Question

我一直在尝试创建一个结构，然后使用该结构来创建一个2D数组，但我不断收到关于该类型的错误（无法将类型＆＃39; int＆＃39;转换为Point）。这是我的代码：

public struct Point
{
    public int x, y;
};

static void Main(string[] args)
{
    Point[,] points = { { 0, 0 }, { 1, 0 }, { 2, 1 }, { 1, 2 }, { 0, 2 } };
}

我有什么想法可以解决这个问题？我对编程比较陌生，需要一些指导：）

您似乎正在尝试创建Point的良好旧 1D 数组：

Point[] points = new Point[] {
  new Point() {x = 0, y = 0 },
  new Point() {x = 1, y = 0 }, 
  new Point() {x = 2, y = 1 }, 
  new Point() {x = 1, y = 2 }, 
  new Point() {x = 0, y = 2 },
};

如果您不想成为罗嗦，可以稍微修改Point：

public struct Point {
  public Point(int x, int y) {
    X = x;
    Y = y;    
  }

  //DONE: Exposing fields is a bad practice; converted to property
  //DONE: struct are often immutable (private set) 
  public int X {get; private set;}
  public int Y {get; private set;}
}

然后你可以做

Point[] points = new Point[] {
  new Point(0, 0),
  new Point(1, 0), 
  new Point(2, 1), 
  new Point(1, 2), 
  new Point(0, 2),
};

从结构创建2D数组时出错
