WCF服务如何从方法返回多个响应 [英] How WCF Service returns multiple response from Method

问题描述

大家好，
我有一个WCF服务和一个在服务中名为public GetDataUsingMethodList()的单一方法.当它返回单一响应时，它可以正常工作.
但是我想返回多个响应，即List和String都来自方法GetDataUsingMethodList().

请帮助我.

Hi guys,
Hi I have one WCF service and one single method named public GetDataUsingMethodList() in the service.It''s working fine when it''s return single response.
But i want to return multiple response i.e. List and String both from Method GetDataUsingMethodList().

Please help me on this.

推荐答案

使用DataContract.
例如:

Use DataContract.
For Example:

[DataContract]
public class Result 
{
    [DataMember]
    public List<int> ListOutPut { get;set;}

    [DataMember]
    public String StringOutPut { get;set;}
}

现在，将其用作合同中的返回类型，即在服务类及其接口中.
例如:

Now, use this as the return type in your contract, i.e. both in service class and its interface.
For example:

public interface IService
{
    Result GetDataUsingMethodList();
}

public class Service : IService
{
    public Result GetDataUsingMethodList()
    {
        // create the result and return it.
    }
}

这样，您可以在输出中实现多种类型.

This way, you can achieve multiple types within the output.
