unity学习笔记——读写TXT

先直接贴代码

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

public class ReadTxtManager : MonoBehaviour
{
    private string path = "people";
    public List<People> peopleList = new List<People>();

    void Awake()
    {
        ReadTxt();
        WriteTxt();
        ReadTxt();
    }

    void ReadTxt()
    {
        //1
        TextAsset txt = Resources.Load<TextAsset>(path);//比较简单易懂，适合于只读TXT
        if (txt != null)
        {
			string[] allLine = txt.text.Split('\n');//换行分割每行信息,取到的全部文本在txt.text里
        }


        //2
        FileInfo info = new FileInfo(Application.dataPath + "/Resources/" + path + ".txt");
        if (info.Exists)
        {
            StreamReader reader = info.OpenText();//一般配合写入使用
            string text = reader.ReadToEnd(); //取到的全部文本在reader.ReadToEnd()里，当然也可以使用reader.ReadLine()一行一行取
            Debug.Log(text);
            string[] allLines = text.Split('\n');//换行分割每行信息
            peopleList.Clear();
            for (int i = 1; i < allLines.Length; i++)//从第一行开始，第0行是各列标题
            {
                if (String.IsNullOrEmpty(allLines[i]))
                {
                    continue;//忽略空白行
                }
                string[] line = allLines[i].Split('\t');//制表符分割每项信息
                People peo = new People();
                peo.id = int.Parse(line[0]);
                peo.name = line[1];
                peo.age = int.Parse(line[2]);
                peo.score = int.Parse(line[3]);
                peopleList.Add(peo);//存入列表中
            }
            reader.Dispose();
            reader.Close();//记得在读写后调用关闭，否则会破坏共享
        }
    }

    void WriteTxt()
    {
        FileInfo info = new FileInfo(Application.dataPath + "/Resources/" + path + ".txt");
        StreamWriter writer = null;
        if (info.Exists)
        {
            writer = info.AppendText();
        }
        else
        {
            writer = info.CreateText();//路径不存在则新创建一个TXT
        }
        string line = "5\tddddd\t20\t88";
        writer.WriteLine(line);//写入数据
        writer.Flush();
        writer.Dispose();
        writer.Close();//关闭
    }
}

[Serializable]
public class People
{
    public int id;
    public string name;
    public int age;
    public int score;
}

其中FileInfo StreamWriter 等需要引入System.IO;

TXT表，末尾留一行用来保持格式。

写入后再读取的数据，可以看到已经写入成功了。
