C# SDK, CIM - Exposing ReasonCode

[crmGuy]

I recently discovered that the ReasonCode was not properly exposed on in the C# SDK's version of a transaction response.  The fix ended up being a palm to forehead moment for me.  Here it is!

Let's take an overly simplified transaction request...

private void GetResponse(string profileID, string paymentProfileID, string shippingAddressID)
        {
            Order order = new Order(profileID, paymentProfileID, shippingAddressID);
            //Build the order

            var response = AuthAndCapture(order);
            string reasonCode = response.ReasonCode;  <<  IMPOSSIBLE!  :(
        }  

private IGatewayResponse AuthAndCapture(Order order)
        {
            var req = new createCustomerProfileTransactionRequest();
            var trans = new profileTransAuthCaptureType();
            //Build the request

            var response = (createCustomerProfileTransactionResponse)_gateway.Send(req);
            
            return new GatewayResponse(response.directResponse.Split(','));
        }

The response in GetResponse() will not contain contain the result code and result text, but not the reason code.  This works just fine if the transaction is successful, but quite a hassle if it is not.  

Open the GatewayResponse.cs class in the AIM > Responses directory of the SDK and insert the follwing property into the existing list: 

public string ReasonCode {
            get {
                return ParseResponse(2);
            }
        }

Next open the IGatewayResponse.cs interface in the same directory and add the following property:  

string ReasonCode { get; }

Now the GetResponse() method has access to the ReasonCode!  Huzzah!

private void GetResponse(string profileID, string paymentProfileID, string shippingAddressID)
        {
            Order order = new Order(profileID, paymentProfileID, shippingAddressID);
            //Build the order

            var response = AuthAndCapture(order);
            string reasonCode = response.ReasonCode;
        }
