FileSystemWatcher不觸發Office文件更改中的事件

Question

我正在嘗試使用FileSystemWatcher來鏡像兩個目錄，但是我遇到了Office文件的障礙。 當文檔/電子表格等發生更改時，我似乎無法獲得事件。 這並不是說我沒有收到任何事件，因為我了解Office應用程序經常使用臨時文件。

這是使用以下代碼的示例示例：

// Create the new watcher and hook up events
FileSystemWatcher fsw = new FileSystemWatcher(source);
fsw.NotifyFilter = NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Attributes | NotifyFilters.Size | NotifyFilters.LastWrite | NotifyFilters.LastAccess | NotifyFilters.CreationTime | NotifyFilters.Security;
fsw.IncludeSubdirectories = true;
fsw.InternalBufferSize = 64000;
fsw.Renamed += Fsw_Renamed;
fsw.Error += Fsw_Error;
fsw.Deleted += (o, e) => OnChange(pair, e);
fsw.Changed += (o, e) => OnChange(pair, e);
fsw.Created += (o, e) => OnChange(pair, e);
fsw.EnableRaisingEvents = true;

我看到的事件如下（在onChange ， Fsw_Error和Fsw_Renamed使用斷點）：

我創建word文檔

1. Created 新的Microsoft Word Document.docx
2. Changed 新的Microsoft Word Document.docx

我打開word文檔

3. Created 〜$ w Microsoft Word Document.docx
4. Changed 〜$ w Microsoft Word Document.docx
5. Changed 〜$ w Microsoft Word Document.docx

我編輯然后保存Word文檔

6. Created 〜WRD0000.tmp

我進行更多編輯，然后保存Word文檔

沒有活動...

我真的不太明白這是如何工作的。 原始docx文件正在更新，但是沒有看到任何重命名事件或修改。 我在這里想念什么嗎？

這里的文檔指示需要設置Filter屬性

甚至文檔下面的示例似乎也明確設置了Filter屬性

從那里引用

要監視所有文件中的更改，請將Filter屬性設置為空字符串（“”）或使用通配符（“ 。 ”）。 要觀看特定文件，請將Filter屬性設置為文件名。 例如，要監視文件MyDoc.txt中的更改，請將Filter屬性設置為“ MyDoc.txt”。 您還可以監視某種文件類型的更改。 例如，要監視文本文件中的更改，請將Filter屬性設置為“ * .txt”。

您可以嘗試將其設置為*.docx

更新資料

從下面的評論，上面的清除顯然沒有用。

我這樣寫了一個簡單的控制台程序

class Program
{
    static void Main(string[] args)
    {
        var source = "D:\\temp\\folder";

        // Create the new watcher and hook up events
        var fsw = new FileSystemWatcher(source)
        {
            NotifyFilter = NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Attributes | NotifyFilters.Size | NotifyFilters.LastWrite | NotifyFilters.LastAccess | NotifyFilters.CreationTime | NotifyFilters.Security,
            IncludeSubdirectories = true,
            InternalBufferSize = 64000
        };

        using (fsw)
        {
            fsw.Renamed += (o, e) => Console.WriteLine($"{e.OldFullPath} renamed to {e.FullPath}");
            fsw.Error += (o, e) => Console.WriteLine($"{e}");
            fsw.Deleted += (o, e) => Console.WriteLine($"{e.FullPath} deleted");
            fsw.Changed += (o, e) => Console.WriteLine($"{e.FullPath} changed");
            fsw.Created += (o, e) => Console.WriteLine($"{e.FullPath} created");
            fsw.EnableRaisingEvents = true;

            Console.WriteLine("Ready. Press 'Q' to exit");
            while (Console.ReadKey().KeyChar != 'Q')
            {
            }
        }
    }
}

產生以下輸出

啟動時

Ready. Press 'Q' to exit

如果您運行此示例代碼並看到與我相似的（和預期的）輸出，則可以修改代碼以使用此代碼。
