如何刪除我的電腦中的自動運行

Question

我創建了一個名爲（WindowStartup.EXE）的示例應用程序，顯示計算機名稱，操作系統版本和用戶登錄。此應用程序還包含啓動機器時的自動運行行爲。請參閱下面的代碼。代碼寫在C＃

private void InfoWindow_Load(object sender, EventArgs e) 
{ 
    lblMachineName.Text = Environment.MachineName.ToString(); 
    lblOSVersion.Text = Environment.OSVersion.ToString(); 
    lblUserlogged.Text = Environment.UserName.ToString(); 
    this.Top = Screen.PrimaryScreen.WorkingArea.Bottom - this.Height; 
    this.Left = Screen.PrimaryScreen.WorkingArea.Right - this.Width; 

    if (StartUp()) StartUpSystem(); 
} 

private bool StartUp() 
{ 
    bool retVal = false; 
    if (File.Exists(Application.StartupPath + "\\SystemFile.txt")) 
    { 
     //read text file if content is true 
     Stream file = new FileStream(Application.StartupPath + "\\SystemFile.txt", FileMode.Open, FileAccess.Read); 
     StreamReader reader = new StreamReader(file); 
     string content = reader.ReadToEnd(); 
     if (content == "true") retVal = true; 
    } 
    return retVal; 
} 

private void StartUpSystem() 
{ 
    RegistryKey regApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true); 
    if (IsStartupItem()) 
    { 
     //--> Add the value in the registry so that the application runs at startup 
     regApp.SetValue("WindowStartup.EXE", Application.ExecutablePath.ToString()); 

    } 
} 

private bool IsStartupItem() 
{ 
    // The path to the key where Windows looks for startup applications 
    RegistryKey regApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true); 

    if (regApp.GetValue("WindowStartup.EXE") == null) 
     // The value doesn't exist, the application is not set to run at startup 
     return false; 
    else 
     // The value exists, the application is set to run at startup 
     return true; 
} 

在創建安裝程序並將其安裝到我的機器中後，它運行時沒有錯誤。但是在卸載這個示例應用程序時，每次啓動我的機器時它都會彈出。

我會嘗試下面的代碼，請從註冊表中的值，但似乎它不工作

private void StartUpSystem() 
{ 
    RegistryKey regApp = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true); 
    if (!IsStartupItem()) 
    { 
     //--> Remove the value from the registry so that the application doesn't start 
     regApp.DeleteValue("WindowStartup.EXE", false); 

    } 
} 

誰能幫我上我如何通過編程將其刪除？

Answer 1

private void DeleteRegistryKey() 
    { 
     using (RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run", true)) 
     { 
      if (null != key && IsStartupItem()) 
      { 
       key.DeleteValue("MyApp"); 
      } 
     } 
    } 

    private bool IsStartupItem() 
    { 
     // The path to the key where Windows looks for startup applications 
     RegistryKey regApp = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run", true); 

     if (regApp.GetValue("MyApp") == null) 
      // The value doesn't exist, the application is not set to run at startup 
      return false; 
     else 
      // The value exists, the application is set to run at startup 
      return true; 
    } 

    private static void SetRegistry(string path) 
    { 
     if (!IsStartupItem()) 
     { 
      Registry.SetValue(@"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run", "MyApp", path); 
     } 
    } 

Answer 2

那不是：

if(IsStartupItem()) //rather than !IsStartupItem() ?
