原文 (WinForm)文件夹状态监控,最小化到托盘,开机自启动
1. 文件夾監控（監測文件夾中的文件動態）：
//MSDN上的例子
public class Watcher
{
public static void Main()
{
Run();
}
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
public static void Run()
{
string[] args = System.Environment.GetCommandLineArgs();
// If a directory is not specified, exit program.
if (args.Length != 2)
{
// Display the proper way to call the program.
Console.WriteLine(“Usage: Watcher.exe (directory)“);
return;
}
// Create a new FileSystemWatcher and set its properties.
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = args[1];
/* Watch for changes in LastAccess and LastWrite times, and
the renaming of files or directories. */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch text files.
watcher.Filter = “*.txt“;
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
// Begin watching.
watcher.EnableRaisingEvents = true;
// Wait for the user to quit the program.
Console.WriteLine(“Press \’q\’ to quit the sample.“);
while (Console.Read() != ‘q‘) ;
}
// Define the event handlers.
private static void OnChanged(object source, FileSystemEventArgs e)
{
// Specify what is done when a file is changed, created, or deleted.
Console.WriteLine(“File: “ + e.FullPath + “ “ + e.ChangeType);
}
private static void OnRenamed(object source, RenamedEventArgs e)
{
// Specify what is done when a file is renamed.
Console.WriteLine(“File: {0} renamed to {1}“, e.OldFullPath, e.FullPath);
}
}
2. 最小化到托盤功能：
首先給主界面添加一個notifyIcon控件，給它的Icon添加一個圖標，不添加圖標的話不會在托盤顯示，然後給主界面的SizeChanged事件注冊一個方法，在方法中將主界面隱藏:
void frmMain_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized) {
this.Hide();
}
}
然後給notifyIcon的單擊或者雙擊事件添加一個方法，讓鼠標單擊或者雙擊托盤圖標的時候可以將主界面窗口還原:
private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
}
3.讓程序開機自動啟動的方法（編輯注冊表）
private void chbStartup_CheckedChanged(object sender, EventArgs e)
{
if (this.chbStartup.Checked)
{
try
{
string startupPath = Application.ExecutablePath;
RegistryKey local = Registry.LocalMachine;
RegistryKey run = local.CreateSubKey(@”SOFTWARE\Microsoft\Windows\CurrentVersion\Run“);
run.SetValue(“FolderWatcher“, startupPath);
local.Close();
}
catch (Exception ex)
{
MessageBox.Show(“開機啟動設置異常：“ + ex.Message);
}
}
else {
try
{
string startupPath = Application.ExecutablePath;
RegistryKey local = Registry.LocalMachine;
RegistryKey run = local.CreateSubKey(@”SOFTWARE\Microsoft\Windows\CurrentVersion\Run“);
run.DeleteValue(“FolderWatcher“);
local.Close();
}
catch (Exception ex)
{
MessageBox.Show(“開機啟動設置異常：“ + ex.Message);
}
}
}
