KB101679

This code shows how to ask the webserver where the site's root directory is, and how to convert a relative path (like /Uploads) to the full filesystem path.  This will work across environments (i.e. Development/QA/Production).

Syntax Example:
string ServerPath2 = Server.MapPath(@"~/");

This gives the full path to the webserver's root directory. 

Example:

"C:\\Documents and Settings\\All Users\\Documents\\Visual Studio 2008\\WebSites\\MySite\\"

string ServerPath2 = Server.MapPath(@"~/Uploads");

This gives the full path to the Uploads subdirectory - even if it is a virtual directory in another location! 

...even if it is not a browsable web directory (such as APP_CODE or APP_DATA).

This is quite useful when creating logs or reading config files; but my number one use is when using FileUpload objects on a web page.  Look how easy it is to store an uploaded file in the /uploads subdirectory!

string ServerPath = Server.MapPath(@"~/Uploads");
if (FileUpload1.HasFile)
{
String ThisFile = string.Format(@"{0}\{1}", ServerPath, FileUpload1.FileName);
FileUpload1.SaveAs(ThisFile);
}

Piece of cake, right?
