C# 创建一个WCF服务

做代码统计，方便以后使用：

app.config配置文件设置：

<configuration>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webBinding" maxBufferPoolSize="" maxBufferSize="" maxReceivedMessageSize="">
          <readerQuotas maxDepth="" maxStringContentLength="" maxArrayLength="" maxBytesPerRead="" maxNameTableCharCount=""/>
        </binding>
      </webHttpBinding>
    </bindings>

    <behaviors>
      <serviceBehaviors>
        <behavior name="mySerBeh">
          <serviceMetadata httpGetEnabled="true"/>
          <!--httpGetUrl="mex"-->
          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息-->
          <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="webHttpendBehavior">
          <webHttp></webHttp>
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <!-- 看到services节，就表明这是在定义服务相关的内容 -->
    <services>
      <!-- 定义一个服务，name是契约实现类的全名 -->
      <service behaviorConfiguration="mySerBeh" name="WCFExample.WCF.UserService">
        <host>
          <baseAddresses>
            <add baseAddress="http://127.0.0.1:21467/"/>
          </baseAddresses>
        </host>
        <!-- 定义一下终节点，address一般为空，如果不为空，最终服务地址就是在baseAddress的基础上加上这个address，binding指定为basicHttpBinding，
        这是最基础的基于http的绑定方式，contract标明这是为哪个契约服务 -->
        <endpoint address="wcfs" behaviorConfiguration="webHttpendBehavior"
          binding="webHttpBinding" bindingConfiguration="webBinding" contract="WCFExample.WCF.IService"></endpoint>
      </service>
    </services>
  </system.serviceModel>
</configuration>

基本内容可以直接创建一个wpf服务会生成基本内容，服务分成两个，一个去做接口，一个去实现接口：

接口类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Web;

namespace WCFExample.WCF
{

    //需要引用类库 System.ServiceModel 和 System.ServiceModel.Web
    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        [WebInvoke(Method = "GET", UriTemplate = "GetCon?op={name}", ResponseFormat = WebMessageFormat.Json)]
        string GetCon(string name);
    }
}

实现方法类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WCFExample.WCF
{
    /// <summary>
    /// 用ServiceBehavior为契约实现类标定行为属性，此处指定并发模型为ConcurrencyMode.Multiple，即并发访问
    /// </summary>
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
    public class UserService : IService
    {
        public string GetCon(string name)
        {
           return name;
        }
    }
}

启动WCF类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Threading;

namespace WCFExample.WCF
{
    public class WCFService
    {

      public  static void Begion()
        {
            //无配置文件App.config的情况下手动绑定
            //Uri HttpUri = new Uri("Http://localhost:21467/wcf");
            //Type Servicetype = typeof(WCFExample.WCF.UserService);
            //using (ServiceHost Chost=new ServiceHost (Servicetype,new Uri[]{HttpUri}))
            //{
            //    Binding basicHttpBinding = new BasicHttpBinding();
            //    string address = "";
            //Chost.AddServiceEndpoint(typeof(WCFExample.WCF.UserService), basicHttpBinding, address);

            //    Chost.Open();
            //    Console.WriteLine("Service Running...");
            //    Console.ReadKey(true);
            //    Chost.Close();
            //}

            //定义一个ServiceHost，注意参数中要使用契约实现类而不是接口
            ServiceHost host = new ServiceHost(typeof(WCFExample.WCF.UserService));
            host.Open();
            while (true)
                Thread.Sleep();
        }
    }
}

服务启动后，即可正常使用WCF服务
