Question

我正在编写一个Unity脚本，该脚本读取CSV文件（2D和所有数字），并将其分解为附加到2D浮点数组的浮点数。这是我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class LoadCalibration : MonoBehaviour
{
    public float[,] pc_array; // Reconstructed PC coefficient MD array (PCs as rows and variables as columns)

    // Start is called before the first frame update
    void Start()
    {
        // PC COEFFICIENTS

        pc_array = new float[20, 20];
        Debug.Log(pc_array);

        TextAsset pc_data = Resources.Load<TextAsset>("pc_coeff"); //Data is in as variables x PCs

        string[] variable = pc_data.text.Split(new char[] { '\n' }); // split pc_data into rows(each row is one variable, for all PCs)

        for (int i = 0; i < variable.Length - 1; i++)
        {
            string[] pc = variable[i].Split(new char[] { ',' }); // delegate each variable to a pc
            Debug.Log(i);

            for (int j = 0; j < pc.Length; i++)
            {
                Debug.Log(j);
                pc_array[j,i] = float.Parse(pc[j]); // Load float value into the pc_coeff MD array
            }

        }

    }
}

它引发了我这个错误：

IndexOutOfRangeException: Index was outside the bounds of the array.
LoadCalibration.Start () (at Assets/Scripts/LoadCalibration.cs:31)

使用Debug.Log()，我算出该错误发生在i = 0和j = 0（数组的第一个索引）处，即使我将其声明为20 x 20数组也是如此。我是C＃的新手，所以错误很明显，但我无法解决。任何帮助将非常感激！

我已经使用Debug.Log()来评估其余代码是否正常工作（也就是读取CSV文件并将每个字符串条目转换为单个浮点数）。

Answer 1

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

更改为

  for (int j = 0; j < pc.Length; j++)

数组的第一个索引返回IndexOutOfRangeException
