Question

I have a requirement to change System s date time from UWP app. I am trying below methods but it is not working. Same methods works if I run from Console App.

    [StructLayout(LayoutKind.Sequential)]
    public struct SYSTEMTIME
    {
        public short wYear;
        public short wMonth;
        public short wDayOfWeek;
        public short wDay;
        public short wHour;
        public short wMinute;
        public short wSecond;
        public short wMilliseconds;
    }

    [DllImport("kernel32.dll", SetLastError = true)]
    public static extern SYSTEMTIME GetSystemTime();
    
    public void ChangeDateTime()
    {
                SYSTEMTIME a = GetSystemTime();
                SYSTEMTIME st = new SYSTEMTIME();
                st.wYear = (short)a.wYear;
                st.wMonth = (short)a.wMonth;
                st.wDay = (short)a.wDay;
                st.wHour = (short)a.wHour;
                st.wMinute = (short)(a.wMinute + 5);
                st.wSecond = (short)a.wSecond;
                st.wMilliseconds = (short)a.wMilliseconds;

                bool i = SetSystemTime(ref st);
    }

SetSystemtime回报不实,日期没有生效。

我是否失踪了,或者有什么其他办法去做?

根据文件SetSystemtime ,这一方法只使用 desktop。预计这一方法不会在UWP中发挥作用。

铀料在沙箱中运行,获得系统资源的机会有限。有一个可确定系统日期的本地的“UWP”样本:DatetimeSettings.SetSystemDatetime(Datetime)meth。但只为IOT装置设计:而不是在桌面上施工。

唯一的方式是,你可以使用青.器。然后从UWP射线发射ole。您可尝试提及Stefan sblog 如何执行:https://stefanwick.com/2018/04/06/uwp-with-desktop-extension-part-1/。
