 System::String ^ GetLeftPart(UriPartial part);
public string GetLeftPart (UriPartial part);
member this.GetLeftPart : UriPartial -> string
Public Function GetLeftPart (part As UriPartial) As String

Parameters

The following example creates a Uri instance and writes the path to the console.

// Create Uri Uri^ uriAddress = gcnew Uri( "http://www.contoso.com/index.htm#search" ); Console::WriteLine( uriAddress->Fragment ); Console::WriteLine( "Uri {0} the default port ", uriAddress->IsDefaultPort ? (String^)"uses" : "does not use" ); Console::WriteLine( "The path of this Uri is {0}", uriAddress->GetLeftPart( UriPartial::Path ) ); Console::WriteLine( "Hash code {0}", uriAddress->GetHashCode() ); // The example displays output similar to the following: // #search // Uri uses the default port // The path of this Uri is http://www.contoso.com/index.htm // Hash code -988419291 // 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()); // The example displays output similar to the following: // #search // Uri uses the default port // The path of this Uri is http://www.contoso.com/index.htm // Hash code -988419291 // Create Uri let uriAddress = Uri "http://www.contoso.com/index.htm#search" printfn $"{uriAddress.Fragment}" printfn $"""Uri {if uriAddress.IsDefaultPort then "uses" else "does not use"} the default port """ printfn $"The path of this Uri is {uriAddress.GetLeftPart UriPartial.Path}" printfn $"Hash code {uriAddress.GetHashCode()}" // The example displays output similar to the following: // #search // Uri uses the default port // The path of this Uri is http://www.contoso.com/index.htm // Hash code -988419291 ' Create Uri Dim uriAddress As New Uri("http://www.contoso.com/index.htm#search") Console.WriteLine(uriAddress.Fragment) Console.WriteLine("Uri {0} the default port ", If(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()) ' The example displays output similar to the following: ' #search ' Uri uses the default port ' The path of this Uri is http://www.contoso.com/index.htm ' Hash code -988419291

Remarks

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.

  • Path includes any delimiters in the original URI up to the query or fragment delimiter.

  • Query includes the Path , plus the query and its delimiter.

    The following examples show a URI and the results of calling GetLeftPart with Scheme , Authority , Path , or Query .

    Scheme Authority Query http://www.contoso.com http://www.contoso.com/index.htm http://www.contoso.com/index.htm?date=today http://www.contoso.com/index.htm#main http:// http://www.contoso.com http://www.contoso.com/index.htm http://www.contoso.com/index.htm mailto:user@contoso.com?subject=uri mailto: mailto:user@contoso.com mailto:user@contoso.com?subject=uri nntp://news.contoso.com/123456@contoso.com nntp:// nntp://news.contoso.com nntp://news.contoso.com/123456@contoso.com nntp://news.contoso.com/123456@contoso.com news:123456@contoso.com news: news:123456@contoso.com news:123456@contoso.com file://server/filename.ext file:// file://server file://server/filename.ext file://server/filename.ext
