有没有一种简单的方法可以按字母顺序对字符串中的字符进行排序

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);
}

Answer 3

new string (str.OrderBy(c => c).ToArray())

Answer 4

You can use this

string x = "ABCGH"

char[] charX = x.ToCharArray();

Array.Sort(charX);

This will sort your string.

Answer 5

It is another.You can use SortedSet:

var letters = new SortedSet<char> ("ABCFE");
foreach (char c in letters) Console.Write (c); // ABCEF

Answer 6

var sortedString1 = string.Join("", str1.OrderBy(x => x).ToArray());

This will return a sorted string
