【问题描述】：
所以我一直在为学校作业构建一个应用程序，它是一个适合我学校筹款日的投注应用程序。它允许您对当天某些事件的结果进行投注，例如哪支球队将赢得泡泡足球，或者谁将赢得师生辩论，等等。我需要在某个地方存储许多事件及其结果，事件和结果是单独的对象。有人告诉我最好的存储方式是二进制。为此，我被告知要创建另一个应用程序，这将允许我创建、编辑和删除这些对象，然后将它们序列化为二进制文件，以便稍后由应用程序反序列化。序列化为二进制工作。应用程序方面的反序列化，并没有那么多。
这是序列化器：
namespace MazBrokes_Editor
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
private List<Event> mEvents;
private List<string> mEventNames = new List<string>();
private Dictionary<Event, Outcome> mOutcomesToRemove = null;
private List<string> mOutcomeNames;
private static string file;
private Event SelectedEvent = null;
private Outcome SelectedOutcome = null;
public MainWindow()
{
InitializeComponent();
}
private void btnEventAdd_Click(object sender, RoutedEventArgs e)
{
mEvents.Add(new Event(
txtEventName.Text,
txtEventType.Text,
txtEventDesc.Text,
new List<Outcome>()
));
}
private void btnAddOutcome_Click(object sender, RoutedEventArgs e)
{
if (txtEventOrigin.Text == "")
{
SelectedEvent.Outcomes.Add(new Outcome(txtName.Text, txtProbability.Text, txtPrizeDesc.Text, txtBetMultiplier.Text));
}
foreach (var item in mEvents)
{
if (item.eventName != txtEventOrigin.Text)
{
continue;
}
else
{
item.Outcomes.Add(new Outcome(txtName.Text, txtProbability.Text, txtPrizeDesc.Text, txtBetMultiplier.Text));
}
}
Clear();
}
private void btnSerialize_Click(object sender, RoutedEventArgs e)
{
using (Stream stream = File.Open(file, FileMode.Create))
{
var binaryformatter = new BinaryFormatter();
binaryformatter.Serialize(stream, mEvents);
}
}
private void btnDeserialize_Click(object sender, RoutedEventArgs e)
{
FileStream fs = File.Open(file, FileMode.Open);
BinaryFormatter formatter = new BinaryFormatter();
mEvents = formatter.Deserialize(fs) as List<Event>;
foreach(var item in mEvents)
{
mEventNames.Add(item.eventName);
}
fs.Flush();
fs.Close();
fs.Dispose();
lstDesirializedObjects.ItemsSource = mEventNames;
}
private void lstDesirializedObjects_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
mOutcomeNames = new List<string>();
foreach (var item in mEvents)
{
if (lstDesirializedObjects.SelectedItem.ToString() != item.eventName)
{
continue;
}
else
{
txtEventName.Text = item.eventName;
txtEventDesc.Text = item.Description;
txtEventType.Text = item.eventType;
SelectedEvent = item;
foreach(var outcome in SelectedEvent.Outcomes)
{
mOutcomeNames.Add(outcome.Name);
}
lstDesirializedOutcomes.ItemsSource = mOutcomeNames;
}
}
}
private void BtnEventEdit_Click(object sender, RoutedEventArgs e)
{
SelectedEvent.eventName = txtEventName.Text;
SelectedEvent.Description = txtEventDesc.Text;
SelectedEvent.eventType = txtEventType.Text;
}
private void lstDesirializedOutcomes_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
foreach (var item in SelectedEvent.Outcomes)
{
if (lstDesirializedOutcomes.SelectedItem.ToString() != item.Name)
{
continue;
}
else
{
txtName.Text = item.Name;
txtProbability.Text = item.oddsArray[0] + "/" + item.oddsArray[1];
txtPrizeDesc.Text = item.Prize;
txtBetMultiplier.Text = Convert.ToString(item.mPayout);
SelectedOutcome = item;
}
}
}
private void btnEditOutcome_Click(object sender, RoutedEventArgs e)
{
SelectedOutcome.Name = txtName.Text;
SelectedOutcome.oddsArray = txtProbability.Text.Split('/');
SelectedOutcome.Prize = txtPrizeDesc.Text;
SelectedOutcome.mPayout = Convert.ToDouble(txtBetMultiplier.Text);
Clear();
}
private void btnDeleteOutcome_Click(object sender, RoutedEventArgs e)
{
mOutcomesToRemove = new Dictionary<Event, Outcome>();
foreach (var Event in mEvents)
{
foreach (var outcome in Event.Outcomes)
{
if (SelectedOutcome != outcome)
{
continue;
}
else
{
//Event.Outcomes.Remove(outcome);
mOutcomesToRemove.Add(Event, outcome);
}
}
}
foreach (var item in mOutcomesToRemove)
{
item.Key.Outcomes.Remove(item.Value);
}
}
private void DeleteOutcome(Event evvent, Outcome outcome)
{
evvent.Outcomes.Remove(outcome);
}
private void btnDeleteevent_Click(object sender, RoutedEventArgs e)
{
mEvents.Remove(SelectedEvent);
}
public void Clear()
{
txtEventOrigin.Text = "";
txtName.Text = "";
txtProbability.Text = "";
txtPrizeDesc.Text = "";
txtBetMultiplier.Text = "";
}
}
}`
反序列化器：
namespace MazBrokes
{
class configParser
{
public static void SerializeParse()
{
BinaryFormatter formatter = new BinaryFormatter();
SlidingTabFragment.UpcomingEvents.mEvents = formatter.Deserialize(MainActivity.assets.Open("MazBrokesData.bin")) as List<Events>;
}
}
}
我被抛出了这里详述的异常： BinaryFormatter deserialize gives SerializationException.
我尝试了推荐的修复方法，但这只会导致更多错误。
非常感谢您提供的任何帮助，如果我可以提供更多信息，请说。
【问题讨论】：
-
您是否有不能使用 JSON 进行数据传输的原因？处理起来容易得多
-
我会调查的，谢谢，杰森。
