Syntax
Remarks
The System.Web.VirtualPathUtility class provides utility methods for common operations involving virtual paths. For ASP.NET server controls and server code, virtual paths using the Web application root operator, the tilde (~), commonly are used instead of relative and absolute paths. For more information, see ASP.NET Web Site Paths.
Use the System.Web.VirtualPathUtility class when you need to convert application-relative paths to absolute virtual paths, as might be the case in developing a custom Web service handler.
An absolute virtual path starts with the literal slash mark (/). A relative virtual path is relative to the application root directory, if it is just a tilde (~) or starts with the tilde and a double backslash (~\\) or the tilde and a slash mark (~/). Making a virtual path relative makes the path independent of the application.
The virtual directory for the application can be obtained from the HttpRuntime.AppDomainAppVirtualPath and HttpRequest.ApplicationPath properties.
The System.Web.VirtualPathUtility class is not intended for security or canonicalization purposes. For more information about Web application security, see Overview of Web Application Security Threats. For generic URL processing functionality, see Uri.
