Value Type Conversion to Array

[David Kyle]

Just wondering if there's a quick way to convert types. I quite often have
things like an int that i want to convert the type to a byte array of length
4.

I guess the only way to do it is using unsafe code but even when doing that
I still have to copy the information to the array.

//this is what I would like to make work
int myInt = 244;
byte[] intAsBytes;

unsafe {
intAsBytes = &myInt;
}

//this is what I have to do
int myInt = 1;
byte[] intAsBytes = new byte[4];

unsafe {
byte* pointer = (byte*)&myInt;
for (int i = 0; i < 4; i++)
intAsBytes = *pointer++;
}

Yes, David. Use:

byte[] bytes = BitConverter.GetBytes(myInt);

HTH,

Awesome! Works like a charm! Thanks!

Yes, David. Use:

byte[] bytes = BitConverter.GetBytes(myInt);
