Examples

The following code example demonstrates how to use the GetFileName, GetExtension, and GetDirectory methods.

StringBuilder sb = new StringBuilder();
String pathstring = Context.Request.FilePath.ToString();
sb.Append("Current file path = " + pathstring + "<br />");
sb.Append("File name = " + VirtualPathUtility.GetFileName(pathstring).ToString() + "<br />");
sb.Append("File extension = " + VirtualPathUtility.GetExtension(pathstring).ToString() + "<br />");
sb.Append("Directory = " + VirtualPathUtility.GetDirectory(pathstring).ToString() + "<br />");
Response.Write(sb.ToString());

Dim sb As New StringBuilder()
Dim pathstring As String = Context.Request.FilePath.ToString()
sb.Append("Current file path = " & pathstring & "<br />")
sb.Append("File name = " & VirtualPathUtility.GetFileName(pathstring).ToString() & "<br />")
sb.Append("File extension = " & VirtualPathUtility.GetExtension(pathstring).ToString() & "<br />")
sb.Append("Directory = " & VirtualPathUtility.GetDirectory(pathstring).ToString() & "<br />")
Response.Write(sb.ToString())

Remarks

If virtualPath is not rooted; that is, it does not equal the root operator (the tilde [~]), does not start with a tilde (~), such as a tilde and a slash mark (~/) or a tilde and a double backslash (~//), or does not start with a slash mark (/), an ArgumentException exception is thrown.

If the virtual path that is passed into the GetDirectory method is "/images/image1.gif", the returned directory is "/images".
