fileReader = new StreamReader(new IsolatedStorageFileStream("textfiles\\easy.txt", FileMode.Open, filestorage));
var obj = App.Current as App;
var lines = fileReader.ReadToEnd();
obj.textfile = (string[])fileReader.ReadToEnd();
收到错误
obj.textfile = (string[])fileReader.ReadToEnd() 中的“无法将字符串转换为字符串 []”;
