Code to convert from 8-bit integers to 16 bit integers and vice versa?

2009-10-16T10:14:29Z

I'm looking for a simple pair of functions that will convert a pair of 8-bit integers into a single 16-bit integer type and vice versa. Does anyone know of one for .NET?

[someone with more rep: please add the "c#" tag?]

Here's at least one that ought do do nicely:

/// <summary>
/// converts a short into two component bytes.
/// </summary>
/// <param name="input">the short to break down.</param>
/// <param name="high">the high byte output of the function.</param>
/// <param name="low">the low byte output of the function.</param>
public static void FromShort(short input, out byte high, out byte low)
{
    high = (byte)(input >> 8);
    low = (byte)(input - ((input >> 8) << 8));
}

/// <summary>
/// converts 2 component bytes into a short.
/// </summary>
/// <param name="high">the high byte of a short.</param>
/// <param name="low">the low byte of a short.</param>
/// <returns>the short that the two bytes represented.</returns>
public static short ToShort(byte high, byte low)
{
    return (short)((short)low + ((short)high << 8));
}

Assuming jQuery syntax is similar to c#, so domething like this:

static int clampToRange(int value, int min, int max)
{
    if (value < min) { return min; }
    if (value > max) { return max; }
    return value;
}

Then all you need to do is this in your code:

level = clampToRange(level, 0, maxLevel);
