我如何调用WCF服务 [英] How can i call a WCF Service

问题描述

每一个

i有一个wcf服务（Chat_Server）

我用命令做了一个web.config和callback类：

Hi every one
i have a wcf service (Chat_Server)
and i made a web.config and callback class with command :

svcutil.exe http://localhost:1462/Service_Chat.svc?wsdl

这是我的配置：

this is my config :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <bindings>
      <wsDualHttpBinding>
        <binding name="WSDualHttpBinding_IService_Chat">
          <reliableSession inactivityTimeout="00:01:00" />
          <security mode="None" />
        </binding>
      </wsDualHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:1462/Service_Chat.svc" binding="wsDualHttpBinding"

          bindingConfiguration="WSDualHttpBinding_IService_Chat" contract="IService_Chat"

          name="WSDualHttpBinding_IService_Chat" />
    </client>
  </system.serviceModel>
</configuration>

这是我的班级（Service_ChatClient）名称：

and this is my class with (Service_ChatClient) name :

    End Sub

    Public Sub Disconnect(ByVal Username As String) Implements IService_Chat.Disconnect
        MyBase.Channel.Disconnect(Username)
    End Sub
End Class

现在我不知道如何创建我的新类（Service_ChatClient）并将其称为方法？

谢谢。

Now i don't know how can i make a new class of my ( Service_ChatClient ) and call it methods?
thank you.

推荐答案

你可以创建你生成的对象代理类并调用你想要使用的方法。

You Can just create object proxy class you have generated and call the methods you want to use.

你好，新浪，



首先你必须创建如下的客户对象 -

Hi Sina,

First you have to create client object like below-

Dim cnt As New ServiceReference1.Service1Client

然后使用下面的客户端对象消耗服务方法 -

and then consume service method by using client object like below-

cnt.YourServiceMethod(param1,param2)

就像普通的本地方法一样。

just as normal local method.
