WCF中，通过C#代码或App.config配置文件创建ServiceHost类

C#

static void Main(string[] args)
{
    //创建宿主的基地址
    Uri baseAddress = new Uri("http://localhost:8080/User");

    //创建宿主
    using (ServiceHost host = new ServiceHost(typeof(User), baseAddress))
    {
        host.AddServiceEndpoint(typeof(IUser), new WSHttpBinding(), "");

        //将HttpGetEnabled属性设置为true
        ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
        smb.HttpGetEnabled = true;

        //将行为添加到Behaviors中
        host.Description.Behaviors.Add(smb);

        //打开宿主
        host.Open();
        Console.WriteLine("WCF中的HTTP监听已启动....");
        Console.ReadLine();
        host.Close();
    }
}

 

App.config
