我用它来保存分数每次游戏结束我尝试使用WP7中的独立存储在txt文件中保存很多行,但它只会保存一个,如何保存很多?

IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication(); 
isf.CreateDirectory("Data"); 
StreamWriter sw = new StreamWriter(new IsolatedStorageFileStream("Data\\scoretest.txt", FileMode.Create, isf)); 
sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm") + "         Score: " + punc); 
sw.Close(); 

,并从TXT阅读我用的时候阅读是空

IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication(); 
StreamReader sr = null; 
try 
{ 
    sr = new StreamReader(new IsolatedStorageFileStream(@"Data\scoretest.txt", FileMode.Open, isf)); 
    for (;;) 
    { 
     string x = sr.ReadLine(); 
     if (x == null) 
      break; 
     else 
      listBox1.Items.Add(x); 
    } 
    sr.Close(); 
} 
catch 
{ 
    listBox1.Items.Add(""); 
} 

它只收取最后一个为停止行,为什么它不读取多行?
