Hello, Ole!

O> How do I compare two byte arrays in a if statement?

You have to loop through array comparing every item.

Smth like

bool IsEqual(byte[] arr1, byte[] arr2)
{
if ( arr1 == null || arr2 == null )
return false;

if ( arr1.Length != arr2.Length )
return false;

//and here is the check loop
for(int i = 0; i < arr1.Length; i++ )
{
if ( arr1[i] != arr2[i] )
return false;
}
return true;
}
