创建本地文件，需要使用FileInfo类，在构造方法中写入文件的保存路径，通过FileInfo的对象使用CreateText方法，可在本地创建一个文本文件

使用AppendText方法打开已经创建的文本，最后WriteLine可以将字符串写入文本

StreamReader sr =File.OpenText(path + "//" + name);

打开文本，sr.ReadLine()进行读取

void Start () {

CreateFile (Application.dataPath,"FileName","TestInfo0");

CreateFile (Application.dataPath,"FileName","TestInfo1");

CreateFile (Application.dataPath,"FileName","TestInfo2");

ArrayList arrlist = LoadFile(Application.dataPath,"FileName");

foreach (string str in arrlist) {

Debug.Log("--------------------" + str);

}

}

/**将文本写入文件*/

void CreateFile(string path,string name,string info)

{

StreamWriter sw;

FileInfo t = new FileInfo (path + "//" + name);

if (!t.Exists)

{

sw = t.CreateText ();

} else

{

sw = t.AppendText();

}

sw.WriteLine (info);

sw.Close ();

sw.Dispose ();

}

/**文件的读取*/

ArrayList LoadFile(string path,string name)

{

StreamReader sr = null;

try{

sr = File.OpenText(path + "//" + name);

}

catch(Exception e)

{

Debug.Log("没有文件" + e.Message);

return null;

}

string line;

ArrayList arrList = new ArrayList ();

while ((line = sr.ReadLine()) != null) {

arrList.Add(line);

}

sr.Close ();

sr.Dispose ();

return arrList;

}
