)
                  {
                      Msg.Text = "Photo setting sucessfullY";
                  }
                  else
                  {
                      Msg.Text = "photosetting failled";
                  }
              }
          }
      }
  }

MY ERROR
image are not insert how to change in my code pls send me code
How to rectify.

我的存储过程,

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
 GO

ALTER PROCEDURE [dbo].[photoset]
(
    @BillNo Numeric,@CustomerName varchar(300),@Address nvarchar(300),@StartDate datetime,@EndDate datetime,@Systemurl varchar,@Numberofcopies numeric,@Amount numeric,@Total numeric
)

AS
BEGIN
    insert into tblphotosetting
    (
      BillNo,CustomerName,Address,StartDate,EndDate,Systemurl,Numberofcopies,Amount,Total
    )
    values
    (
      @BillNo,@CustomerName,@Address,@StartDate,@EndDate,@Systemurl,@Numberofcopies,@Amount,@Total
    )
END

解决方法

在IF条件之前添加一个条件,以检查数据集中是否有任何表.如果存储过程没有返回任何表,这将避免错误.
if(ds.Tables.Count > 0)
{ 
   if (ds.Tables[0].Rows.Count > 0)
   {
      Msg.Text = "Photo setting sucessfullY";
   }
   else
   {
      Msg.Text = "photosetting failled";
   }
}

编辑 –

看到存储过程后,只有一个insert语句.除非您编写一些select语句以在存储过程中获得一些结果集,否则您无法用表填充数据集.
