C# 使用OLEDB将excel文件加载到Sql时出错

这对我来说绝对不熟悉。我正在尝试使用以下方法加载excel文件：

protected void Button2_Click(object sender, EventArgs e)
{
    try
    {
        if (FileUpload2.HasFile)
        {
            string path = string.Concat((Server.MapPath("~/members/temp/" + FileUpload2.FileName)));
            FileUpload1.PostedFile.SaveAs(path);
           // OleDbConnection OleDbcon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;");
            OleDbConnection OleDbcon = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0 Xml;HDR=YES;");
            OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", OleDbcon);
            OleDbDataAdapter objAdapter1 = new OleDbDataAdapter(cmd);

            OleDbcon.Open();
            DbDataReader dr = cmd.ExecuteReader();

            string con_str = ConfigurationManager.ConnectionStrings["BOMConnectionString"].ConnectionString;

            // Bulk Copy to SQL Server 
            SqlBulkCopy bulkInsert = new SqlBulkCopy(con_str);
            bulkInsert.DestinationTableName = "Table_xxc";
            bulkInsert.WriteToServer(dr);
            OleDbcon.Close();
            Array.ForEach(Directory.GetFiles((Server.MapPath("~/members/temp/"))), File.Delete);
            Label2.ForeColor = Color.Green;
            Label2.Text = "successfully inserted";

        }
        else
        {
            Label2.ForeColor = Color.Red;
            Label2.Text = "Please select the File";
        }
    }
    catch (Exception ex )
    {

        Response.Write("<script>alert(\"An error occurred. The file cannot be loaded to the DB. Check your formats in the excel file.\")</script>"); Response.Write("<script>alert(\"An error occurred. The file cannot be loaded to the DB. Check your formats in the excel file.\")</script>");
    }
}

如果我使用SQLServerManagementStudio中的导入/导出功能，它可以正常工作。如果使用上述代码段，我会在OleDbcon.Open行中出错。 Thai是堆栈跟踪：

in System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)

in System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)
in System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

excel文件是excel 2007中的xml，但我也尝试了excel 2010，正如您在我的代码中看到的，我使用了相应的OLEDB驱动程序。我总是得到外部表不是预期的格式。

我需要一些帮助来解决这个问题。上述代码/格式是否有任何错误？

如果出现异常，为什么不在问题中包含完整的细节，并指出它们出现在哪行？@DanielKelley，对此丹尼尔表示抱歉。我已经修改了问题并添加了详细信息。这个问题可能会有所帮助-@DanielKelley，谢谢。有趣的材料。我在找的时候没有找到它。“我会设法从中得到一些东西。”丹尼尔凯利，没有。尝试了好几种方法，但没有成功！
