C#: Why doesn't Initialize work with a Byte-Array?

Question

I declare a Byte-Array like this:

Byte[] b = new Byte[10];

and assign some values:

for (int i=0; i<b.Length; i++)
{
    b[i] = 1;
}

Now I want to zero the array again and call:

b.Initialize();

which doesn't work. The array remains unchanged. Isn't b a value-type array?

Array.Clear is probably what you're looking for

See MSDN:

Caution

You can use this method only on value types that have constructors; however, value types that are native to C# do not have constructors.

byte is native.

Perhaps most telling from the MSDN article: "This method is designed to help compilers support value-type arrays; most users do not need this method."

@Marc: Right, I didn't read the caution note in MSDN carefully enough.

@Ramhound no, it will do no such thing. That creates a new array ; it resets nothing except for the variable. It absolutely does not reinitialize the array.

Is the method intended for use with languages that allow value types to have non-trivial default constructors?
