我目前正在尝试在本地文件夹上的 C# 上保留创建的新文件的计数器。
我有两个 CD 和 LP 子目录，我必须不断检查。
文件系统观察器仅跟踪我复制的文件夹。 基本上我需要跟踪以 EM* 开头创建的文件夹，但我的代码显示当我复制和粘贴文件夹时计数器增加，而不是当我创建 EM* 文件夹时计数器增加。 例如 EM1 EM2 仅 EM2 复制会增加计数器，即使有时它也会增加 +2
static int LPcounter { get; set; }
static int CDcounter { get; set; }
static int LPCreated;
static int CDCreated;
FileSystemWatcher CDdirWatcher = new FileSystemWatcher();
FileSystemWatcher LPdirWatcher = new FileSystemWatcher();
public Form1()
{
InitializeComponent();
while (true)
watch();
}
public void watch()
{
CDdirWatcher.Path = @"C:\Data\LotData\CD";
CDdirWatcher.Filter = "EM*";
CDdirWatcher.NotifyFilter = NotifyFilters.DirectoryName | NotifyFilters.LastWrite;
CDdirWatcher.EnableRaisingEvents = true;
CDdirWatcher.Created += CDdirWatcher_Created;
LPdirWatcher.Path = @"C:\Data\LotData\LP";
LPdirWatcher.Filter = "EM*";
LPdirWatcher.NotifyFilter = NotifyFilters.DirectoryName;
LPdirWatcher.EnableRaisingEvents = true;
LPdirWatcher.Created += LPdirWatcher_Created;
}
private static void CDdirWatcher_Created(object sender, FileSystemEventArgs e)
{
CDCreated += 1;
}
private static void LPdirWatcher_Created(object sender, FileSystemEventArgs e)
{
LPCreated += 1;
}
最佳答案
您的代码是正确的，尝试使用控制台和 MKDIR 创建目录，它会起作用。如果您从资源管理器创建目录，则首先将其创建为“新文件夹”，然后重命名。
来自 Microsoft 网站:复制和粘贴被解释为重命名 https://learn.microsoft.com/en-us/dotnet/api/system.io.filesystemwatcher.notifyfilter?view=netframework-4.8
The operating system and FileSystemWatcher object interpret a cut-and-paste action or a move action as a rename action for a folder and its contents
在同一个文档中，事件可以多次引发:
Common file system operations might raise more than one event. For example, when a file is moved from one directory to another, several OnChanged and some OnCreated and OnDeleted events might be raised.
