Question

byte[] bytes = new byte[100];
bytes.Initialize();

What’s the default values in above bytes byte array after the Initialize() called? all null\0?

Answer 1

It has no effect.

byte[] test = new byte[100];
test[1] = 4;
test.Initialize();
Console.WriteLine(test[1]);

will print 4. The effect of Initialize is not (as may perhaps have been more sensible) to return default(T) but to call new T(). In cases where this does not work, it fails silently.
