ILSpy反编译C#代码时出现的[MethodImpl(MethodImplOptions.Synchronized)]问题

如下为反编译后的代码

public event EventHandler PageCountChanged
  {
   [MethodImpl(MethodImplOptions.Synchronized)]
   add
   {
    this.PageCountChanged = (EventHandler)Delegate.Combine(this.PageCountChanged, value);
   }
   [MethodImpl(MethodImplOptions.Synchronized)]
   remove
   {
    this.PageCountChanged = (EventHandler)Delegate.Remove(this.PageCountChanged, value);
   }
  }

实际上只是声明了一个事件，只取第一行就好了

public event EventHandler PageCountChanged；
