C# 文件读写

在unity中实现如下：

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

public class FileManager : MonoBehaviour
{
 
    // Start is called before the first frame update
    void Start()
    {
        getSavePath();
    }

    //保存关卡数据
    public void saveLeavelData(string name, string content) {
        string fullPath = getSavePath() + name;
        if (!File.Exists(fullPath)) {
            File.Create(fullPath).Dispose();
        }
        Debug.Log(fullPath);
        if (content != null && content.Length > 0) {
            File.WriteAllText(fullPath, content);
        } 
    }

    //获取关卡数据
    public string getLevelData(string name) {
        string fullPath = getSavePath() + name;
        if (File.Exists(fullPath))
        {
            string content = File.ReadAllText(fullPath);
            return content;
        }
        return null;
    }

    //获取存储路径
    string getSavePath() {
        string savePath = Application.persistentDataPath + "/MathBlock/";
        string path = Path.GetFullPath(savePath);
        if (!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
        return path;
    }

}

注：创建文件后要调Dispose()，不然会报错
