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

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;

}
