Question

我正在从Excel工作表导入数据，但它适用于一个工作表，但不适用于具有相同列和正确数据的另一个工作表。它适用于许多文件但不是很少。我已经将代码附加了下面的示例和错误。在绑定时，它会抛出错误。

正在运作的工作表：

和导致错误的工作表：

错误：

DataBinding：＆＃39; System.Data.DataRowView＆＃39;不包含名称为＆＃39; Amount＆＃39;

代码：

private void ImportDataToGrid(string FilePath, string Extension, string isHDR)
    {
        string conStr = "";
        switch (Extension)

            case ".xls": //Excel 97-03
                conStr = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;
                break;
            case ".xlsx": //Excel 07
                conStr = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;

        OleDbDataAdapter oda = new OleDbDataAdapter();

        string SheetName = dtExcelSchema.Rows[0]["TABLE_NAME"].ToString();
        connExcel.Close();

        //Read Data from First Sheet
        connExcel.Open();
        cmdExcel.CommandText = "SELECT * From [" + SheetName + "]";
        oda.SelectCommand = cmdExcel;
        oda.Fill(dt);

        dc = new DataColumn("WorkNo", typeof(string));
        dc.DefaultValue = txtWorkNo.Text.ToString();

在这些情况下，问题通常是由列名称中有空格（）引起的。

我建议检查一下，并删除那里的任何空格。

为什么选择DataBinding：＆＃39; System.Data.DataRowView＆＃39;不包含名称为＆＃39; xxx＆＃39 ;?的属性
