The GetLeftPart method returns a string containing the leftmost portion of the URI string, ending with the portion specified by part.
GetLeftPart includes delimiters in the following cases:
Scheme includes the scheme delimiter.
Authority does not include the path delimiter.

The following example creates a Uri instance and writes the path to the console.
// Create Uri Uri uriAddress = new Uri("http://www.contoso.com/index.htm#search"); Console.WriteLine(uriAddress.Fragment); Console.WriteLine("Uri {0} the default port ", uriAddress.IsDefaultPort ? "uses" : "does not use"); Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path)); Console.WriteLine("Hash code {0}", uriAddress.GetHashCode());
