Array.ConstrainedCopy 將只能用於不需透過每個陣列元素 Boxing、Unboxing、擴展或轉換的任何形式即可證明相容的陣列型別。請變更您的陣列型別 (例如，通常可以複製 Derived[] 至 Base[])，或針對較不可靠的 Array.Copy 合約使用 CER 中的安全防護策略，例如，複製陣列，或丟棄可能損毀的目的陣列。

Array.ConstrainedCopy will only work on array types that are provably compatible, without any form of boxing, unboxing, widening, or casting of each array element. Change the array types (i.e., copy a Derived[] to a Base[]), or use a mitigation strategy in the CER for Array.Copy's less powerful reliability contract, such as cloning the array or throwing away the potentially corrupt destination array.
