Hi,
This line doesn't look right:
string excelPath = Server.MapPath("http://brainlines.in/starsforum.org/Forum/Excel Sheets_Individuals/") + Path.GetFileName(FileUpload1.PostedFile.FileName);
If you have a look at the documentation for the
Server.MapPath Method[
^], you will see examples of it's correct usage.
I would expect the following to be closer to what you want:
string excelPath = Server.MapPath(string.Concat("/Forum/Excel Sheets_Individuals/",FileUpload1.PostedFile.FileName));
... hope it helps.
