好，我设法弄清楚了:)这是我所做的:

Ok I've managed to figure it out :) Here's what I did:

INSTRUMENT_DATA_SHEET _original = (INSTRUMENT_DATA_SHEET)e.OriginalObject;
INSTRUMENT_DATA_SHEET_HISTORY _history = new INSTRUMENT_DATA_SHEET_HISTORY();

foreach (PropertyInfo pi in _original.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
{
    _history.GetType().GetProperty(pi.Name).SetValue(_history, pi.GetValue(_original, null), null);
}

不是很优雅，但是可以完成工作！

Not very elegant but it gets the job done!
