索引超出数组（C＃）的范围

Question

我在这行上看到“索引在数组的边界之外”，这是怎么回事？

Kort[x, y] = Sort[x] + Valor[y] + " ";    

以下是完整的代码：

    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;

    namespace uppgift_13
    {
        public partial class Form1 : Form
        {
            string[,] Kort = new string[4,13];
            string[] Valor = new string[13];
            string[] Sort = new string[4];
            int x, y;


            public Form1()
            {
                InitializeComponent();
            }

            private void Form1_Load(object sender, EventArgs e)
            {
                Valor[1] = "2";
                Valor[2] = "3";
                Valor[3] = "4";
                Valor[4] = "5";
                Valor[5] = "6";
                Valor[6] = "7";
                Valor[7] = "8";
                Valor[8] = "9";
                Valor[9] = "10";
                Valor[10] = "Knekt";
                Valor[11] = "Dam";
                Valor[12] = "Kung";
                Valor[13] = "Ess";

                Sort[1] = "H";
                Sort[2] = "R";
                Sort[3] = "S";
                Sort[4] = "K";
            }


            private void LaddaKort()
            {
                for (this.x = 1; this.x <= 4; this.x++)
                {
                    for (this.y = 1; this.y <= 13; this.y++)
                    {
                        Kort[x, y] = Sort[x] + Valor[y] + " ";
                    }
                }
            }

            private void SkrivKort()
            {
                for (this.x = 1; this.x <= 4; this.x++)
                {
                    for (this.y = 1; this.y <= 13; this.y++)
                    {
                        richTextBox1.AppendText(Kort[x, y]);
                    }
                }
            }

            private void button1_Click(object sender, EventArgs e)
            {
                LaddaKort();
                SkrivKort();
            }

        }
    }

Answer 1

从0而不是1开始进行数组访问

因此，更改为：

private void Form1_Load(object sender, EventArgs e)
            {
                Valor[0] = "2";
                Valor[1] = "3";
                Valor[2] = "4";
                Valor[3] = "5";
                Valor[4] = "6";
                Valor[5] = "7";
                Valor[6] = "8";
                Valor[7] = "9";
                Valor[8] = "10";
                Valor[9] = "Knekt";
                Valor[10] = "Dam";
                Valor[11] = "Kung";
                Valor[12] = "Ess";

                Sort[0] = "H";
                Sort[1] = "R";
                Sort[2] = "S";
                Sort[3] = "K";
            }

同样，从0而不是1开始任何循环，并让条件小于长度，直到相等为止。 更像：

for (int i=0; i < theArray.Length; i++)

Answer 2

在C＃数组中从零开始...

看看Kevek回答您的好处：

这个：

for (this.x = 1; this.x <= 4; this.x++)
{
  for (this.y = 1; this.y <= 13; this.y++)
  ...

应该：

for (this.x = 0; this.x < 4; this.x++)
{
  for (this.y = 0; this.y < 13; this.y++)
  ...

Answer 3

Sort是数组0..3，Valor是0..12。 因此，您不能使用Sort [4]和Valor [13]。
