WCF客户端不接受服务的响应。由于EndpointDispatcher的AddressFilter不匹配，无法在接收方进行处理。

Question

我是第一次写与wcf相关的东西，我按照文档等做了一切，但我不明白为什么我的客户端不想从服务中接收数据。而且，它只接受数据，从服务本身我不调用客户端中的方法，是不是意味着我有单向的wsHttpBinding？

任务如下：服务从客户端接收矩阵大小(5x5)和enum标识符，用于确定如何自己生成矩阵，在服务器上生成一个指定维度的随机矩阵，并返回 Matrix <double> 问题是，当矩阵返回给客户端时，我得到了以下消息，错误在调用GetMatrix方法的那一行。

当接收到HTTP响应到 http:/localhost:8080WCF_TRSPOService1。. 这可能是由于服务端点绑定不使用HTTP协议。

ServiceTrace说我，错误:

该消息与To 'http:/localhost:8080WCF_TRSPOService1mexmex。'不能在接收方处理，因为EndpointDispatcher的AddressFilter不匹配。检查发送方和接收方的EndpointAddresses是否一致。

看，如果我传递给客户端的不是矩阵，而是null，那么客户端就会接受。5x5矩阵则拒绝。同理。Vector <double>.我不明白是什么问题，谷歌搜索没有返回结果。给虽然指示在哪里看或我错在哪里？)

Answer 1

MathNet.Numerics.LinearAlgebra.Double.DenseMatrix'的数据合约名为'DenseMatrix:schemas.datacontract.org200407...'是不希望的。如果使用DataContractSerializer，请考虑使用DataContractResolver，或者将任何静态不已知的类型添加到已知类型列表中--例如，通过使用KnownTypeAttribute属性或将它们添加到传递给序列化器的已知类型列表中。

该错误通常表明服务器端和客户端不知道如何序列化和反序列化复杂的数据类型。由于 Maxtrix<double>, Vector<double> 请考虑用DataContract属性来装饰复杂类型，并使用Known type来预先指定在序列化过程中应考虑的类型。

[DataContract]
[KnownType(typeof(CircleType))]
[KnownType(typeof(TriangleType))]
public class CompanyLogo2
{
    [DataMember]
    private Shape ShapeOfLogo;
    [DataMember]
    private int ColorOfLogo;
}
[DataContract]
public class Shape { }

[DataContract(Name = "Circle")]
public class CircleType : Shape { }

[DataContract(Name = "Triangle")]
public class TriangleType : Shape { }
