c# - how to create an array without objects initialized to null or 0?

Question

byte[] buffer = new byte[500000];

initializes buffer with 0 values. As it is a buffer, I dont want any initialization, is it possible in C# as in C?

Answer 1

I don't think it is possible... Even FormatterServices.GetUninitializedObject that doesn't run constructors:

Because the new instance of the object is initialized to zero and no constructors are run, the object might not represent a state that is regarded as valid by that object.

Note that if you want unmanaged (memory taken from the OS that isn't GC-managed), that can be allocated without zeroing it, but it wouldn't be a byte[].
