If I paste the following into a URL:

http://webservices.amazon.com/onca/xml?Service=AWSECommerceService&AWSAccessKeyId=AKIAJGNPAX3WUT652ZDQ&Operation=ItemSearch&ItemId=9780321321831&SearchIndex=Books&ResponseGroup=Large&Keywords=9780321321831

what gets returned is an XML document with the information desired.


That's fine.


But what I am trying to figure-out how to do is the EXACT SAME THING in the C# code behind.


Can anyone help me?

Please provide sample (  C# !!!!  )  source code.

I also need someone to help me debug.

There is no ECommerce REST Interface?

This is for S3.

Does it matter?

Here was my eventual solution:

    private void GetBookInfoFromAmazon(string ISBN)
    {
      AmazonECommerceService.ItemSearch iSearch = new AmazonECommerceService.ItemSearch();

      iSearch.AWSAccessKeyId = "AKIAJGNPAX3WUT652ZDQ";

      AmazonECommerceService.AWSECommerceServicePortTypeClient aecs = new AmazonECommerceService.AWSECommerceServicePortTypeClient();

      AmazonECommerceService.ItemSearchResponse isr = new NOTLWONK.AmazonECommerceService.ItemSearchResponse();

      AmazonECommerceService.ItemSearchRequest isreq = new NOTLWONK.AmazonECommerceService.ItemSearchRequest();

      isreq.SearchIndex = "Books";
      isreq.Keywords = ISBN;

      string[] rg = { "Large" };
      isreq.ResponseGroup = rg;

      iSearch.Request = new AmazonECommerceService.ItemSearchRequest[] { isreq };

      isr = aecs.ItemSearch(iSearch);
    }
