How to sort string based on substring with C#?

December 23, 2021

I have a string

string myStr = "*20@Apple#*10@Banana#*-5@Orange#*8@Cherries#";

I want an array that contains only fruit names from this string, but it should be sorted based on a value that is associated with it.

For example, in this string

Apple => 20
Banana => 10
Orange => -5
Cherries => 8

I want this this array as a result

Orange, cherries, Banana, Apple

Thank You!

>Solution :

var input = "*20@Apple#*10@Banana#*-5@Orange#*8@Cherries#";

var result = input
      .Split(new []{'#','*' }, StringSplitOptions.RemoveEmptyEntries)
      .Select(x => x.Split('@'))
      .Select(x => (Rank : int.Parse(x[0]), Value : x[1]))
      .OrderBy(x => x.Rank)
      .Select(x => x.Value)
      .ToArray();

Console.WriteLine(string.Join(", ",result));

Output
