What does Request.MapPath() do and how does it work?

I want to access a file that's in a folder for the default Physical Path. So the following code works:

String outPutPath = Path.GetDirectoryName(Request.PhysicalPath) + "\\output";
StreamWriter w = File.AppendText(outPutPath + "\\xmleventsincall.txt");

Is there a nicer way of doing this using MapPath()?

Thanks,

above not worked?

Yes, but what is keeping track of the location of "Hello.aspx"? And what if there are two copies of that file in different directories?

so does that mean IIS does not allow you to have the same file in two subfolders?

ASKER

In your example, Hello.aspx is located in three folders. I don't see how it can tell you the path in that case.
