我第一次尝试 WP7 的堆栈跟踪。
这给我带来了特别的麻烦，并且是从我的应用程序的几个用户中弹出的。我需要一些帮助来破译这个问题。
这是堆栈轨迹:

所以我可以看到它卡在了button4_Click 函数上并添加了Iso 存储设置，但是这里还发生了什么？我无法理解是什么导致了某些人崩溃。
这是有问题的代码:
private void button4_Click(object sender, RoutedEventArgs e)
{
var settings = IsolatedStorageSettings.ApplicationSettings;
settings.Add("FirstPush", "true");
var hide = Visibility.Collapsed;
grid4.Visibility = hide;
SE_service_btn_Click1();
}
谢谢。任何指导表示赞赏。
最佳答案
看看documentation对于IsolatedStorageSettings.Add():
ArgumentException key already exists in the dictionary.
改用IsolatedStorageSettings["FirstPush"] = "true"。如果 key 已经存在，这将创建或更新 key ，而不会引发异常。
