C# - How to convert 10 bytes to unsigned long
- by Justin
Hey,
I have 10 bytes - 4 bytes of low order, 4 bytes of high order, 2 bytes of highest order - that I need to convert to an unsigned long. I've tried a couple different methods but neither of them worked:
Try #1:
var id = BitConverter.ToUInt64(buffer, 0);
Try #2:
var id = GetID(buffer, 0);
long GetID(byte[] buffer, int startIndex)
{
var lowOrderUnitId = BitConverter.ToUInt32(buffer, startIndex);
var highOrderUnitId = BitConverter.ToUInt32(buffer, startIndex + 4);
var highestOrderUnitId = BitConverter.ToUInt16(buffer, startIndex + 8);
return lowOrderUnitId + (highOrderUnitId * 100000000) + (highestOrderUnitId * 10000000000000000);
}
Any help would be appreciated, thanks!
