把寫代碼過程重要的代碼段珍藏起來,如下的代碼內容是關於C# 程序自動升級的的代碼。

2、在WinForm應用程序啓動的時候,首先訪問webservice獲取服務器的xml中的版本號,然後獲取客戶端的xml中的版本號。將兩個版本號比較,若服務器中的版本號大,則提示提示可以在線更新應用程序。3、然後客戶端自動下載網絡上的zip壓縮包到本機的指定位置,進行自動解壓縮到安裝的目錄進行覆蓋。解壓縮完畢之後,用進程打開所解壓過的exe文件進行軟件安裝。同時關閉客戶端軟件所在的進程。4、注意:升級程序和應用程序都是單獨的,應用程序在使用時不能對本身進行升級(覆蓋會失敗)。具體代碼如下:第一部分應用程序如口Program:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using Medicine_ERP;
using DevExpress.XtraEditors;
using System.Xml;
using Anshield_AutoFutures.BaseClase;
namespace Anshield_AutoFutures
{
static class Program
{
private static void LoadMath()
{
string NewEdition = "1.0";
string OldEdition = "1.0";
try
{
NewEdition = webserverClase.getCopyRightCode();
String fileName = Application.StartupPath + "\XMLEdition.xml";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fileName);
XmlNode xn = xmlDoc.SelectSingleNode("Content");
XmlNodeList xnl = xn.ChildNodes;
foreach (XmlNode xnf in xnl)
{
XmlElement xe = (XmlElement)xnf;
if (xe.GetAttribute("id") == "jigou_plz")
{
}
break;
}
double newE = double.Parse(NewEdition);
double oldE = double.Parse(OldEdition);
if (newE > oldE)
{
DialogResult dr = XtraMessageBox.Show("發現新的版本是否要更新該軟件", "平浪舟現貨程序化交易--更新提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
if (dr == DialogResult.OK)
{
System.Diagnostics.Process.Start(Application.StartupPath + @"Upgrade_Form.exe");
Application.Exit();
}
else
{
anshield_Login login = new anshield_Login();
if (login.ShowDialog() == DialogResult.OK)
{
Application.Run(new Main_AutoFutures());
}
}
}
else
{
anshield_Login login = new anshield_Login();
if (login.ShowDialog() == DialogResult.OK)
{
Application.Run(new Main_AutoFutures());
}
}
}
catch
{
XtraMessageBox.Show("網絡鏈接失敗!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
[STAThread]
static void Main()
{
System.Threading.Mutex mutexMyapplication = new System.Threading.Mutex(false, "jigou_plz.exe");
if (!mutexMyapplication.WaitOne(100, false))
{
XtraMessageBox.Show("程序" + Application.ProductName + "已經在運行!", "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
return;
}
else
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
hugengyong hu = new hugengyong();
DevExpress.UserSkins.OfficeSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();
DevExpress.UserSkins.BonusSkins.Register();
LoadMath();
}
}
}
}
第二部分:升級程序代碼如下:
string path = Application.StartupPath;
private void btnDown_Click(object sender, EventArgs e)
{
string zipFile = path + @"jigou_plz.zip";
killProess();
btnDown.Enabled = false;
button2.Enabled = false;
try
{
string downUrl = ConfigurationManager.ConnectionStrings["DownUrl"].ConnectionString.ToString().Trim();
if (!string.IsNullOrEmpty(downUrl))
{
DownloadFile(downUrl, zipFile, progressBar1, label1);
}
else
{
MessageBox.Show("Config中的下載路徑配置錯誤!", "錯誤", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
}
catch
{
MessageBox.Show("當前沒有網絡或者文件地址不正確");
return;
}
try
{
killProess();
BaseClase.Zip.UnZip(zipFile, path, "", true,true);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
return;
}
if (MessageBox.Show("升級完成!,請重新登陸!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information) == DialogResult.OK)
{
if (file.Exists)
{
Process.Start(path + @"Anshield_AutoFutures.exe");
}
Application.Exit();
}
}
public void DownloadFile(string URL, string filename, System.Windows.Forms.ProgressBar prog, System.Windows.Forms.Label label1)
{
float percent = 0;
try
{
System.Net.HttpWebRequest Myrq = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(URL);
System.Net.HttpWebResponse myrp = (System.Net.HttpWebResponse)Myrq.GetResponse();
long totalBytes = myrp.ContentLength;
if (prog != null)
{
prog.Maximum = (int)totalBytes;
}
System.IO.Stream st = myrp.GetResponseStream();
System.IO.Stream so = new System.IO.FileStream(filename, System.IO.FileMode.Create);
long totalDownloadedByte = 0;
byte[] by = new byte[1024];
int osize = st.Read(by, 0, (int)by.Length);
while (osize > 0)
{
totalDownloadedByte = osize + totalDownloadedByte;
System.Windows.Forms.Application.DoEvents();
so.Write(by, 0, osize);
if (prog != null)
{
prog.Value = (int)totalDownloadedByte;
}
osize = st.Read(by, 0, (int)by.Length);
label1.Text = "下載進度" + percent.ToString() + "%";
}
label1.Text = "下載完成。安裝中... ...";
so.Close();
st.Close();
}
catch (System.Exception)
{
throw;
}
}
private void killProess()
{
this.label1.Text = "正在關閉程序....";
System.Diagnostics.Process[] proc = System.Diagnostics.Process.GetProcessesByName("Anshield_AutoFutures");
foreach (System.Diagnostics.Process pro in proc)
{
pro.Kill();
}
}
