???? 現(xiàn)網(wǎng)上關(guān)于WCF所謂是很多,但好書很少.Programming WCF Services 應(yīng)該算是一本非常好的書。結(jié)合書和代碼總結(jié)一下.

一.服務(wù)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(wù)契約,WSDL規(guī)定方法不可重載

以下定義是錯(cuò)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(shè)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(huì)生成AddInt和AddDouble方法.客戶端會(huì)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}
