Unity在Android端PC端以及编辑器环境下读取并写入文本的操作，直接上代码
创建并写入文本内容
//创建并写入fileName为文件名称(记得加后缀)content为需要写入的文本内容public void CreateFileInPersistentData(string fileName,string content){string path = Application.persistentDataPath + "/" + fileName;if (File.Exists(path)){return;}else{FileStream fs = new FileStream(path, FileMode.Create); fs.Close();WriteTXT(fileName, content); }}
写入文本内容
public void WriteTXT(string fileName, string s){string url = "";if (Application.platform == RuntimePlatform.Android){url = Application.persistentDataPath + "/" + fileName;File.WriteAllText(url, s);}else if (Application.platform == RuntimePlatform.WindowsEditor || Application.platform == RuntimePlatform.WindowsPlayer){url = Application.persistentDataPath + "/" + fileName;FileStream fs = new FileStream(url, FileMode.Open);byte[] bytes = new UTF8Encoding().GetBytes(s.ToString());fs.Write(bytes, 0, bytes.Length);fs.Close();}}
读取文本内容
public string LoadTXTtoString(string fileName){string url = Application.persistentDataPath + "/" + fileName;string s = "";if (Application.platform == RuntimePlatform.Android){s = File.ReadAllText(url);}else if (Application.platform == RuntimePlatform.WindowsEditor || Application.platform == RuntimePlatform.WindowsPlayer){FileStream fs = new FileStream(url, FileMode.Open);byte[] bytes = new byte[100];fs.Read(bytes, 0, bytes.Length);//将读取到的二进制转换成字符串s = new UTF8Encoding().GetString(bytes);fs.Close();}return s;}
调用方法演示
public Text show_text;public Button ok_btn;private void Awake(){CreateFileInPersistentData("test.txt", "这是一个测试文本..."); }private void Start(){ok_btn.onClick.AddListener(() => {show_text.text = LoadTXTtoString("test.txt"});}
