public:
 property System::String ^ Authority { System::String ^ get(); };
public string Authority { get; }
member this.Authority : string
Public ReadOnly Property Authority As String

Property Value

A String containing the authority component of the URI represented by this instance.

Exceptions

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

Examples

The following example writes the host name (www.contoso.com) and port number (8080) of the server to the console.

Uri^ baseUri = gcnew Uri( "http://www.contoso.com:8080/" );
Uri^ myUri = gcnew Uri( baseUri,"shownew.htm?date=today" );
Console::WriteLine( myUri->Authority );
Uri baseUri = new Uri("http://www.contoso.com:8080/");
Uri myUri = new Uri(baseUri,"shownew.htm?date=today");

Console.WriteLine(myUri.Authority);
  
Dim baseUri As New Uri("http://www.contoso.com:8080/")
Dim myUri As New Uri(baseUri,"shownew.htm?date=today")
       
Console.WriteLine(myUri.Authority)

Remarks

The Authority property is typically a server DNS host name or IP address. This property might include the service port number if it differs from the default port for the URI. If the Authority component contains reserved characters, these are escaped in the string value returned by this property.
