    Dictionary<string, object> res;
    string json;
    Dictionary<string, object> input;

    var method = proxyclient.GetMethod("ComplexInputTest");
    var request = method.CreateRequest();

    var argumant = method.GetArgumant("input1");
    var temp = argumant.Type.CreateComplexInstance();
    argumant.Type.GetPropery("Datetime").SetValue(temp, DateTime.Now);
    argumant.Type.GetPropery("INTValue").SetValue(temp, 0);
    argumant.Type.GetPropery("Value").SetValue(temp, false);
    argumant.SetValue(request, temp);


    argumant = method.GetArgumant("input2");
    temp = argumant.Type.CreateComplexInstance();
    argumant.Type.GetPropery("Name").SetValue(temp, "Hello");
    argumant.SetValue(request, temp);

    res = proxyclient.Call(request);
    json = Newtonsoft.Json.JsonConvert.SerializeObject(res);
    Console.WriteLine(json);
    Console.WriteLine("----------------------------");
