索引超出了数组的边界(c#)

本文关键字：边界 数组 索引 | 更新日期: 2023-09-27 18:07:48

我得到"索引是在数组的边界之外"这一行，怎么了?

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

下面是完整的代码:

    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();
            }
        }
    }

索引超出了数组的边界(c#)

从0开始数组访问，而不是1

那么，改成:

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开始任何循环，而不是从1开始。并使条件小于长度，直到相等。更像:

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

在c#数组中是从零开始的…

看看Kevek是怎么回答你的:

: 

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

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

Sort是一个数组。3，英勇是0 ~ 12。所以你不能使用Sort[4]和Valor[13]。
