Error double [,] to image

Question

I am trying to use this example (see first answer): C# convert a 2D double array to and greyscale image I am getting this error: https://i.imgsafe.org/2226c81bdc.png

I am using:

using System;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Diagnostics;
using System.Drawing;
using System.Drawing.Imaging;
using System.Linq;

Without seeing your code how can we help you? Please show code in your question, screenshots of code are not helpful. — maccettura, Feb 13 '17 at 21:22

Also see this [answer](http://stackoverflow.com/a/15395139/5095502). The example you are using is incomplete, that person must be using an extension method such as the one I just linked, or they typed the code without actually testing it. — Quantic, Feb 13 '17 at 21:24

My guess would be that the user who answered the question created an extension method similar to this:

public static double Min(this double[,] values)
{
    double min = double.MaxValue;

    foreach (var value in values)
    {
        if (value < min)
        {
            min = value;
        }
    }

    return min;
}

Plus a similar method for Max()

EDIT: The foreach loop could also be replaced with the data.Cast().Min() call as suggested by @JerryGoyal
