c# - LINQ "zip" in String Array -

Say there are two arrays:

  string [] title = {"one" two three four"}; String [] user = {"rob", "", "john", ""};  

I have to filter the array given above when the user is empty, then join two or zip together in two. The final output should be:

  {"one: rob", "three: John"}  

How can LINQ be used?

It seems that you really want to "zip" data together (not to add) I.e. matches match; Is that right? If so, then simply:

  var qry = by title. Zip (user, (t, u) = & gt; new {title = t, user = u}) where! String Select the IsNullOrEmpty (row.User) row. Title + ":" + row.User; Foreach (string as in curie) console Limit (s); Using  

zip operation:
