WCF的几种寄宿方式

1、 WCF服务的控制台程序寄宿

namespace WcfService_HostConsole
{
    class Program
    {
        static void Main(string[] args)
        {            
            try
            {
                ServiceHost serviceHost = new ServiceHost(typeof(Service1));
                if (serviceHost.State != CommunicationState.Opened)
                {
                    serviceHost.Open();
                }

                Console.WriteLine("WCF 服务正在运行......");
                Console.WriteLine("输入回车键 <ENTER> 退出WCF服务");
                Console.ReadLine();
                serviceHost.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
            }
        }
    }
}

2、WCF服务的Winform程序寄宿

namespace WcfService_HostWinform
{
    public partial class FrmMain : Form
    {
        ServiceHost serviceHost = null;
        BackgroundWorker worker = null;

        public FrmMain()
        {
            InitializeComponent();

            worker = new BackgroundWorker();
            worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);
            worker.DoWork += new DoWorkEventHandler(worker_DoWork);

            if (!worker.IsBusy)
            {
                textBox1.Text = "正在启动......";
                worker.RunWorkerAsync();
            }
        }

        void worker_DoWork(object sender, DoWorkEventArgs e)
        {
            try
            {
                serviceHost = new ServiceHost(typeof(Service1));
                if (serviceHost.State != CommunicationState.Opened)
                {
                    serviceHost.Open();
                }

                e.Result = "正常";
            }
            catch (Exception ex)
            {
                e.Result = ex.Message;
            }
        }

        void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            if (e.Result != null)
            {
                if (e.Result.ToString() == "正常")
                {
                    textBox1.Text = "服务正在进行侦听......";
                }
                else
                {
                    textBox1.Text = string.Format("错误：{0}", e.Result);
                }
            }
        }
    }
}

 

3、 使WCF服务支持GET方式调用

namespace WcfServiceForWinform
{
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        void DoWork();

        [OperationContract]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
        string GetData(int value);
    }
}

namespace WcfServiceForWinform
{
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1 : IService1
    {
        public void DoWork()
        {
        }

        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
    }
}
