Convert integer to byte array

Question

I am having a hard time trying to perform what should be a simple conversion from an integer to a byte array.

I feel this must be simple, even trivial, but cannot get it (so if anyone know the right "name" for this operation, please tell me). Also, I couldn't find a better question title, but I feel it's a bit vague (feel free to edit).

What I want:

byte[] result = MagicConverter.Convert(336);
// now result should be {0, 0, 1, 80}

The result of converting 336 should be 1, 80 because that is the decomposition in base 256, that is, 1*256 + 80 = 336.

My codebase contain a lot of bitshifting stuff to perform similar tasks, but I think I'm not quite inderstanding this bitshifting thing yet.

Answer 1

BitConverter.GetBytes(366); 

应该做到的。

Answer 2

您正在寻找的是BitConverter.GetBytes（） ：

byte[] result = BitConverter.GetBytes(366);

Answer 3

您可以使用BitConverter.GetBytes()函数执行此操作。
