var zip = testNames.Zip(testNumbers, (code, state) => code + ": " + state);

returns an IEnumerable of strings, how would I get IEnumerable string string?

  • Use backticks to format code. What type do you want? – SLaks Jun 17 '18 at 02:00
  • Make testNames a List() object. Sometimes testNames.AsEnumerable().Zip will work. Sometimes using testNames.Cast().Zip will solve issue. – jdweng Jun 17 '18 at 02:08

    What do you mean by `IEnumberable string string`? That's not a valid type. Do you mean `IEnumerable<>` or `IEnumerable<(string, string)>`? – Enigmativity Jun 17 '18 at 02:18

Here are you two choices, based on what you've given us in your question:

var testNames = new [] { "A", "B" };
var testNumbers = new [] { 1, 2 };

var zip1 = testNames.Zip(testNumbers, (code, state) => new { code, state });

var zip2 = testNames.Zip(testNumbers, (code, state) => (code, state));

Both are valid C#.

Based on reading your previous question you should need to get in to this .Zip scenario. You should be able to read your original data in a single query. My answer shows you how.
