Hi, i have a fileupload control from which i need the path of a text file. After selecting the file,i need to open the file for reading the data from the text file.For this, i used the following code to open the text file.

fp=File.OpenText(FileUpload2.PostedFile.FileName)

This is working fine in my system.The FileUpload2.PostedFile.FileName statement gives the path of the file.The File.OpenText method opens the selected file.But when i run my project in IIS,it gives the following error:

"File.OpenText is not declared."

The FileUpload2.PostedFile.FileName statement is not retrieving the path, it retrieves only only the filename.what could be the reason?
