Definizione

Spazio dei nomi:

System

Assembly:

System.Runtime.dll

Assembly:

System.dll

Assembly:

netstandard.dll

Ottiene un valore che indica se il valore della porta dell'URI è il valore predefinito per questo schema.

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

public bool IsDefaultPort { get; }

member this.IsDefaultPort : bool

Public ReadOnly Property IsDefaultPort As Boolean

Valore della proprietà

Boolean

true se il valore nella Port proprietà è la porta predefinita per questo schema; in caso contrario, false.

Eccezioni

InvalidOperationException

Questa istanza rappresenta un URI relativo e questa proprietà è valida solo per URI assoluti.

Esempio

L'esempio seguente crea un'istanza Uri e verifica se usa la porta predefinita.

// 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
