c# – 将Excel导入Datagridview

我正在使用此代码打开excel文件并将其保存在DataGridView中：

string name = "Items";
string constr = "Provider = Microsoft.Jet.OLEDB.4.0; Data Source=" + Dialog_Excel.FileName.ToString() + "; Extented Properties =\"Excel 8.0; HDR=Yes;\";";
OleDbConnection con = new OleDbConnection(constr);
OleDbDataAdapter sda = new OleDbDataAdapter("Select * From [" + name + "$]",con);
DataTable data = new DataTable();
sda.Fill(data);
grid_items.DataSource = data;

但是我收到了ISAM错误.有什么建议吗？

解决方法

由于您没有回复我上面的评论,我正在为两者发布解决方案.

您在扩展属性中缺少’

对于Excel 2003试试这个(经过试验和测试)

private void button1_Click(object sender,EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]",con);
        con.open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

顺便说一下,我很久以前就不再使用Jet了.我现在使用ACE.

private void button1_Click(object sender,EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]",con);
        con.open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

对于Excel 2007

private void button1_Click(object sender,EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xlsx" + 
                        ";Extended Properties='Excel 12.0 XML;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]",con);
        con.open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }
