C#如何getvalue函数值

RequestData调用： RequestData.PutValue(String key, String value)

ResponseData调用：ResponseData.GetValue(Key as String) As String

TypReq = Type.GetTypeFromProgID("BB.RequestData");
TypRes = Type.GetTypeFromProgID("BB.ResponseData");
TypMis = Type.GetTypeFromProgID("BB.MisPos");

            request = Activator.CreateInstance(TypReq);
            response = Activator.CreateInstance(TypRes);
            mispos = Activator.CreateInstance(TypMis);


            TypMis.InvokeMember("PutValue", BindingFlags.InvokeMethod, null, request, new Object[] { "CardType", "01" });
            TypMis.InvokeMember("PutValue", BindingFlags.InvokeMethod, null, request, new Object[] { "TransType", TransType });

            TypMis.InvokeMember("TransProcess", BindingFlags.InvokeMethod, null, mispos, new Object[] {request, response});
            Console.WriteLine("response");
                            现在无法打印出response 的值，即函数ResponseData的返回值

TypMis .GetMethod("PutValue").Invoke(mispos, new Object[] { "CardType", "01" })
