Namespace:  System
Assembly:  System (in System.dll)

public string Authority { get; }

Property Value

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

ExceptionCondition
InvalidOperationException

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

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.

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

Uri baseUri = new Uri("http://www.contoso.com:8080/");
Uri myUri = new Uri(baseUri,"shownew.htm?date=today");

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

	Console::WriteLine(myUri->Authority);
