调试WP7崩溃
本文关键字：崩溃 WP7 调试 | 更新日期: 2023-09-27 18:05:11
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弹出的。我需要一些帮助来破译这个。
这是堆栈轨道:

所以我可以看到它卡在button4_Click功能和添加Iso存储设置，但这里还发生了什么?我不明白是什么导致一些人崩溃。
这是问题中的代码:
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。
查看IsolatedStorageSettings.Add()的文档:
ArgumentException key already exists in the dictionary.
用IsolatedStorageSettings["FirstPush"] = "true"代替。如果键已经存在，它将创建或更新键，而不会抛出异常。
