Uri.IsDefaultPort Property

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

Uri.cs

Gets a value that indicates whether the port value of the URI is the default for this scheme.

public:
 property bool IsDefaultPort { bool get(); };

public bool IsDefaultPort { get; }

member this.IsDefaultPort : bool

Public ReadOnly Property IsDefaultPort As Boolean

Property Value

Boolean

true if the value in the Port property is the default port for this scheme; otherwise, false.

Exceptions

InvalidOperationException

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

Examples

The following example creates a Uri instance and checks whether it uses the default port.

// 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
