c# - int[] 是引用类型还是值类型？

Question

我知道 int 是值类型，但什么是值类型数组？引用类型？值类型？我想将一个数组传递给一个函数来检查一些东西。我应该只传递数组，因为它只会传递它的引用，还是应该将它作为 ref 传递？

Answer 1

Arrays are mechanisms that allow you to treat several items as a single collection. The Microsoft® .NET Common Language Runtime (CLR) supports single-dimensional arrays, multidimensional arrays, and jagged arrays (arrays of arrays). All array types are implicitly derived from System.Array, which itself is derived from System.Object. This means that all arrays are always reference types which are allocated on the managed heap, and your app's variable contains a reference to the array and not the array itself.
