本文对比了Array.ConstrainedCopy和Buffer.BlockCopy两种方法在复制数组时的不同表现，强调了Array.ConstrainedCopy在验证数组并确保复制操作可靠性方面的优势。它通过实例说明了如何在不同场景下选择合适的方法来避免潜在错误。

Buffer.BlockCopy更高效，但是仅限于primitive类型

Array.ConstrainedCopy validates arrays before it copies them. The regular Array.Copy method will silently copy a byte array to an int array. The Array.ConstrainedCopy method instead throws an exception. This can improve reliability.

Copies a range of elements from an Array starting at the specified source index and pastes them to another Array starting at the specified destination index. Guarantees that all changes are undone if the copy does not succeed completely.
