    GetPixel Color Value

    Im using the BitMap object to get a pixel color.
    Code:
    BitMap.GetPixel
    No Im not sure as to how to convert that to a string or to view that in any. The only thing I want to do is get the colour value of the Bitmap pixel. As in black would be 255 and white would be 0. Anyone know how to do this?

    GetPixel returns a color object doesn't it? With that color you should have the following methods available to you :

    GetRed()
    GetGreen()
    GetBlue()

    From MSDN:

    A Color object stores a 32-bit value that represents a color. The color value contains four, 8-bit components: alpha, red, green, and blue. The first 8 bits (the most significant) contain the alpha component, the next 8 bits contain the red component, the next 8 bits contain the green component, and the next 8 bits (the least significant) contain the blue component. The 32-bit value is stored in a variable of type ARGB.
