Array.ConstrainedCopy kan kun fungere på arraytyper, der er beviseligt kompatible uden nogen form for indpakning, udpakning, udvidelse eller konvertering af hvert arrayelement. Skift arraytyperne (dvs. kopier en Derived[] til en Base[]), eller brug en afhjælpningsstrategi i CER for Array.Copys mindre effektive pålidelighedskontrakt, f.eks. kloning af arrayet eller bortskaffelse af det potentielt beskadigede destinationsarray.

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.
