Is there a simple way that I can sort characters in a string in alphabetical order

Question

I have strings like this:

var a = "ABCFE";

Is there a simple way that I can sort this string into:

ABCEF

Thanks

Answer 1

You can use LINQ:

String.Concat(str.OrderBy(c => c))

If you want to remove duplicates, add .Distinct().

Answer 2

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}
