VirtualPathUtility.GetDirectory Method

Note: This method is new in the .NET Framework version 2.0.

Returns the directory portion of a virtual path.

Namespace: System.Web
Assembly: System.Web (in system.web.dll)

public static string GetDirectory (
	string virtualPath
)
public static String GetDirectory (
	String virtualPath
)
public static function GetDirectory (
	virtualPath : String
) : String

Parameters

virtualPath

The virtual path.

Return Value

The directory referenced in the virtual path.

Exception typeCondition

ArgumentException

virtualPath is not rooted.

- or -

virtualPath is a null reference (Nothing in Visual Basic) or an empty string.

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".

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());
