how to convert a value type to byte[] in C#?

Question

I want to do the equivalent of this: ``` byte[] byteArray; enum commands : byte {one, two}; commands content = one; byteArray = (byte*)&content; ``` yes, it's a byte now, but consider I want to change it in the future? how do I make byteArray contain content? (I don't care to copy it).

Accepted Answer

The BitConverter class might be what you are looking for. Example:

```
int input = 123;
byte[] output = BitConverter.GetBytes(input);
```

If your enum was known to be an Int32 derived type, you could simply cast its values first:

```
BitConverter.GetBytes((int)commands.one);
```
