lac linq generic ray [1] 常用 seq update etime 做工程過程,將做工程過程經常用的內容做個收藏,下面內容內容是關於 C#同步網絡時間和本地時間的內容,希望對各位朋友有較大用途。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text.RegularExpressions;
using System.Runtime.InteropServices;
using System.Runtime;
public class NetTime { public DateTime GetBeijingTime() { DateTime dt; WebRequest wrt = null; WebResponse wrp = null; try { wrp = wrt.GetResponse(); string html = string.Empty; using (Stream stream = wrp.GetResponseStream()) { using (StreamReader sr = new StreamReader(stream, Encoding.UTF8)) { html = sr.ReadToEnd(); } } string[] tempArray = html.Split(‘;‘); for (int i = 0; i < tempArray.Length; i++) { tempArray[i] = tempArray[i].Replace("rn", ""); } string year = tempArray[1].Split(‘=‘)[1]; string month = tempArray[2].Split(‘=‘)[1]; string day = tempArray[3].Split(‘=‘)[1]; string hour = tempArray[5].Split(‘=‘)[1]; string minite = tempArray[6].Split(‘=‘)[1]; string second = tempArray[7].Split(‘=‘)[1]; dt = DateTime.Parse(year + "-" + month + "-" + day + " " + hour + ":" + minite + ":" + second); } catch (WebException) { return DateTime.Parse("2011-1-1"); } catch (Exception) { return DateTime.Parse("2011-1-1"); } finally { if (wrp != null) wrp.Close(); if (wrt != null) wrt.Abort(); } return dt; } }
獲取網絡時間,返回一個DateTime對象,然後傳給設置系統時間的方法,修改系統時間。同步系統時間:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text.RegularExpressions;
using System.Runtime.InteropServices;
using System.Runtime;
public class UpdateTime { [DllImport("kernel32.dll")] private static extern bool SetLocalTime(ref SYSTEMTIME time); [StructLayout(LayoutKind.Sequential)] private struct SYSTEMTIME { public short year; public short month; public short dayOfWeek; public short day; public short hour; public short minute; public short second; public short milliseconds; } public static bool SetDate(DateTime dt) { SYSTEMTIME st; st.year = (short)dt.Year; st.month = (short)dt.Month; st.dayOfWeek = (short)dt.DayOfWeek; st.day = (short)dt.Day; st.hour = (short)dt.Hour; st.minute = (short)dt.Minute; st.second = (short)dt.Second; st.milliseconds = (short)dt.Millisecond; bool rt = SetLocalTime(ref st); return rt; } }
兩個方法分別寫在了兩個類裏面,只需要在客戶端實例化兩個對象,然後依次調用其方法即可,簡單實用。
