WCF 创建步骤

app server

1. 建立宿主项目，添加一个svc文件

这个svc文件的内容为：

<%@ ServiceHost Language="C#" Debug="true" Service="bc.WorkBc"%>

bc.workBc 中的bc表示项目名称，workBc表示类名，如下图：

2.配置wcf，最简单的模式

<system.serviceModel>
    <services>
        <service name="contract.IWork">
            <endpoint address="http://localhost:9789/TestService.svc" binding="basicHttpBinding"
                bindingConfiguration="" contract="contract.IWork" />
        </service>
    </services>
</system.serviceModel>

3.实现bc中workBc类的方法

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)]
class WorkBc : IWork
{
    public Student GetName()
    {
        return new Student { Name = "qqq" };
    }
}

接口类：

[ServiceContract]
public interface IWork
{
    [OperationContract]
    Student GetName();
}

实体类：

public class Student
{
    public string Name { get; set; }
}

web server

方法1 手动生成

1.配置文件

<system.serviceModel>
       <client>
           <endpoint address="http://localhost:9789/TestService.svc" binding="basicHttpBinding"
               bindingConfiguration="" contract="contract.IWork" name="contract.IWork"
               kind="" endpointConfiguration="" />
       </client>
   </system.serviceModel>

2.调用app server中定义好的方法

protected void Page_Load(object sender, EventArgs e)
{
    string endpointName = "contract.IWork";
    IWork proxy = GetService<IWork>(endpointName);
    Student stu=proxy.GetName();
    ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "showName", "alert('" + stu.Name + "')", true);
}

private T GetService<T>(string endpointName)
{
    ChannelFactory<T> channel = new ChannelFactory<T>(endpointName);
    return channel.CreateChannel();
}

2.通过添加服务引用来自动生成
