Datasource or Linq Result to excel with VB.Net

i have found alot of sh*** right now. But not the things that im looking for.

I need to export a LINQ query (or the Datasource of my DataGridview) to an existing Excel Spreadsheet. Le开发者_JAVA技巧ts Say after Cell A25

I have a Windows Form application using LINQ for the Databindings.

Any Suggestions or good Examples?

Thanks in Advance

I would recommend to use EPPlus because it's simple, powerful and works without having office/excel being installed with Excel 2007 spreadsheets(xlsx-files). It's license model is GPL.

Dim excel As New ExcelPackage
excel.File = New IO.FileInfo("C:\Temp\AnExcelFile.xlsx")
If excel.File.Exists Then excel.Load(excel.File.Open(FileMode.Open))
Dim ws As ExcelWorksheet = excel.Workbook.Worksheets.Add("Worksheet-Name")'must be unique and less than 31 characters long'
ws.Cells(26, 1).LoadFromDataTable(dt, True) 'loading from DataTable, the 2.Parameter is PrintHeaders'
ws.Cells(26, 1).LoadFromCollection(query, True)'loading by LINQ-Query'
excel.Save()

I don't think that you can use it for xls-files without problems. Have a look what Jan said: http://epplus.codeplex.com/discussions/253371

No, only XLSX, but you can open it in Excel 2003 if you have the compatibility pack installed. If you need XLS, have a look at the NPOI project here on Codeplex.
