如何从数据网格中复制所有值？

Question

我必须将数据网格值导出到Excel。我使用以下代码来复制datagrid值。

InvoiceDataGrid.SelectAllCells()
InvoiceDataGrid.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader
ApplicationCommands.Copy.Execute(Nothing, Me.InvoiceDataGrid)
Dim result1 As String = Clipboard.GetData(DataFormats.Text)
InvoiceDataGrid.UnselectAllCells()

但有时它不会从网格中获取整数值。请帮我。 。

这是我在C＃中编写和使用的东西......

ExportToExcel

private void ExportToExcel()
{
    try
    {
        dataGrid.SelectAllCells();
        dataGrid.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader;
        ApplicationCommands.Copy.Execute(null, dataGrid);
        var resultat = (string)Clipboard.GetData(DataFormats.CommaSeparatedValue);
        var result = (string)Clipboard.GetData(DataFormats.Text);
        dataGrid.UnselectAllCells();
        var path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
        var excelFile = new StreamWriter(@"C:\Users\"+Environment.UserName+@"\Desktop\exportedcompanies.xls");
        excelFile.WriteLine(result.Replace(',', ' '));
        excelFile.Close();           
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}
