我有這個孤立的存儲幫助器,我需要使用它來保存和檢索我的通用應用程序中的數據。其實,我不知道從哪裏開始。我是否應該製作一個應用程序並將輔助類加入其中? 這裏是我的課,感謝advanvceWindows通用應用程序隔離存儲
using System.IO;
//using System.IO.IsolatedStorage;
using System.Runtime.Serialization.Json;
using System.Text;
public static class IsolatedStorageHelper
{
public static T GetObject<T>(string key)
{
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
if (localSettings.Values.ContainsKey(key))
{
string serializedObject = localSettings.Values[key].ToString();
return Deserialize<T>(serializedObject);
}
return default(T);
}
public static void SaveObject<T>(string key, T objectToSave)
{
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
string serializedObject = Serialize(objectToSave);
localSettings.Values[key] = serializedObject;
}
public static void DeleteObject(string key)
{
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
localSettings.Values.Remove(key);
}
private static string Serialize(object objectToSerialize)
{
using (MemoryStream ms = new MemoryStream())
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(objectToSerialize.GetType());
serializer.WriteObject(ms, objectToSerialize);
ms.Position = 0;
using (StreamReader reader = new StreamReader(ms))
{
return reader.ReadToEnd();
}
}
}
private static T Deserialize<T>(string jsonString)
{
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(jsonString)))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
return (T)serializer.ReadObject(ms);
}
}
}
你可以編輯你的問題,並提供更多的信息,你遇到了什麼問題,你在找什麼? – Romasz
是的,事實上,我需要創建一個應用程序,並在不重寫整個代碼的情況下爲我的實體'person'製作一個crud。因此,我需要使用上面提到的類'storage helper.cs'。現在我被卡住了,因爲我不知道如何使用它,並將其實施到我的項目中。我真的會使用這個類來開發一個UWP的例子。謝謝你的幫助 –
