How to mess up an array in C#?

Question

I have a question with the List<> datatype in C#. I have a List of colors (List<Color> colores) in a program that I am doing in Windows Forms, but I want that everytime that start the program this list mess up it of random form. I am searching a method as colores.Disort() but this doesn't exist.

Any ideas?

My array to disort is:

Color[] colores = new Color[] { 
    Color.FromArgb(128, 128, 255),
    Color.FromArgb(255, 128, 128),
    Color.FromArgb(255, 192, 128),
    Color.FromArgb(255, 255, 128),
    Color.FromArgb(255, 255, 128),
    Color.MediumPurple};

PD: I don't want a method of multiple lines, just a short method. The colors shouldn't repeat it.

Thanks you for your time!

i'm assuming that by "mess up it of random form", you mean to assign random values to each colour in the list? — absoluteAquarian, Oct 08 '18 at 13:40
You can write everything in one line if you find that more readable — Tim Schmelter, Oct 08 '18 at 13:40
Do you mean **shuffle**? https://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle — Dmitry Bychenko, Oct 08 '18 at 13:40

var rnd = new Random();
var randomColors = colores.OrderBy(color => rnd.Next());

Please consider reading SO Post about effectiveness of this method.

Is using Random and OrderBy a good shuffle algorithm?

This code is great but there is an inconvenient. The color repeat it. – calvin11 Oct 08 '18 at 13:48

It's not supposed to happen, pay attention that your example adds the same color twice... – MaxB Oct 08 '18 at 13:57
