+ | ====== 2025-04-19 C# 如何獲取與設定Windows suspend, shutdown, sleep, 等狀態設定與展示如何進入 ====== | ||
+ | * 在 C# 中,可以使用 `System.Management` 命名空間来查詢和設定 Windows 系統狀態,比如獲取和設定電源管理介面。這裡是如何獲取和設定與 Windows suspend、shutdown、sleep 等相關狀態的示例: | ||
+ | ===== 獲取電源狀態 ===== | ||
+ | * 要獲取Windows的電源狀態,你可以使用 WMI(Windows Management Instrumentation)。以下是示例代碼段: | ||
+ | * <sxh c#>using System; | ||
+ | using System.Management; | ||
+ | |||
+ | class Program | ||
+ | { | ||
+ | static void Main() | ||
+ | { | ||
+ | GetPowerStatus(); | ||
+ | } | ||
+ | |||
+ | static void GetPowerStatus() | ||
+ | { | ||
+ | ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PowerSetting"); | ||
+ | foreach (ManagementObject powerSetting in searcher.Get()) | ||
+ | { | ||
+ | Console.WriteLine($"Name: {powerSetting["InstanceId"]}"); | ||
+ | // 你可以添加更多屬性來查看 | ||
+ | } | ||
+ | } | ||
+ | }</sxh> | ||
+ | ===== 設定電源狀態 ===== | ||
+ | * 在 C# 中直接更改電源設定是相對複雜的。你通常需要使用 P/Invoke 調用 Windows API 來實現這一點。以下是一個設置系統進入睡眠狀態的示例: | ||
+ | * <sxh c#>using System; | ||
+ | using System.Runtime.InteropServices; | ||
+ | |||
+ | class Program | ||
+ | { | ||
+ | [DllImport("user32.dll")] | ||
+ | [return: MarshalAs(UnmanagedType.Bool)] | ||
+ | public static extern bool SetSuspendState(bool hiberate, bool forceCritical, bool disableWakeEvent); | ||
+ | |||
+ | static void Main() | ||
+ | { | ||
+ | // 進入睡眠狀態 | ||
+ | SetSleep(); | ||
+ | } | ||
+ | |||
+ | static void SetSleep() | ||
+ | { | ||
+ | SetSuspendState(false, true, true); | ||
+ | } | ||
+ | }</sxh> | ||
+ | ===== 進入關機或重啟 ===== | ||
+ | * 要關閉或重啟系統,可以使用 `Process` 類來調用命令行指令: | ||
+ | * <sxh c#>using System.Diagnostics; | ||
+ | |||
+ | class Program | ||
+ | { | ||
+ | static void Main() | ||
+ | { | ||
+ | // 關機 | ||
+ | Shutdown(); | ||
+ | | ||
+ | // 重啟 | ||
+ | // Restart(); | ||
+ | } | ||
+ | |||
+ | static void Shutdown() | ||
+ | { | ||
+ | Process.Start("shutdown", "/s /t 0"); | ||
+ | } | ||
+ | |||
+ | static void Restart() | ||
+ | { | ||
+ | Process.Start("shutdown", "/r /t 0"); | ||
+ | } | ||
+ | }</sxh> | ||
+ | ===== 注意: ===== | ||
+ | * 需要適當的權限:上述涉及到系統設置和關機的操作需要管理員權限,因此確保你的應用有運行這些操作的權限。 | ||
+ | * 可能影響用戶體驗:在應用中使用這些功能時,要考慮用戶的體驗,不要隨意關機或重啟系統。 | ||
+ | * 測試:建議在開發和測試環境下進行充分的測試,以避免意外影響生產環境。 | ||
+ | * 這能幫助獲取和設定 Windows 的各種狀態。 | ||
