C# convert from uint[] to byte[]

Question

This might be a simple one, but I can\'t seem to find an easy way to do it. I need to save an array of 84 uint\'s into an SQL database\'s BINARY field. So I\'m using the fol

Answer 1

If you need all the bits from each uint, you're gonna to have to make an appropriately sized byte[] and copy each uint into the four bytes it represents.

Something like this ought to work:

uint[] uintArray;

//I need to convert from uint[] to byte[]
byte[] byteArray = new byte[uintArray.Length * sizeof(uint)];
for (int i = 0; i < uintArray.Length; i++)
{
    byte[] barray = System.BitConverter.GetBytes(uintArray[i]);
    for (int j = 0; j < barray.Length; j++)
    {
          byteArray[i * sizeof(uint) + j] = barray[j];
    }
}
cmd.Parameters.Add("@myBindaryData", SqlDbType.Binary).Value = byteArray;
