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

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();
}
}
