ExceptionCondition
InvalidOperationException

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