不久前我遇到了this，我认为它可以满足您的需求。这是那里的副本，以防它消失。
当我编写我的第一个 Word AfterSave Event 条目时，它是为 Word 2007 设计的，而且 - 事实证明 - 并不是一个包罗万象的东西。所以我在这里更新了它（感谢 Pat Lemm 的收获）。
关闭文档后，您永远无法访问已保存的文件名。所以，我在这里更新了代码，它现在可以在所有条件下工作，并且已经在 Word 2013 中进行了测试。
这是它的工作原理：
- 初始化时，您将 Word 对象传递给它。
- 它附加到保存前事件。
- 当任何保存事件发生时，它会启动一个循环直到后台保存完成的线程。
-
后台保存完成后，它会检查文档 Saved == true：
- 如果 Saved == true：则确实发生了常规保存。
- 如果 Saved == false：那么它必须是 AutoSave
在每种情况下，它都会触发一个独特的事件：
- AfterSaveUiEvent
- AfterSaveEvent
- AfterAutoSaveEvent
此外，如果正在保存的文档也正在关闭，我们会在退出时捕获 WindowDeactivate 事件中的文件名。调用者现在可以访问它（如下例所示），以获取已关闭文档的完整文件名。
这是类的代码：
public class WordSaveHandler
{
public delegate void AfterSaveDelegate(Word.Document doc, bool isClosed);
// public events
public event AfterSaveDelegate AfterUiSaveEvent;
public event AfterSaveDelegate AfterAutoSaveEvent;
public event AfterSaveDelegate AfterSaveEvent;
// module level
private bool preserveBackgroundSave;
private Word.Application oWord;
string closedFilename = string.Empty;
/// <summary>
/// CONSTRUCTOR takes the Word application object to link to.
/// </summary>
/// <param name="oApp"></param>
public WordSaveHandler(Word.Application oApp)
{
oWord = oApp;
// hook to before save
oWord.DocumentBeforeSave += oWord_DocumentBeforeSave;
oWord.WindowDeactivate += oWord_WindowDeactivate;
}
/// <summary>
/// Public property to get the name of the file
/// that was closed and saved
/// </summary>
public string ClosedFilename

{
return closedFilename;
}
}

{
// This could mean one of four things:
// 1) we have the user clicking the save button
// 2) Another add-in or process firing a resular Document.Save()
// 3) A Save As from the user so the dialog came up
// 4) Or an Auto-Save event
// so, we will start off by first:
// 1) Grabbing the current background save flag. We want to force
// the save into the background so that Word will behave
// asyncronously. Typically, this feature is on by default,
// but we do not want to make any assumptions or this code
// will fail.

// BackgroundSaveStatus of Word. And when that flag is OFF
// no know we are AFTER the save event
preserveBackgroundSave = oWord.Options.BackgroundSave;
oWord.Options.BackgroundSave = true;
// kick off a thread and pass in the document object
bool UiSave = SaveAsUI; // have to do this because the bool from Word
// is passed to us as ByRef
new Thread(() =>
{
Handle_WaitForAfterSave(Doc, UiSave);
}).Start();
}
/// <summary>

这是你如何设置它并附加到它的事件：
public partial class ThisAddIn
{
WordSaveHandler wsh = null;
private void ThisAddIn_Startup(object sender,
System.EventArgs e)
{
// attach the save handler
wsh = new WordSaveHandler(Application);
wsh.AfterAutoSaveEvent += new WordSaveHandler.AfterSaveDelegate(wsh_AfterAutoSaveEvent);
wsh.AfterSaveEvent += new WordSaveHandler.AfterSaveDelegate(wsh_AfterSaveEvent);
wsh.AfterUiSaveEvent += new WordSaveHandler.AfterSaveDelegate(wsh_AfterUiSaveEvent);
}
void wsh_AfterUiSaveEvent(Word.Document doc, bool isClosed)
{
if (!isClosed)
MessageBox.Show("After SaveAs Event");
else
MessageBox.Show("After Close and SaveAs Event. The filname was: " + wsh.ClosedFilename);
}
void wsh_AfterSaveEvent(Word.Document doc, bool isClosed)
{
if (!isClosed)
MessageBox.Show("After Save Event");
else
MessageBox.Show("After Close and Save Event. The filname was: " + wsh.ClosedFilename);
}
void wsh_AfterAutoSaveEvent(Word.Document doc, bool isClosed)
{
MessageBox.Show("After AutoSave Event");
}
// etc.
}
