示例

下面的示例使用了从 MessageDescription 类的 Messages 属性返回的 OperationDescription。 该代码循环访问终结点集合，并输出每个终结点的名称以及终结点中的每个操作的名称。

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);
            Console.WriteLine("\t\tActions:");
            for (k  = 0; k < opDesc.Messages.Count; k++)
            {
                // 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.
                mBodyDesc = methDesc.Body;
                if (mBodyDesc.Parts.Count > 0)
                {
                    for (l = 0; l < methDesc.Body.Parts.Count; l++)
                    {
                        partDesc = methDesc.Body.Parts[l];
                        Console.WriteLine("\t\t\t\t{0}",partDesc.Name);
                    }
                }
            }
        }
    }
}

注解

MessageDescription 包含 Headers 和 Body 属性，可提供对这些消息部分的访问。 Direction 属性可指示此消息是传入消息还是传出消息。 它还提供一个 Action 属性，其中 URI 指示可以指定消息的意图。

构造函数

MessageDescription(String, MessageDirection)

用指定的操作和方向初始化 MessageDescription 类的新实例。

属性

Action	获取或设置标识消息意图的 SOAP 消息的操作参数。
Body	获取 SOAP 消息的正文。
Direction	获取指示消息是传入消息还是传出消息的方向。
HasProtectionLevel	获取一个指示 ProtectionLevel 是否已设置的值。
Headers	获取 SOAP 消息的标头的说明。
MessageType	获取或设置标识消息协定类型的类型。
Properties	获取 SOAP 消息属性的说明。
ProtectionLevel	获取或设置消息所需的安全服务。

方法

Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ShouldSerializeProtectionLevel()	返回一个值，该值指示 ProtectionLevel 属性是否已更改，不再是默认值且应对其进行序列化。
ToString()	返回表示当前对象的字符串。 (继承自 Object)
