Empty elements in C# byte array

Byte[] array = new Byte[64];

Array.Clear(array, 0, array.Length);

I tried endlessly to use Array.Clear() to clear a large byte[] that I have in my program. It would NEVER work. I do not know why. But I found a solution:

array = new byte[0];

Use the "clear" method on Array.

 Array.Clear(array , 0, array.Length);
