在C＃中将DataGridView数据导出到Excel文件

Question

I need to export data from DataGridView (in my WinForms application) to excel file. I googled some tutorials on the subject, but I'm having hard time getting any of the available solutions to work.

I started with this tutorial . But when I try to export datagridview to excel file i get Unhandled COMException in:

 Microsoft.Office.Interop.Excel.ApplicationClass ExcelApp = new 
 Microsoft.Office.Interop.Excel.ApplicationClass();

I've also tried this tutorial , but with the same result.

Another of the articles I've found and read was this one . Couldn't get code to work, probably because I can't find Microsoft Excel 12.0 object library in the COM tab of Add Reference dialog.

I'm using Visual Studio 2010 Ultimate.

Answer 1

If those libraries are not installed, you can download them from Microsoft:

For Specific office versions, see here:

Office 2003 Update: Redistributable Primary Interop Assemblies

2007 Microsoft Office System Update: Redistributable Primary Interop Assemblies

Microsoft Office 2010: Primary Interop Assemblies Redistributable

Once you install the correct one, you should be able to find the library in the 'Add reference' section of the tutorials

Answer 2

One day I did what you need but I got it in VB.Net

So you just need to create a Class Library project and in that class use my method so you can reference it through C#.

Take a look at this link (translate it to English): http://foro.elhacker.net/net/aporte_exportar_datagridview_a_excel_pdf_y_html-t299075.0.html

and also you can download my example from here and re-use my method: http://dl.dropbox.com/u/15208254/stackoverflow/ExportarData.rar

您可以使用Excel Package Plus并导出数据，而无需excel或任何其他外部依赖
