Question

我正在尝试跟踪文件系统的变化。因此我使用FileSystemWatcher。遗憾的是，Renamed事件不提供Windows 7和Windows 8上的oldName信息。在Windows XP上，它完美无缺。

这是我的计划：

using System;
using System.IO;

namespace Watcher2
{

class Program
{
    static void Main(string[] args)
    {

        Console.WriteLine("Enter Folder Name:");
        string folder = Console.ReadLine();
        Console.WriteLine("Watching folder "+folder);

        FileSystemWatcher watcher = new FileSystemWatcher(folder, "*.*");
        watcher.EnableRaisingEvents = true;
        watcher.IncludeSubdirectories = true;

        watcher.Renamed += watcher_Renamed;

        Console.ReadLine();

    }

    static void watcher_Renamed(object sender, RenamedEventArgs e)
    {
        Console.WriteLine(string.Format("OldName is {0} \nName is {1}\nOldFullPath is {2}\nFullPath is {3}", (e.OldName ?? "NULL"), e.Name, e.OldFullPath, e.FullPath));
    }
}

RenamedEventArgs不提供OldName（e.OldName为NULL）。使用Windows XP是没有选择:)

我在这里错过了什么吗？

Answer 1

我现在更新到Windows 8.1，我按预期获得OldName ..

重命名文件oldName时，.Net FileSystemWatcher为null
