C#Monogame - 带有2D数组的System.IndexOutOfRangeException

标签: c# arrays monogame

我遇到了C#的问题,每当我在其中一个类中运行Draw方法时,我会不断收到IndexOutOfRangeException。

我现在一直试图找出问题几个小时,但我还没有找到确切的问题,而且我还没能找到任何解决方案。 StackOverflow的。

我是C#的新手(我只学了3到4天),所以解决方案可能会非常明显。

Level.cs:

using Microsoft.Xna.Framework.Graphics;

namespace Game1 {
    class Level {
        public Tile[,] Tiles;

        public void Draw(SpriteBatch sb) {
            for (int x = 0; x < Tiles.GetLength(0); x++)
                for (int y = 0; x < Tiles.GetLength(1); y++)
                    if (Tiles[x, y] != null)
                        Tiles[x, y].Draw(sb, x, y);
        }

        public Level(int size) {
            Tiles = new Tile[size, size];
            for (int x = 0; x < size; x++)
                for (int y = 0; y < size; y++)
                    Tiles[x, y] = Tile.Tiles[0];
        }
    }
}

Tile.cs:

using System.Collections.Generic;

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;

namespace Game1 {
    class Tile {
        public static List<Tile> Tiles = new List<Tile>();

        Texture2D Image;

        public void Draw(SpriteBatch sb, int x, int y) {
            sb.Draw(this.Image, new Vector2(x * this.Image.Width, y * this.Image.Height), Color.White);
        }

        public Tile(Texture2D image) {
            this.Image = image;
            Tiles.Add(this);
        }
    }
}

尝试检查你的for循环中的y&lt; ...而不是x&lt; ...

编辑: - 更改以下方法以检查第一个(外部)循环中的namespace DrawShapes { class Rectangle : Shape { public int length; public int width; public Rectangle(int length, int width, string name) : base(name) { //this.angles = angles; this.length = length; this.width = width; } public override void DisplayArea() { Console.Write(name + "--"); Console.Write(length * width); } } class Triangle : Shape { // public int angles; public int width; public int height; public Triangle(int width, int height, string name) : base(name) { //this.angles = angles; this.width = width; this.height = height; } public override void DisplayArea() { Console.Write(name + "--"); Console.Write((width * height) / 2); } } class Circle : Shape { public int radius; public Circle(int radius, string name) : base(name) { this.radius = radius; } public override void DisplayArea() { Console.Write(name + "--"); Console.Write(3.22 * radius * radius); } } } 和第二个(内部)循环中的x

y

试试这个:

 public void Draw(SpriteBatch sb) {
        for (int x = 0; x < Tiles.GetLength(0)-1; x++)
            for (int y = 0; x < Tiles.GetLength(1)-1; y++)
                if (Tiles[x, y] != null)
                    Tiles[x, y].Draw(sb, x, y);
    }
