如何在不对名称进行硬编码的情况下将接口类型传递给ChannelFactory [英] How to pass Interface type to ChannelFactory without hardcoding the name

问题描述

我使用反射调用WCF服务.我在使用ChannelFactory，绑定和端点地址创建代理的地方.
让我们认为我的服务合同"名称为ISeravice1.
我正在创建代理并以这种方式调用特定方法:

Hi,
I calling a WCF Service using reflections . Where I''m creating a Proxy by using ChannelFactory ,binding and endpoint address.
Let us think that My ServiceContract Name is ISeravice1.
I''m creating a Proxy and calling a specific method in this way:

using (ChannelFactory<T> cf = new ChannelFactory<T>(binding, uri))
            {
                object oProxy = cf.CreateChannel();
                Type oType = oProxy.GetType();
                MethodInfo oMeth = oType.GetMethod(method);
                oMeth.Invoke(oProxy, args);
            }

在上面的代码中，我需要通过< T>作为我的ServiceContact，即IService1.
如果我有很多服务合同，则需要全部指定，因此我需要删除服务合同名称的硬编码.
问候，
Ramana

In the above code I need to pass <T> as my ServiceContact that is IService1.
If I have many Service Contracts then I need to specify all , so I need to remove hardcoding of name of Service Contract.
Regards,
Ramana

推荐答案

由于您始终在使用反射，因此可以使用反射实例化通用ChannelFactory类.

Since you''re using reflection anyways, you could instantiate the generic ChannelFactory class using reflection.

public static object CreateGeneric(Type generic, Type innerType, params object[] args)
{
    System.Type specificType = generic.MakeGenericType(new System.Type[] { innerType });
    return Activator.CreateInstance(specificType, args);
}

var contract = typeof(ICoolWebService); // or whatever
var cf = CreateGeneric(typeof(ChannelFactory), contract);
