在Unity中实现简单的伪时间同步

在Unity中实现简单的伪时间同步，只是读取数据库所在电脑的当前时间

代码如下:

using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;
using System.Data;
using System.Data.SqlClient;
public class ChangeTime
{
    //Kernel32.dll在32位系统和64位系统有区别，64位系统中需要设置为以管理员身份运行
    [DllImport("Kernel32.dll",SetLastError=true,EntryPoint="SetLocalTime")]
    static extern int SetLocalTime(ref SystemDateTime lpSystemDateTime);
    public static string GetCurrentTimeFromDB()
    {
        string result = "";
        //从数据库中获取系统当前时间
        //设置连接字符串
        SqlConnection con = new SqlConnection ("Data Source=192.168.0.1;Initial Catalog=DB;User ID=sa;password=123456");
        SqlCommand cmd = new SqlCommand ();
        cmd.Connection = con;
        cmd.CommandType = System.Data.CommandType.Text;
        //设置连接语句
        cmd.CommandText = "select getdate()";
        SqlDataAdapter sda = new SqlDataAdapter(cmd);
        //开启
        sda.SelectCommand.Connection.Open();
        result = sda.SelectCommand.ExecuteScalar().ToString();
        //关闭
        sda.SelectCommand.Connection.Close();
        return result;
    }
    public static void SetLocalDae(string dateTime)
    {
        System.DateTime date = System.DateTime.Parse(dateTime);
        SystemDateTime sysNew = new SystemDateTime();
        //设置属性
        sysNew.tYear = short.Parse(date.Year.ToString());
        sysNew.tMonth = short.Parse(date.Month.ToString());
        sysNew.tDay = short.Parse(date.Day.ToString());
        sysNew.tHour = short.Parse(date.Hour.ToString());
        sysNew.tMinute = short.Parse(date.Minute.ToString());
        sysNew.tSecond = short.Parse(date.Second.ToString());
        //调用API，更新系统时间
        SetLocalTime(ref sysNew);
    }
}
/// <summary>
/// 定义变量用于接收
/// </summary>
public class SystemDateTime
{
    public short tYear;
    public short tMonth;
    public short tDayOfWeek;
    public short tDay;
    public short tHour;
    public short tMinute;
    public short tSecond;
    public short tMilliseconds;
}
