WinCE系統獲取遠程服務器時間來設置本地時間

　　在做項目時用datalogic手持終端設備遇到一個問題，系統冷啓動或斷電後再啓動這時系統的時間會還原掉，當然重新設置系統時間這是沒問題的，但就是有點麻煩，每次都要設置，如果我們限制手持機的使用功能，比如說鎖住桌面不讓用戶做其它操作，這時用戶根本就沒辦法手動設置系統時間，那能不能能過代碼獲取遠程服務器時間來設置本地時間呢？可通過ＡＰＩ來修改系統的時間，代碼如下：
1.　[b]聲明代碼[/b]

       //imports SetLocalTime function from kernel32.dll 
       [DllImport("coredll.dll", SetLastError = true)]
       public static extern int SetLocalTime(ref SystemTime lpSystemTime);
       //struct for date/time apis 
       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;
       }

2.　[b]調用代碼示例：[/b]

try
{
    // 通過WebService獲取服務器時間
    SCM.SOAPService soap = new SCM.SOAPService();
    DateTime remoteTime = soap.getSystemTime();
    // 給結構體賦值
    SystemTime newTime = new SystemTime();
    newTime.wYear = (short)remoteTime.Year;
    newTime.wMonth = (short)remoteTime.Month;
    newTime.wDay = (short)remoteTime.Day;
    newTime.wHour = (short)remoteTime.Hour;
    newTime.wMinute = (short)remoteTime.Minute;
    newTime.wSecond = (short)remoteTime.Second;
    newTime.wMilliseconds = (short)remoteTime.Millisecond;
    newTime.wDayOfWeek = (short)remoteTime.DayOfWeek;
    // 設置本地時間
    SetLocalTime(ref newTime);
}
catch 
{
    MessageBox.Show("獲取服務器時間設置本地時間失敗！", "錯誤提示",MessageBoxButtons.OK, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1);
}
