???? 現網上關于WCF所謂是很多,但好書很少.Programming WCF Services 應該算是一本非常好的書。結合書和代碼總結一下.

一.服務器端操作重載

1.接口本身支持重載

interface ICalculator{int Add(int arg1, int arg2);double Add(double arg1, double arg2);}

2.若將此接口作為服務契約,WSDL規定方法不可重載

以下定義是錯誤的

//Invalid contract definition:[ServiceContract]interface ICalculator{[OperationContract]int Add(int arg1, int arg2);[OperationContract]double Add(double arg1, double arg2);}
3.可以用OperationContract的Name屬性設置方法的別名

[ServiceContract]interface ICalculator{[OperationContract(Name = "AddInt")]int Add(int arg1, int arg2);[OperationContract(Name = "AddDouble")]double Add(double arg1, double arg2);}
這樣客戶端就會生成AddInt和AddDouble方法.客戶端會生成如下代碼

[ServiceContract]interface ICalculator{[OperationContract]int AddInt(int arg1, int arg2);[OperationContract]double AddDouble(double arg1, double arg2);}class CalculatorClient : ClientBase<ICalculator>, ICalculator{public int AddInt(int arg1, int arg2){return Channel.AddInt(arg1, arg2);}public double AddDouble(double arg1, double arg2){return Channel.AddDouble(arg1, arg2);}//Rest of the proxy}

最好是避免這種寫法，直接修改方法名

二.客戶端操作重載

也可以在客戶端指定別名

[ServiceContract]interface ICalculator{[OperationContract(Name = "AddInt")]int Add(int arg1, int arg2);[OperationContract(Name = "AddDouble")]double Add(double arg1, double arg2);}class CalculatorClient : ClientBase<ICalculator>, ICalculator{public int Add(int arg1, int arg2){return Channel.Add(arg1, arg2);}public double Add(double arg1, double arg2){return Channel.Add(arg1, arg2);}//Rest of the proxy}
