wcf简单问题请教

Question

我新建了wcf服务。申明两个接口，都实现了。
http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/
http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/MessageHello/为什么在另外项目添加服务引用的时候，只能找到Service1，而找不到MessageHello服务的配置文件
          <baseAddresses>
            <add baseAddress = "http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/" />
          </baseAddresses>          <baseAddresses>
            <add baseAddress = "http://localhost:8731/Design_Time_Addresses/WcfServiceLibrary1/MessageHello/" />
          </baseAddresses>
都加上了。在IE中直接输入地址，Service1可以访问，MessageHello报400错

Answer 1

检查MessageHello的代码...有异常，先做好单元测试...

Answer 2

我贴出来
IMessagingHello.cs
    [ServiceContract]
    interface IMessagingHello
    {
        [OperationContract]
        CustomMessage Hello(HelloGreetingMessage msg);
    }MessageHello.cs
    public class MessageHello:IMessagingHello
    {
        public CustomMessage Hello(HelloGreetingMessage msg) 
        {
            Console.WriteLine("Caller sent: " + msg.Greeting);
            CustomMessage customMessage = new CustomMessage();
            customMessage.Response = "Service Received: " + msg.Greeting;
            customMessage.ExtraValues = string.Format("Served by object {0}. ", this.GetHashCode().ToString());
            Console.WriteLine("Returned response message.");
            return customMessage;
        }
    }    [MessageContract]
    public class CustomMessage
    {
        private string localResponse = string.Empty;
        private string extra = string.Empty;
        [MessageBodyMember(Name = "abb",
            Namespace = "http://www.xxx.com")]
        public string Response
        {
            get { return localResponse; }
            set { localResponse = value; }
        }        [MessageBodyMember(Name = "cccc",
            Namespace = "http://www.xxx.com")]
        public string ExtraValues
        {
            get { return extra; }
            set { extra = value; }
        }
    }    [MessageContract]
    public class HelloGreetingMessage
    {
        private string localGreeting;
        [MessageBodyMember(Name = "ddddd",
            Namespace = "http://www.xxx.com")]
        public string Greeting 
        {
            get { return localGreeting; }
            set { localGreeting = value; }
        }
    }

Answer 3

我在服务主机上MessageHello状态是错误的，错误信息是：
在服务“MessageHello”实现的协定列表中找不到协定名称“WcfServiceLibrary1.IMessageHello”楼上的哥们帮忙再看看

Answer 4

配置文件不对，要把你的WcfServiceLibrary1.IMessageHello加入到ServiceMetadataBehavior配置...你参考Service1的配置修改一下...

<behavior name="WcfSample.MessageHelloBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="True" />
        </behavior>includeExceptionDetailInFaults="True"这个改为true看看报什么错误

Answer 7

你这配置文件太乱了啊...bindings配置节呢？重建配置文件吧...
