仍然可以从 C# 中的另一个 class 访问私有变量

Question

我有一个 .cs 文件，如下所示

namespace TarkovMapper.ClassObjects
{
    class PointCloud_Object
    {
        public void AddPoint(PointEntry_Object point)
        {
            PointLayer pointLayer = LoadPointLayer(path);
            pointLayer.Points[point.Location_x,point.Location_y]++;
        }
        private PointLayer LoadPointLayer(string path)
        {
            if (!File.Exists(path)) return new PointLayer(this.Width, this.Height);
            Stream s = File.OpenRead(path);
            BinaryFormatter b = new BinaryFormatter();
            PointLayer returnObject = (PointLayer) b.Deserialize(s);
            s.Close();
            return returnObject;
        }
    }
    [Serializable]
    class PointLayer
    {
        public PointLayer(int width, int height)
        {
            this.Points = new int[width, height];
        }
        public int[,] Points { get; private set; } // <- private set!!!
        public int Maximum { get; private set; }
    }
}

我的问题是关于 class PointLayer 中的变量“Points”。尽管我有修改器 private set; PointCloudObject 中的以下行没有问题 pointLayer.Points[point.Location_x,point.Location_y]++;.

这是为什么？

Answer 1

修饰符指的是 Points 数组，而不是数组的各个元素。 PointCloud_Object class 无法将新数组分配给 PointLayer.Points 变量，但它可以操作单个数组元素。

仍然可以从 C# 中的另一个 class 访问私有变量

private variable is still accessible from another class in C#

class

variables

set

private
