如何将数组列表存储到独立存储中?也可以将图像放置在数组列表中吗?谢谢
就像评论所说的那样,您所需要的只是获取一些可序列化的对象,并且能够将其存储在IS中。请注意,多个维度的数组不可序列化!
这是我用于IS的代码块:
using System.IO;
using System.IO.IsolatedStorage;
using System.Xml.Serialization;
namespace PhoneApp1
{
public class IsolatedStorage
{
public static void SaveToIs(String fileName, Object saved)
{
try
{
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
{
if (isf.FileExists(fileName))
{
isf.DeleteFile(fileName);
}
using (IsolatedStorageFileStream fs = isf.CreateFile(fileName))
{
XmlSerializer ser = new XmlSerializer(saved.GetType());
ser.Serialize(fs, saved);
}
}
}
catch (IsolatedStorageException ex)
{
MessageBox.Show(ex.Message);
}
}
public static Object loadFromIS(String fileName, Type t)
{
Object result = null;
try
{
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
{
if (isf.FileExists(fileName))
{
using (StreamReader sr = new StreamReader(isf.OpenFile(fileName, FileMode.Open)))
{
XmlSerializer ser = new XmlSerializer(t);
result = ser.Deserialize(sr);
}
}
}
}
catch (IsolatedStorageException ex)
{
MessageBox.Show(ex.Message);
}
catch (InvalidOperationException e)
{
MessageBox.Show(e.Message);
}
return result;
}
}
}
