public bool IsFile { get; }

A Boolean value that is true if the Uri is a file URI; otherwise, false.

This instance represents a relative URI, and this property is valid only for absolute URIs.

The IsFile property is true when the Scheme property equals UriSchemeFile.

The following example creates a Uri instance and determines whether it is a file URI.


Uri uriAddress2 =  new Uri("file://server/filename.ext");
Console.WriteLine(uriAddress2.LocalPath);
Console.WriteLine("Uri {0} a UNC path", uriAddress2.IsUnc ? "is" : "is not");
Console.WriteLine("Uri {0} a local host", uriAddress2.IsLoopback ? "is" : "is not");
Console.WriteLine("Uri {0} a file", uriAddress2.IsFile ? "is" : "is not");
