Eligibility Benefit Inquiry and Response (270/271)

Hi All,
I want to develop below features :
  1. Create 270 Request which is byte encoded and a web service method is called to send the request.
  2. Parse 271 Response which the web service responds to the 270 request stating the error if there is in the request and the 271 response if the request is error free
  3. The 271 response is byte decoded and parsed to display the eligibility information on the web page
Can somebody help me on this? Mainly on decoding 271 response part....

Were you able to use this X12 Parser for your needs?

I see Create270Test in C:\Projects\OopFactory\src\trunk\tests\OopFactory.X12.Tests.Unit\DocumentationCodeSamples\X12InterchangeModel\ReadingAnExistingX12File.cs

How did you create your 270 request?

Wow - I'll review this and see how it matches up. We just bought the 5010 schema, but I assume that you've already validated against that. I'll need to update areas for my trading partner details, and it should be ok... I'll let you know.

Thank you!
