See more: C# WCF reflection
Hi,
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,
Ramana

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

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.
