C# 設置程式啟動項

托盤圖標設置

新建一個NotifyIcon，會在托盤處顯示一個圖標。

NotifyIcon.Icon可以直接設置一個ico圖片，也可以延用原有程式的圖標。

notifyIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(Application.ExecutablePath);

 1     public partial class MainWindow : Window

禁用多進程啟動

1     //禁止雙進程
2     bool canCreateNew;
3     using (System.Threading.Mutex m = new System.Threading.Mutex(true, System.Windows.Forms.Application.ProductName, out canCreateNew))

6         {
7             this.Shutdown();
8         }
9     }

刪除原有進程

 1     /// <summary>
 2     /// 刪除原有進程
 3     /// </summary>
 4     /// <param name="processName"></param>
 5     private void KillProcess(string processName)
 6     {
 7         //得到所有打開的進程   
 8         try
 9         {
10             Process currentProcess = Process.GetCurrentProcess();
11             var processes = Process.GetProcessesByName(processName).Where(process=> process.Id!=currentProcess.Id);
12             foreach (Process thisproc in processes)
13             {
14                 //找到程式進程,kill之。
15                 if (!thisproc.CloseMainWindow())
16                 {
17                     thisproc.Kill();
18                 }
19             }
20         }
21         catch (Exception ex)
22         {
23                 
24         }

設置開機自啟動

 1     private void SetAppAutoRun(bool autoRun)
 2     {
 3         if (autoRun) //設置開機自啟動  
 4         {

 7             RegistryKey rk = Registry.LocalMachine;
 8             RegistryKey rk2 = rk.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");
 9             rk2.SetValue("JcShutdown", path);
10             rk2.Close();
11             rk.Close();
12         }
13         else //取消開機自啟動  
14         {
16             RegistryKey rk = Registry.LocalMachine;
17             RegistryKey rk2 = rk.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");
18             rk2.DeleteValue("JcShutdown", false);
19             rk2.Close();
20             rk.Close();
21         }
22     }
