Question

我尝试将WCF服务用于原始邮件。

1）WCF服务代码：

[DataContract]
public class Person
{
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public string FirstName { get; set; }

    [DataMember]
    public string LastName { get; set; }
}

public static List<Person> CreateEmployees()
{
    List<Person> lstPersons = new List<Person>()
    {
        new Person { Id = 1, FirstName = "Andrey", LastName = "Andreyev" },
        new Person { Id = 2, FirstName = "Sergey", LastName = "Sergeyev" }
    };

    return lstPersons;
}

[ServiceContract]
public interface ITestService
{
    [OperationContract(Action = TestService.RequestAction, ReplyAction = TestService.ReplyAction)]
    Message GetPersonById(Message id);
}

public class TestService : ITestService
{
    public const String ReplyAction = "http://localhost:4249/Message_ReplyAction";
    public const String RequestAction = "http://localhost:4249/Message_RequestAction";

    public Message GetPersonById(Message id)
    {
        string firstName = Employees.CreateEmployees().First(e => e.Id == id.GetBody<int>()).FirstName;
        Message response = Message.CreateMessage(id.Version, ReplyAction, firstName);
        return response;
    }
}

2）客户代码：

static void Main(string[] args)
{
    TestServiceClient client = new TestServiceClient();
    String RequestAction = "http://localhost:4249/Message_RequestAction";
    int value = 1;
    Message request = Message.CreateMessage(MessageVersion.Default, RequestAction, value);
    Message reply = client.GetPersonById(request);
    string firstName = reply.GetBody<string>();

    Console.WriteLine(firstName);
    client.Close();
}

当我使用：int value = 1运行客户端时，一切正常。但是，当我使用：int value = 2时，我收到以下错误：

System.Runtime.Serialization.SerializationException未处理消息=＆＃34;第1行位置错误276.期望元素＆＃39;字符串＆＃39;来自命名空间＆＃39; http://schemas.microsoft.com/2003/10/Serialization/＆＃39; ..遇到＆＃39;元素＆＃39;名称＆＃39;故障＆＃39;，命名空间＆＃39; http://www.w3.org/2003/05/soap-envelope＆＃39;。＆＃34; 源=＆＃34; System.Runtime.Serialization＆＃34; 堆栈跟踪：在System.Runtime.Serialization.DataContractSerializer.InternalReadObject（XmlReaderDelegator xmlReader，Boolean verifyObjectName）在System.Runtime.Serialization.XmlObjectSerializer.ReadObjectHandleExceptions（XmlReaderDelegator reader，Boolean verifyObjectName）在System.Runtime.Serialization.XmlObjectSerializer.ReadObject（XmlDictionaryReader reader）在System.ServiceModel.Channels.Message.GetBody [T]（XmlObjectSerializer序列化程序）在System.ServiceModel.Channels.Message.GetBodyT atE：\ Projekti \ WCF \ Parus \ ClientTestService \ ClientTestService \ Program.cs中的ClientTestService.Program.Main（String [] args）：第22行在System.AppDomain._nExecuteAssembly（Assembly assembly，String [] args）在System.AppDomain.ExecuteAssembly（String assemblyFile，Evidence assemblySecurity，String [] args）在Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly（）在System.Threading.ThreadHelper.ThreadStart_Context（对象状态）在System.Threading.ExecutionContext.Run（ExecutionContext executionContext，ContextCallback回调，对象状态）在System.Threading.ThreadHelper.ThreadStart（） InnerException：

在线：

string firstName = reply.GetBody<string>();

服务已启动，我已通过＆＃34;添加服务参考...＆＃34;添加了服务参考。在VS2008中。我使用的是.NET Framework 3.5。

我不确定为什么我会收到此错误。

当我不使用Message类时，一切正常。我的意思是：

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    Person GetPersonById(int id);
}

public class TestService : ITestService
{
    public Person GetPersonById(int id)
    {
        Person person = Employees.CreateEmployees().First(e => e.Id == id);
        return person;
    }
}

2）客户代码：

static void Main(string[] args)
{
    TestServiceClient client = new TestServiceClient();
    int value = 1;
    Person person = client.GetPersonById(value);

    Console.WriteLine(person.FirstName);
    client.Close();
}

如果有人可以提供帮助，我会非常感激。

Answer 1

Message reply = client.GetPersonById(request); 
if(reply.IsFault)
  throw new GoransException(reply.toString());
string firstName = reply.GetBody<string>();
//...

WCF：使用System.ServiceModel.Channels.Message类的问题？
