LINQ: Get first character of each string in an array

Question

Consider a string array shaped like this:

  string[] someName = new string[] { "First", "MiddleName", "LastName" };

The requirement is to get the first character from each element in the array.

i.e.

FML

Previously have tried:

string initials = string.Concat(someName.Select(x => x[0]));

Question: What LINQ query would you write to concatenate all the name contained in the string array to give the initials?

Answer 1

try this:

string shortName = new string(someName.Select(s => s[0]).ToArray());

or, if you suspect that any of the strings might be empty or so:

string shortName = new string(someName.Where(s => !string.IsNullOrEmpty(s))
                                      .Select(s => s[0]).ToArray());
