Randomizing a string [duplicate]

Answer 1

Randomize method (from another SO question):

public static T[] Randomize<T>(T[] source)
{
    List<T> randomized = new List<T>();
    List<T> original = new List<T>(source);
    Random r = new Random();
    for (int size = original.Count; size > 0; size--)
    {
        int index = r.Next(size);
        randomized.Add(original[index]);
        original[index] = original[size - 1];
    }
    return randomized.ToArray();
}

And usage:

string text = "Line";

string randomized = new string(Randomize(text.ToCharArray()));

Answer 2

Random rand = new Random();
var output = new string(input.OrderBy(x => rand.Next()).ToArray());
