C#声明2D数组 [英] C# declaring a 2D array

问题描述

我正在尝试在C#中设置一个2d数组，作为一个迷宫来移动角色，我在初始化该数组时遇到了一些问题，我正在尝试执行以下操作

I am trying to setup a 2d array in C# to act as a maze to move a character around, I am having a few issues initialising the array, I am trying to do the below

但是InitialiseMaze方法表示未声明迷宫

but the InitialiseMaze method is saying the maze is not declared

任何人都可以建议

谢谢

推荐答案

除了变量声明之外，您不能像这样初始化数组.但是，更改很简单:

You can't initialize an array like that other than in a variable declaration. However, the change is simple:

maze = new int[,] { 
   // As before
};

助手:

• 看起来maze应该是 instance 变量，而不是静态变量.毕竟，您每次创建Maze
实例时都要对其进行初始化.
• 您无缘无故拥有终结器.在C#中很少需要(或确实建议)终结器

• It looks like maze should be an instance variable rather than a static variable. After all, you're initializing it each time you create an instance of Maze
• You have a finalizer for no reason. Finalizers are very rarely required (or indeed advisable) in C#
