【问题标题】：C# Error when saving a list to file将列表保存到文件时出现 C# 错误
【发布时间】：2015-03-29 20:08:14
【问题描述】：

我创建的程序用于记录鼠标和键盘事件。但是当我创建用于保存记录并用于稍后播放的部分时，会出现以下错误。

代码：

public List<MacroEvent> events = new List<MacroEvent>();
Stream stream = File.Open("Macro.bin", FileMode.Create);
BinaryFormatter bin= new BinaryFormatter();
bin.Serialize(stream, events);
stream.Close();

获取错误：

在 mscorlib.dll 中发生了“System.Runtime.Serialization.SerializationException”类型的未处理异常

附加信息：在程序集“System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken = b77a5c561934e089”中键入“System.Windows.Forms.MouseEventArgs”未标记为可序列化。

宏事件

[Serializable]
    public class MacroEvent
    {

        public MacroEventType MacroEventType;
        public EventArgs EventArgs;
        public int TimeSinceLastEvent;

        public MacroEvent(MacroEventType macroEventType, EventArgs eventArgs, int timeSinceLastEvent)
        {
            MacroEventType = macroEventType;
            EventArgs = eventArgs;
            TimeSinceLastEvent = timeSinceLastEvent;
        }
    }

【问题讨论】：

打印出 full 堆栈跟踪 - 那里可能有更多信息。
你能贴出 MacroEvent 类的代码吗？猜测它包含 MouseEvenArgs 类型的成员，如异常所述，它不可序列化。

标签： c#

【解决方案1】：

您不能这样做，因为 MouseEventArgs 不可序列化。您需要创建一个具有与 MouseEventArgs 类似的属性 (X,Y) 的可序列化类，然后将该类序列化为二进制文件。
