C# 带有IsolatedStorage设置的FormatException

在序列化

字典

以隔离存储设置时出现问题。我正在做以下工作：

public Dictionary<string, Person> Names = new Dictionary<string, Person>();

if (!IsolatedStorageSettings.ApplicationSettings.Contains("Names"))
        {
            //Add to dictionary
            Names.Add("key", new Person(false,
                new System.Device.Location.GeoCoordinate(0, 0),
                new List<GeoCoordinate>() 
                {
                    new GeoCoordinate(35.8974, 14.5099),
                    new GeoCoordinate(35.8974, 14.5099),
                    new GeoCoordinate(35.8973, 14.5100),
                    new GeoCoordinate(35.8973, 14.5099)
                }));
            //Serialize dictionary to IsolatedStorage
            IsolatedStorageSettings.ApplicationSettings.Add("Names", Names);
            IsolatedStorageSettings.ApplicationSettings.Save();
        }

首先确保您的代码在不保存到IsolatedStorage的情况下无异常运行。然后，您可以尝试只设置值，而不是执行加法

IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
settings["Names"] = Names;
settings.Save();

看起来GeoCoordinate可能无法序列化。您可以尝试为存储创建自己的类，其中包含两个double，然后在检索时将它们转换回来。

可能是这个异常，在这种情况下，您可以安全地忽略它：为了确保，您可以提供完整的调用堆栈吗？因此，我不得不向Person类添加一个XNA矩形，FormatException的数量激增。如此之多以至于我的游戏挂起大约五秒钟直到异常停止。有什么想法吗？我不能让它保持这样。已经尝试过了，代码抛出了一个KeyNotFoundException，因此您最终仍然需要在catch中调用Add（）。您是对的，就是这样。我创建了一个包含两个double的SerializableGeoCoordinate类，并添加了一个助手方法，该方法从标准GeoCoordinate创建SerializableGeoCoordinate。谢谢你的帮助！
