3. C# — Get Unique Characters in One Line

Want only distinct characters from a string?

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string text = "Mississippi";

        // Unique characters
        string unique = new string(text.Distinct().ToArray());

        Console.WriteLine(unique); // Misp
    }
}

✅ Cool because:

• Uses LINQ’s Distinct().

• Cleans up duplicates instantly.
