当开发时某些软件具有特定的日期格式，需要设置系统日期格式，保证软件正常运行。
DllImport需要using System.Runtime.InteropServices;
[DllImport("kernel32.dll", EntryPoint = "SetLocaleInfoA")] public static extern int SetLocaleInfo(int Locale, int LCType, string lpLCData); [DllImport("user32.dll", EntryPoint = "SendMessageTimeout")] public static extern long SendMessageTimeout(int hWnd, int Msg, int wParam, int lParam, int fuFlags, int uTimeout, ref int lpdwResult); [DllImport("User32.dll", EntryPoint = "PostMessage")] public static extern int PostMessage( int hWnd, // handle to destination window int Msg, // message int wParam, // first message parameter int lParam // second message parameter );
public const int LOCALE_USER_DEFAULT = 0x0400; public const int LOCALE_SYSTEM_DEFAULT = 0x0800; public const int LOCALE_SSHORTDATE = 0x1F; public const int LOCALE_STIMEFORMAT = 0x1003; public const int HWND_BROADCAST = 0xFFFF; public const int WM_SETTINGCHANGE = 0x001A; public const int SMTO_ABORTIFHUNG = 2;
public static void SetDateTimeFormat() { int p = 0; //设置短日期格式 SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SSHORTDATE, "yyyy-MM-dd"); //设置时间格式，24小时制 SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_STIMEFORMAT, "HH:mm:ss"); //设置完成后必须调用，通知其他程序格式已经更改，否则即使是程序自身也不能使用新设置的格式 SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, 0, SMTO_ABORTIFHUNG, 10,ref p); }
