我正在從IsolatedStorage中讀取數據,但無法在ScheduledTask中對其進行編輯。我如何編輯它?Windows Phone中的IsolatedStorage編輯ScheduledTask
private void StartToastTask(ScheduledTask task)
{
long rank = 0, difference = 0;
string text = "", nickname = "";
PishtiWCF.PishtiWCFServiceClient ws = ServiceClass.GetPishtiWCFSvc();
ws.GetUsersRankCompleted += (src, e) =>
{
try
{
if (e.Error == null)
{
difference = rank - e.Result.GeneralRank;
if (!String.IsNullOrEmpty(nickname))
{
if (difference < 0)
text = string.Format("{0}, {1} kişi seni geçti!", nickname, difference.ToString(), e.Result.GeneralRank);
else if (difference > 0)
text = string.Format("{0}, {1} kişiyi daha geçtin!", nickname, Math.Abs(difference).ToString(), e.Result.GeneralRank);
else if (e.Result.GeneralRank != 1)
text = string.Format("{0}, sıralamadaki yerin değişmedi!", nickname, e.Result.GeneralRank);
else
text = string.Format("{0}, en büyük sensin, böyle devam!", nickname);
}
else
return;
Mutex mut;
if (!Mutex.TryOpenExisting("IsoStorageMutex", out mut))
mut = new Mutex(false, "IsoStorageMutex");
mut.WaitOne();
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = file.OpenFile("UserRanks", FileMode.Open, FileAccess.Write))
{
StreamWriter writer = new StreamWriter(stream);
writer.Write(string.Format("{0},{1}", nickname, e.Result.GeneralRank));
writer.Close();
stream.Close();
}
}
mut.ReleaseMutex();
ShellToast toast = new ShellToast();
toast.Title = "Pishti";
toast.Content = text;
toast.Show();
}
FinishTask(task);
}
catch (Exception)
{
}
};
try
{
Mutex mut;
if (!Mutex.TryOpenExisting("IsoStorageMutex", out mut))
mut = new Mutex(false, "IsoStorageMutex");
mut.WaitOne();
using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication())
{
using (IsolatedStorageFileStream stream = file.OpenFile("UserRanks", FileMode.Open, FileAccess.Read))
{
using (StreamReader reader = new StreamReader(stream))
{
string temp = reader.ReadToEnd();
if (temp.Split(',').Count() > 1)
{
nickname = temp.Split(',')[0];
rank = long.Parse(temp.Split(',')[1]);
ws.GetUsersRankAsync(nickname);
}
reader.Close();
}
stream.Close();
}
}
mut.ReleaseMutex();
}
catch (Exception)
{
}
}
我正在從UserRanks文件級別,例如1200,但是當我和數據從WCF,編輯它以1000並希望將其寫入IsolatedStorage,它不會崩潰的應用程序,但它失敗。
你知道爲什麼嗎?
謝謝。
是你的catch塊空的一個原因?我看到你解決了你的問題,但你表示它不會崩潰但失敗。如果catch塊爲空,則將指示將指示從何處開始故障排除的異常被吞下。一個好的開始就是將catch(Exception)改爲catch(Exception ex),並將一個斷點放在下一行。這樣,即使您計劃忽略異常,但在調試過程中發生異常時,應用程序將停止並允許您檢查它。 – 2014-11-07 00:08:47
