WCF“重载”方法的最佳实践

What is the best practice for emulating overloaded methods over WCF?

在WCF上模拟重载方法的最佳实践是什么？

Typically I might write an interface like this

通常我可能会编写这样的界面

interface IInterface 
{
    MyType ReadMyType(int id);
    IEnumerable<MyType> ReadMyType(String name);
    IEnumerable<MyType> ReadMyType(String name, int maxResults);    
}

What would this interface look like after you converted it to WCF?

将此接口转换为WCF后，该界面会是什么样子？

You can leave it like that if you like. Just use the name property of the OperationContract attribute.

如果你愿意，你可以这样离开。只需使用OperationContract属性的name属性即可。

[ServiceContract]
interface IInterface 
{
    MyType ReadMyType(int id);
    [OperationContract(Name= "Foo")]
    IEnumerable<MyType> ReadMyType(String name);
    [OperationContract(Name= "Bar")]
    IEnumerable<MyType> ReadMyType(String name, int maxResults);    
}

As mwilson already said - WCF doesn't allow methods to have the same name in the service definition (the WSDL).

正如mwilson所说 - WCF不允许方法在服务定义（WSDL）中具有相同的名称。

If you have two or more (overloaded) methods with the same name in .NET, you need to disambiguate them for the WCF service definition by specifying a Name= on the [OperationContract] attribute for each method.

如果在.NET中有两个或多个（重载）方法具有相同的名称，则需要通过在每个方法的[OperationContract]属性上指定Name =来为WCF服务定义消除歧义。

Remember: WCF is not .NET (or not .NET alone) - it's an interoperable standard, and the WSDL standard does not currently support method overloading - each method must be uniquely identifyable by name.

记住：WCF不是.NET（或者不是.NET） - 它是一个可互操作的标准，WSDL标准目前不支持方法重载 - 每个方法必须按名称唯一标识。
