锯齿数组类型的属性 [英] Jagged Array typed Properties

问题描述

说我有一个像这样的财产:

Say I have a property like this:

public int[] MyProperty
{
    get;
    set;
}

调用代码可以自由更改数组的值，也可以替换数组本身.可以通过隐藏设置器来轻松地防止这种情况发生，就像这样:

The calling code is free to change the values of the array, but also to replace the array itself. This can easily be prevented by hiding the setter, like so:

public int[] MyProperty
{
    get;
    private set;
}

这允许调用代码更改值，但不能将数组更改为其他数组，也不能更改大小.

This allows the calling code to change the values, but it can't change the array to a different one, or change the size.

此模式适用于多维数组，但不适用于锯齿状数组.如果我有这个话:

This pattern works with multidimensional arrays, but not jagged arrays. If I have this:

public int[][] MyProperty
{
    get;
    private set;
}

不能修改主数组，但是可以修改子数组.如果我想将子数组设置为只读，以便调用代码可以更改元素，但不能更改数组怎么办?

The main array can't be modified, but the child arrays can. What if I want to make the child arrays readonly, so that the calling code can change the elements, but not the arrays?

如何仅使锯齿状数组的元素可修改?这包括3D及更高版本.

How can I make only the elements of jagged arrays modifiable? This includes 3D and higher.

推荐答案

您应该使用

You should use a ReadOnlyCollection<int[]>.
