Question

Hello I am making a double buffer in C# and I need to find out a formula to plot the X and Y coordinates in my array. Currently I am using a loop to plot my X and Y but it takes along time to do it. (NOTE I CANNOT USE A MULTI DIMENSIONAL ARRAY!!!)

Answer 1

int[] buffer = new int[width * height];

void Plot(int x, int y, int color)
{
    buffer[y* width + x] = color;
}

EDIT

To plot longer blocks you could use the Array.Copy functions

If that is still too slow you could fallback to unsafe code to fill the array
