Unity3D之文件讀寫

最近想用txt來做安卓遊戲的地圖配置，寫了很久都不對。。於是乎。。。

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

public class CanSeleteGame : MonoBehaviour
{
    
    public GameObject lable;

    private string strTxt;

    void Awake()
    {
    }
    string path = "";
    // Use this for initialization
    void Start()
    {

        if (Application.platform == RuntimePlatform.Android)
        {
            path = Application.persistentDataPath;
        }
        else if (Application.platform == RuntimePlatform.WindowsPlayer)
        {
            path = Application.dataPath;
        }
        else if (Application.platform == RuntimePlatform.WindowsEditor)
        {
            path = Application.dataPath;
        }

        strTxt = LoadFile(path, "t.txt");
        if (strTxt != "error")
        {
            lable.GetComponent<UILabel>().text = "read:" + strTxt;
        }
        else
        {
            createORwriteConfigFile(path, "t.txt", "111000000000000000000000000000000000000000000000000000000000");
            string str = LoadFile(path, "t.txt");
            lable.GetComponent<UILabel>().text = "create:" + str;
        }
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            //WriteIn("100");
            string str = LoadFile(path, "t.txt");
            lable.GetComponent<UILabel>().text = "REad:" + str;
        }
    }

        if (!t.Exists)
        {
            return "error";
        }
        StreamReader sr = null;
        sr = File.OpenText(path + "//" + name);
        string line;
        while ((line = sr.ReadLine()) != null)
        {
            break;
        }
        sr.Close();
        sr.Dispose();
        return line;
    }
}

注意：各個平臺的文件存放位置不同。

2.. Application.persistentDataPath;這個路徑只能在程序運行時纔可以做操作，也就是說，在程序沒有運行時，將文件放在這個路徑中是無效的（好坑爹 = =）
