I'm getting "exception has been thrown by the target of an invocation" while calling a wcf service method at the client side using reflection.
I'm getting the exception while invoking the method at the line:
object result = oMeth.Invoke(oProxy,@params);

Here is my service :

public string GetData(int value)
            return string.Format("You entered: {0}", value);

my client side code:

ChannelFactory<WcfService1.IService1> myFactory = default(ChannelFactory<WcfService1.IService1>);
            myFactory = new ChannelFactory<WcfService1.IService1>(new BasicHttpBinding(), "http://localhost:3250");
            object oProxy = myFactory.CreateChannel();           
            Type oType = oProxy.GetType();
            MethodInfo oMeth = oType.GetMethod("GetData");
            object[] @params = { 3 };
            object result = oMeth.Invoke(oProxy,@params);

Plz help if know the solution.

Thanks & Regards,

Take a look at this[^] and check if it will work on your side.

Solution 2

When the exception gets thrown, drill down into the innerexception details - there's more info there!

Either your service endpoint isn't using a BasicHttpBinding or your URL is wrong. I suspect the latter.

Your code works fine for me.
