Extracting excel worksheet into a string in C#

Question

How can i extract excel worksheet into a string using C#? i already have the sheet and can save as txt file but instead of that I want to extract it into a string directly and do some processing.

Answer 1

Something like the following (untested) code should work:

Excel.Application oXL= new Excel.Application();
oXL.Visible = true;
Excel._Workbook oWB = (Excel._Workbook)(oXL.Workbooks.Add( Missing.Value ));
Excel._Worksheet oSheet = (Excel._Worksheet)oWB.ActiveSheet;
string s = (string)oSheet.Cells[1, 1].Value;

Though look at this sample to see how to clean up everything properly etc.
