旧格式或无效类型库。 （HRESULT的异常：0x80028018（TYPE_E_INVDATAREAD）） [英] Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))

问题描述

错误（旧格式或无效的类型库（来自HRESULT的异常：0x80028018（TYPE_E_INVDATAREAD）））

此行：

  Microsoft.Office.Interop.Excel._Workbook工作簿= app.Workbooks.Add（Type.Missing）; 
  

如何解决这个问题？

我的完整代码：

  private void button1_Click（object sender，EventArgs e）
 {
 System。 Globalization.CultureInfo oldCI = System.Threading.Thread.CurrentThread.CurrentCulture; 
 System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo（en-US）; 
 
 //创建Excel应用程序
 Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application（）; 
 System.Threading.Thread.CurrentThread.CurrentCulture = oldCI; 
 
 //在Excel应用程序中创建新的WorkBook 
 Microsoft.Office.Interop.Excel._Workbook工作簿= app.Workbooks.Add（Type.Missing）; 
 
 //在工作簿中创建新的Excel工作表
 Microsoft.Office.Interop.Excel._Worksheet worksheet = null; 
 
 //查看程序后的Excel表
 // Funny 
 app.Visible = true; 
 
 //获取第一张表的参考。默认名称为Sheet1。 
 //存储其对工作表的引用
 try 
 {
 //修正：（Microsoft.Office.Interop.Excel.Worksheet）
工作表=（Microsoft.Office .Interop.Excel.Worksheet）workbook.Sheets [ Sheet 1中]; 
工作表=（Microsoft.Office.Interop.Excel.Worksheet）工作簿.ActiveSheet; 
 
 //更改活动工作表的名称
 worksheet.Name =从Ketoan导出; 
 
 //在Excel 
中存储头部分（int i = 1; i< DGData.Columns.Count + 1; i ++）
 {
工作表。单元格[1，i] = DGData.Columns [i  -  1] .HeaderText; 
} 
 
 //将每行和列值存储到Excel表
 for（int i = 0; i< DGData.Rows.Count  -  1; i ++）
 {
 for（int j = 0; j< DGData.Columns.Count; j ++）
 {
工作表Cells [i + 2，j + 1] = DGData.Rows [I] .Cells [j]的.Value.ToString（）; 
} 
} 
 
 //保存应用程序
 string fileName = String.Empty; 
 SaveFileDialog saveFileExcel = new SaveFileDialog（）; 
 
 saveFileExcel.Filter =Excel files | * .xls |所有文件（*。*）| *。*; 
 saveFileExcel.FilterIndex = 2; 
 saveFileExcel.RestoreDirectory = true; 
 
 if（saveFileExcel.ShowDialog（）== DialogResult.OK）
 {
 fileName = saveFileExcel.FileName; 
 
 //固定旧代码：11 para-> add 1：Type.Missing 
 workbook.SaveAs（fileName，Type.Missing，Type.Missing，Type.Missing，Type。缺少，Type.Missing，Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive，Type.Missing，Type.Missing，Type.Missing，Type.Missing，Type.Missing）; 
} 
 else 
 return; 
 
 //退出应用程序
 //app.Quit（）; 
} 
 catch（System.Exception ex）
 {
 
} 
 finally 
 {
 app.Quit（）; 
 workbook = null; 
 app = null; 
} 
} 
  

解决方案

：

  System.Threading.Thread.CurrentThread.CurrentCulture = oldCI; 
  

删除此行或移动到关闭Excel应用程序的行下。

它适用于我。

The error appeared when exporting data in a datagrid view to an Excel sheet:

error (Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD)))

on this line:

Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);

How do I fix this problem?

My full code:

private void button1_Click(object sender, EventArgs e)
{
    System.Globalization.CultureInfo oldCI = System.Threading.Thread.CurrentThread.CurrentCulture;
    System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

    // Creating Excel Application
    Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
    System.Threading.Thread.CurrentThread.CurrentCulture = oldCI;

    // Creating new WorkBook within Excel application
    Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);

    // Creating new Excel sheet in workbook
    Microsoft.Office.Interop.Excel._Worksheet worksheet = null;

    // See the Excel sheet behind the program
    //Funny
    app.Visible = true;

    // Get the reference of first sheet. By default its name is Sheet1.
    // Store its reference to worksheet
    try
    {
        // Fixed:(Microsoft.Office.Interop.Excel.Worksheet)
        worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets["Sheet1"];
        worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.ActiveSheet;

        // Changing the name of active sheet
        worksheet.Name = "Exported from Ketoan";

        // Storing header part in Excel
        for (int i = 1; i < DGData.Columns.Count + 1; i++)
        {
            worksheet.Cells[1, i] = DGData.Columns[i - 1].HeaderText;
        }

        // Storing each row and column value to Excel sheet
        for (int i = 0; i < DGData.Rows.Count - 1; i++)
        {
            for (int j = 0; j < DGData.Columns.Count; j++)
            {
                worksheet.Cells[i + 2, j + 1] = DGData.Rows[i].Cells[j].Value.ToString();
            }
        }

        // Save the application
        string fileName = String.Empty;
        SaveFileDialog saveFileExcel = new SaveFileDialog();

        saveFileExcel.Filter = "Excel files |*.xls|All files (*.*)|*.*";
        saveFileExcel.FilterIndex = 2;
        saveFileExcel.RestoreDirectory = true;

        if (saveFileExcel.ShowDialog() == DialogResult.OK)
        {
            fileName = saveFileExcel.FileName;

            //Fixed-old code: 11 para->add 1:Type.Missing
            workbook.SaveAs(fileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
        }
        else
            return;

        // Exit from the application
        //app.Quit();
    }
    catch (System.Exception ex)
    {

    }
    finally
    {
        app.Quit();
        workbook = null;
        app = null;
    }
}

解决方案

Consider:

System.Threading.Thread.CurrentThread.CurrentCulture = oldCI;

Delete this line or move to under the line that closes the Excel application.

It works for me.
