Question

因此，当我最初写这篇文章大约6个月前它工作正常，但现在由于某种原因它捕获。我对编码很新，不知道如何缩小编码以找出如何解决这个问题。任何建议将不胜感激。（它基于一个教程，很少从该教程中更改。添加了一些子节点以保存XML。）如果我在＆＃34; playerdata.LoadXml ...＆＃34;之后在每一行上设置断点在第一个＆＃34; foreach＆＃34;之前它会跳过maxhp，maxcarry，trouble和player.CurrentLocation。

public static Player CreatePlayerFromXmlString(string xmlPlayerData)
    {
        try
        {
            XmlDocument playerData = new XmlDocument();
            playerData.LoadXml(xmlPlayerData);
            int currenthp = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/CurrentHP").InnerText);
            int maxhp = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/MaxHP").InnerText);
            int gold = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/Gold").InnerText);
            int xp = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/XP").InnerText);
            int lvl = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/Lvl").InnerText);
            decimal currentcarry = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/CurrentCarry").InnerText);
            decimal maxcarry = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/MaxCarry").InnerText);
            int trouble = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/Trouble").InnerText);
            Player player = new Player(currenthp, maxhp, gold, xp, lvl, currentcarry, maxcarry, trouble);
            int currentLocationID = Convert.ToInt32(playerData.SelectSingleNode("/Player/Stats/CurrentLocation").InnerText);
            player.CurrentLocation = World.LocationByID(currentLocationID);
            foreach (XmlNode node in playerData.SelectNodes("/Player/InventoryItems/InventoryItem"))
            {
                int id = Convert.ToInt32(node.Attributes["ID"].Value);
                int quantity = Convert.ToInt32(node.Attributes["Quantity"].Value);
                for (int i = 0; i < quantity; i++)
                {
                    player.AddItemToInventory(World.ItemByID(id));
                }
            }
            foreach (XmlNode node in playerData.SelectNodes("/Player/PlayerQuests/PlayerQuest"))
            {
                int id = Convert.ToInt32(node.Attributes["ID"].Value);
                bool isCompleted = Convert.ToBoolean(node.Attributes["IsComplete"].Value);
                PlayerQuest playerQuest = new PlayerQuest(World.QuestByID(id));
                playerQuest.IsComplete = isCompleted;
                player.Quests.Add(playerQuest);
            }
            return player;
        }
        catch
        {
            return Player.CreateDefaultPlayer();
        }
    }

Answer 1

catch (Exception e)
{
   Console.WriteLine("{0} Exception caught.", e);
   Console.WriteLine(e.StackTrace);
}

这应该会让你更多地了解正在发生的事情。

Answer 2

当您调用try / catch时，您可以通过指定要捕获的异常来指定要捕获的内容：

try
{
    // do stuff...
}
catch ( Exception e1 )
{
    // do stuff with e1...
    Console.WriteLine(e1.Number + " - " + e1.Message);
}
catch ( AnotherException e2 )
{
    // do stuff with e2...
    Console.WriteLine(e2.Number + " - " + e2.Message);
}
etc...
