Question

I am trying to search within a string for a specific value.

What I want to do is SPLIT the string and look at each value.
If the mySearch.EQUALS(split-string-value) then return the record(s) in a ToList().

This is my code.. It returns ZERO RECORDS

// user search for sku = "2012"
// p.productMatch in DB = "2012,2012L,2012LR,2011"

var result = ctx.Products
 .Where(p => p.clientID == Config.ClientID)
 .Where(p => p.productMatch.Contains(sku))
 .Select(v => new ProductView
     {
         productID = v.productID,
         productMatch = v.productMatch,
         productSKU = v.productSKU
     }).ToList();


var results = from w in result
          where w.productMatch.Split(',').Equals(sku)
          select w;


return results.ToList();

Answer 1

At the moment, in your where w.productMatch.Split(',').Equals(sku) line you compare result of Split() (which is array of strings) with single string sku. For obvious reasons this fails. Simply change it to:

where w.productMatch.Split(',').Contains(sku)
