• WCF 小实例


    服务端:

    namespace WcfServiceFist
    {
        [ServiceContract]
        public interface IServiceFirst
        {
            [OperationContract]
            double GetSum(int x, double y);

            [OperationContract]
            int GetX();
        }

        [DataContract]
        public class CompositeType
        {
            [DataMember]
            public int X { get; set; }
            [DataMember]
            public double Y { get; set; }

            public double Sum()
            {
                return X + Y;
            }
        }
    }

    namespace WcfServiceFist
    {
        public class ServiceFirst : IServiceFirst
        {
            CompositeType Com = new CompositeType();

            public double GetSum(int x, double y)
            {
                Com.X = x;
                Com.Y = y;
                return Com.Sum();
            }
            public int GetX()
            {
                return Com.X;
            }
        }
    }
    创建一个宿主程序,比如winform

    创建一个Config

    <configuration>
      <system.serviceModel>
        <services>
          <service name="WcfServiceFist.ServiceFirst" behaviorConfiguration="WcfServiceFist.ServiceFirstBehavior">
            <host>
              <baseAddresses>
                <!--添加服务调用地址-->
                <add baseAddress="http://192.168.0.10:8200/">
              </baseAddresses>
            </host>


            <!-- Service Endpoints -->
            <endpoint address="" binding="wsHttpBinding" contract="WcfServiceFist.IServiceFirst">
              <!--
                  部署时,应删除或替换下列标识元素,以反映
                 用来运行所部署服务的标识。删除之后,WCF 将
                  自动推断相应标识。
              -->
              <identity>
                <dns value="192.168.0.10"/>
              </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
          </service>
        </services>
        <behaviors>
          <serviceBehaviors>
            <behavior name="WcfServiceFist.ServiceFirstBehavior">
              <!-- 为避免泄漏元数据信息,请在部署前将以下值设置为 false 并删除上面的元数据终结点 -->
              <serviceMetadata httpGetEnabled="true"/>
              <!-- 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 includeExceptionDetailInFaults="true"/>
            </behavior>
          </serviceBehaviors>
        </behaviors>
      </system.serviceModel>

    </configuration>

    配置文件:

    <service name="WcfServiceFist.ServiceFirst" behaviorConfiguration="WcfServiceFist.ServiceFirstBehavior">

    <endpoint address="" binding="wsHttpBinding" contract="WcfServiceFist.IServiceFirst">

    <behavior name="WcfServiceFist.ServiceFirstBehavior">

    在宿主程序中添加打开服务与关闭服务的功能

    private ServiceHost _ServiceHost = new ServiceHost(typeof(WcfServiceFist.ServiceFirst));
            private void btnOpen_Click(object sender, RoutedEventArgs e)
            {
                if (_ServiceHost.State != CommunicationState.Opened)
                {
                    try
                    {
                        _ServiceHost.Open();
                        MessageBox.Show("打开成功");
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }
            }

            private void btnClose_Click(object sender, RoutedEventArgs e)
            {
                if (_ServiceHost.State != CommunicationState.Closed)
                {
                    try
                    {
                        _ServiceHost.Close();
                        MessageBox.Show("关闭成功");
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }
                }
            }

    打开服务之后,创建一个客户端,把

    http://192.168.0.10:8200/作为服务引用的地址(服务端得开启并打开),添加服务引用。

    这样之后就跟webservice使用方法一致了

    private void button1_Click(object sender, EventArgs e)
            {
                ServiceFirstClient sfc = new ServiceFirstClient();
                MessageBox.Show(sfc.GetSum(10, 10.9).ToString()); //结果20.9
                MessageBox.Show(sfc.GetX().ToString()); //结果10
            }
