How to get MD5 Hash in RelayReponse page for validating

[prophet_quest]

Hi Experts,

I am new comer in Authorize.net Comminity so I have a question that I want to get the MD5 Hash for validating (Using the MD5 Hash feature). My project is written by C# ASP.NET (dont use MVC framework at all) I try to find in documents but no luck because it is written for MVC project. I am using DPM method to test

Any help is very appriciated

Thank you all in advance,

Binh Duong

Thanks Raynor for your answer, I found that code snippet below

var response = new AuthorizeNet.SIMResponse(this.Request.Form);
var isValid = response.Validate("YOUR_MERCHANT_HASH_CODE", "YOUR_APILOGIN");

but I have not tested yet, anyway thank you so much
