MessageDescription

Esempio

Nell'esempio seguente viene utilizzata la classe MessageDescription restituita dalla proprietà Messages della classe OperationDescription. Il codice scorre la raccolta di endpoint e stampa ogni nome di endpoint nonché il nome di ogni operazione nell'endpoint.

private void PrintDescription(ServiceHost sh)
{
    // Declare variables.
    int i, j, k, l, c;
    ServiceDescription servDesc = sh.Description;
    OperationDescription opDesc;
    ContractDescription contractDesc;
    MessageDescription methDesc;
    MessageBodyDescription mBodyDesc;
    MessagePartDescription partDesc;
    IServiceBehavior servBeh;
    ServiceEndpoint servEP;

    // Print the behaviors of the service.
    Console.WriteLine("Behaviors:");
    for (c = 0; c < servDesc.Behaviors.Count; c++)
    {
        servBeh = servDesc.Behaviors[c];
        Console.WriteLine("\t{0}", servBeh.ToString());
    }

    // Print the endpoint descriptions of the service.
    Console.WriteLine("Endpoints");
    for (i = 0; i < servDesc.Endpoints.Count; i++)
    {
        // Print the endpoint names.
        servEP = servDesc.Endpoints[i];
        Console.WriteLine("\tName: {0}", servEP.Name);
        contractDesc = servEP.Contract;

        Console.WriteLine("\tOperations:");
        for (j = 0; j < contractDesc.Operations.Count; j++)
        {
            // Print the operation names.
            opDesc = servEP.Contract.Operations[j];
            Console.WriteLine("\t\t{0}", opDesc.Name);

            {
                // Print the message action.
                methDesc = opDesc.Messages[k];
                Console.WriteLine("\t\t\tAction:{0}", methDesc.Action);

                // Check for the existence of a body, then the body description.
