Question

Besides using a loop. An int array can be initialized with 0s easy like arr = Enumerable.Range(0, 100).Select(i => new int[100]).ToArray();.

Is there a way I can initialize a string or char array in a similar fashion?

Answer 1

I think you’re looking for:

string[] arrayOfStringZeros = Enumerable.Range(0, 100)
                                        .Select(i => "0")
                                        .ToArray();


char[] arrayOfCharZeros = Enumerable.Range(0, 100)
                                   .Select(i => '0')
                                   .ToArray();

Updated

char[][] jaggedOfCharZeros = Enumerable.Range(0, 100)
                                       .Select(i => Enumerable.Range(0, 100)
                                                              .Select(j => '0')
                                                              .ToArray())
                                       .ToArray();

Actually it would probably be slightly more efficient to do:

char[] initZeros = Enumerable.Range(0, 100)
                             .Select(i => '0')
                             .ToArray();


char[][] jaggedOfCharZeros = Enumerable.Range(0, 100)
                                       .Select(i => (char[])initZeros.Clone())
                                       .ToArray();
