窗口应用程序与网站WCF web服务通信

我是新手，在实现与windows应用程序和网站WCF web服务的通信方面遇到问题。它一直显示错误，我已经试过很多次了。希望有人能帮我~~

网站

IApiService.cs

[ServiceContract]
public interface IApiService
{
    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean TestConnection();
    [OperationContract]  
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    Boolean IsPhoneNumberListMatch(int pa, int pb);
    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientPhoneModel> GetAllPhoneNumber(string pa);
    [OperationContract]
    [WebInvoke(Method = "POST",
          BodyStyle = WebMessageBodyStyle.Wrapped,
          ResponseFormat = WebMessageFormat.Json)]
    List<ClientRegistrationModel> GetAllNewRegistration(string pa);
}

web.config

<system.serviceModel>
    <behaviors>
        <endpointBehaviors>
        <behavior name="EndBehavior">
            <webHttp />
        </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
        <behavior name="ServiceBehavior">

        </behavior>
    </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="ServiceBehavior" name="ApiService">
            <endpoint address="basic" binding="webHttpBinding" contract="IApiService" behaviorConfiguration="EndBehavior"/>
        </service>
        <service behaviorConfiguration="ServiceBehavior" name="WebService">
            <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="EndBehavior"/>
        </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
</system.serviceModel>

窗口应用程序

添加localhost:551/ApiService.svc作为服务参考

索引.cs

try {
    Localhost.ApiServiceClient client = new Localhost.ApiServiceClient();
    client.TestConnection();
}
catch(Exception ex) {
    Log.Exception(ex);
}

应用程序配置

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
                <behavior name="ServiceBehavior">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
        </serviceBehaviors>
        <endpointBehaviors>
            <behavior name="EndBehavior">
                <webHttp/>
            </behavior>
        </endpointBehaviors>
    </behaviors>
    <client>
        <endpoint address="http://localhost:5151/ApiService.svc" behaviorConfiguration="EndBehavior" binding="webHttpBinding" contract="Localhost.IApiService" name="ApiServiceClient" />
    </client>
</system.serviceModel>

我能得到的最新错误是

Message : 
    Operation 'IsPhoneNumberListMatch' of contract 'IApiService' specifies multiple request body parameters to be serialized without any wrapper elements. At most one body parameter can be serialized without wrapper elements. Either remove the extra body parameters or set the BodyStyle property on the WebGetAttribute/WebInvokeAttribute to Wrapped.
