WCF服务

1.创建一个接口，并给予ServiceContract协议

[SerciveContract]
public interface IWCFService
{
	[OperationContract]
	bool DoLogin(string username, string psswd);
}

2.创建一个继承IWCFService的类WCFService

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single)]
public class WCFService :IWCFService
{

	public bool Dologin(string username, string psswd)
	{
		//实现登录逻辑
	}
}

3.定义宿主寄宿WCF服务

寄宿方式分为4类：
1.”Self-Hosting” in a Managed Application（自托管宿主）
2.Managed Windows Services（Windows Services宿主）
3.Internet Information Services（IIS宿主）
4.Windows Process Activation Service（WAS宿主）

此例以第一种介绍：

string uri = "http://localhost:39005/WCFService";
\\定义ServiceHost
ServiceHost host = new ServiceHost(typeof(WCFService),new Uri(uri))；

\\绑定参数
BasicHttpBinding _basic = new BasicHttpBinding();
_basic.MaxBufferPoolSize = int.MaxValue;
_basic.MaxBufferSize = int.MaxValue;
_basic.MaxReceivedMessageSize = int.MaxValue;

\\行为参数
System.Xml.XmlDictionaryReaderQuotas _readerQuotas = new XmlDictionaryReaderQuotas();
_readerQuotas.MaxArrayLength = int.MaxValue;
_readerQuotas.MaxBytesPerRead = int.MaxValue;
_readerQuotas.MaxDepth = int.MaxValue;
_readerQuotas.MaxNameTableCharCount = int.MaxValue;
_readerQuotas.MaxStringContentLength = int.MaxValue;
_basic.ReaderQuotas = _readerQuotas;

\\开启服务
host.AddServiceEndpoint(typeof(WCFService), _basic, uri);

通常的Windows App都是采用第二种寄主方式，可以随时开启和停止WCF服务
