No, there won't be any measurable benefit.

This is premature micro-optimization at its worst.

In addition, in order to do this, you'll need to pin the array using the fixed keyword, which is orders of magnitude slower than your existing code.

No, it won't be any faster.

This is premature micro-optimization at its worst.

In fact, it will be orders of magnitude slower, since you'll need to pin the array (using the fixed keyword) in order to get a pointer to it.

No, there won't be any measurable benefit.

This is premature micro-optimization at its worst.

In addition, you can't even do it:

• Those are properties, not fields
• Even had they been fields, a field is a managed reference, not a pointer.
  You cannot use it the way you use a pointer, even in unsafe code.
