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;
 
 }
