Get ServiceContract Methods from WCF

Question

I want to list all methods from a WCF service that has the attribute "OperationContractAttribute"

For that, I use the following code:

var service = assembly.GetType(typeName);
        if (service == null)
            return webMethodsInfo;
        var methodsInfo = service.GetMethods();
        webMethods = methodsInfo.Where(method => method.GetCustomAttributes
             (typeof(OperationContractAttribute), true).Any()).ToList();

So, the OperationContractAttribute is specified in the interface (IClassA) and when I try to search this method attribute in the ClassA class, it can't find it however I specified the flag true for method GetCustomAttributes for searching to ancestors

May this help you LINK to similar Q/A http://stackoverflow.com/questions/2720617/how-to-get-all-methods-from-wcf-service — Milan Raval, Jan 30 '13 at 10:11
No, because I need ONLY OperationContract methods and not all methods (the solution from your link list all methods (including ToString, GetHashCode and so on...)) — Sergiu, Jan 30 '13 at 10:19

This will do

 MethodInfo[] methods = typeof(ITimeService).GetMethods();

            foreach (var method in methods)
            {
                if (((System.Attribute)(method.GetCustomAttributes(true)[0])).TypeId.ToString() == "System.ServiceModel.OperationContractAttribute")
                {                 
                    string methodName = method.Name;
                }
            }

What if a method has more than one attribute or does not have any at all? – DarkWanderer Jan 30 '13 at 11:37
it should be handled in the if : if(method.GetCustomAttributes(true).Any(attrib => ((System.Attribute)attrib).TypeId.ToString() == "System.ServiceModel.OperationContractAttribute")) – Milan Raval Jan 30 '13 at 11:58

webMethods = service.GetInterface(serviceContract).GetMethods().Where(
    method => method.GetCustomAttributes
      (typeof(OperationContractAttribute)).Any())
      .ToList();
