winform應用程式自動更新版本
我現在做的是由更新程式來更新winform程式,但是最後的目的是想winform自己本身能夠更新吧,還是沒找到好的方法,現記錄下有update.exe來更新winform.exe。
1.先建一個記錄有版本資訊的xml檔案,update.xml
其中的程式碼如下:
<root xmlns="">
<module>
<moduleName>BLL.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/BLL.dll</appUrl>
</module>
<module>
<moduleName>DAL.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/DAL.dll</appUrl>
</module>
<module>
<moduleName>winform.exe</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/demo.exe</appUrl>
</module>
<module>
<moduleName>Model.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/Model.dll</appUrl>
</module>
<module>
<moduleName>RdCard.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/RdCard.dll</appUrl>
</module>
<module>
<moduleName>sdtapi.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/sdtapi.dll</appUrl>
</module>
<module>
<moduleName>WltRS.dll</moduleName>
<version>4.0</version>
<appUrl>http://10.77.150.105:7003/webservice/Release/Wltrs.dll</appUrl>
</module>
</root>
update.xml是放在已經部署的webservice資料夾下的。
下面是update.exe程式碼:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.IO;
namespace Update
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
System.Diagnostics.Process[] ps = System.Diagnostics.Process.GetProcesses();
foreach (System.Diagnostics.Process p in ps)
{
//MessageBox.Show(p.ProcessName);
if (p.ProcessName.ToLower() == "winform")//停止所有叫"winform"的程式
{
p.Kill();
break;
}
}
string path = Application.StartupPath;
this.VersionCheck(path, "
}
public string GetVer()//獲得版本號
{
XmlDocument doc = new XmlDocument();
doc.Load(@"update.xml");
XmlElement root = doc.DocumentElement;
return root.SelectSingleNode("version").InnerText;
}
private void DownloadFile(string source, string fileName)//下載更新檔案
{
try
{
System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.DownloadFile(source, fileName);
}
catch (Exception ex)
{
throw new Exception("下載失敗,原因是:" + ex.Message, ex);
}
}
private void VersionCheck(string desPath, string webServiceAddress)//版本號校驗
{
try
{
#region 檢視檔案和目錄
if (!desPath.EndsWith(@"/"))
desPath += @"/";
if (!System.IO.Directory.Exists(desPath))
{
System.IO.Directory.CreateDirectory(desPath);
}
string tempPath = desPath + @"update/";
if (System.IO.Directory.Exists(tempPath))
{
System.IO.Directory.Delete(tempPath, true);
System.IO.Directory.CreateDirectory(tempPath);
}
else
System.IO.Directory.CreateDirectory(tempPath);
if (!System.IO.File.Exists(desPath + "UpdateConfig.xml"))
{
System.Xml.XmlDocument updateConfig = new System.Xml.XmlDocument();
updateConfig.LoadXml(@"<root></root>");
updateConfig.Save(desPath + "UpdateConfig.xml");
}
#endregion
localhost.MyService appUpdate = new localhost.MyService();
//WebService appUpdate = new WebService();
appUpdate.Url = webServiceAddress;
//System.Xml.XmlDocument serverXmlDoc = ((System.Xml.XmlDocument)appUpdate.AppUpdateVertion());
// System.Xml.XmlDocument serverXmlDoc = appUpdate.AppUpdateVertion();
System.Xml.XmlDocument serverXmlDoc = new XmlDocument();
//serverXmlDoc.LoadXml();
//System.Xml.XmlDocument serverXmlDoc = appUpdate.AppUpdateVertion();
System.Xml.XmlNode xml = appUpdate.AppUpdateVertion();
serverXmlDoc.LoadXml(xml.OuterXml);
System.Xml.XmlDocument localXmlDoc = new System.Xml.XmlDocument();
localXmlDoc.Load(desPath + "UpdateConfig.xml");
bool newVersionExist = false;
bool moduleExist = false;
System.Xml.XmlNode serverNode0 = serverXmlDoc.ChildNodes[0];
System.Xml.XmlNode localNode0 = localXmlDoc.ChildNodes[0];
foreach (System.Xml.XmlNode serverNode in serverNode0)
{
moduleExist = false;
foreach (System.Xml.XmlNode localNode in localNode0)
{
//找到對應模組
if (localNode.ChildNodes[0].InnerText == serverNode.ChildNodes[0].InnerText)
{
moduleExist = true;
//版本號判斷
if (localNode.ChildNodes[1].InnerText.CompareTo(serverNode.ChildNodes[1].InnerText) < 0)
{
newVersionExist = true;
DownloadFile(serverNode.ChildNodes[2].InnerText, tempPath + serverNode.ChildNodes[0].InnerText);
}
break;
}
}
//沒找到對應模組
if (false == moduleExist)
{
DownloadFile(serverNode.ChildNodes[2].InnerText, tempPath + serverNode.ChildNodes[0].InnerText);
newVersionExist = true;
}
}
//寫入新UpdateConfig.xml升級完畢後替換
if (newVersionExist)
{
serverXmlDoc.Save(tempPath + "UpdateConfig.xml");
if (DialogResult.Yes == MessageBox.Show("有新版本,升級否", "提示", MessageBoxButtons.YesNo))
{
string[] dirs = System.IO.Directory.GetFiles(tempPath, "*.*");
string fileName;
foreach (string dir in dirs)
{
fileName = ((dir.Split(Convert.ToChar(@"/")))[dir.Split(Convert.ToChar(@"/")).Length - 1]);
if (System.IO.File.Exists(desPath + fileName))
{
//TODO:可以支援備份以前版本
//System.Diagnostics.Process.Start(Application.StartupPath + @"\demo.exe");
//System.Diagnostics.Process[] ps = System.Diagnostics.Process.GetProcesses();
System.IO.File.Delete(desPath + fileName);
}
//TODO:如果系統正在執行,您得停止系統,至於如何停止,也許可以使用System.Diagnostics.Process
System.IO.File.Move(dir, desPath + fileName);
}
MessageBox.Show("升級完畢");
}
else
{
//TODO:可以支援重新提示升級
}
}
}
catch (Exception ex)
{
throw new Exception("升級失敗,原因是:" + ex.Message, ex);
}
System.Diagnostics.Process.Start("demo.exe");
Close();
Application.Exit();
}
}
}
update.exe還需要新增引用webservice,webservice上面的程式碼:
[WebMethod(Description = "讀伺服器上關於程式各個版本資訊的配置檔案UpdateConfig.xml")]
public System.Xml.XmlDocument AppUpdateVertion()
{
System.Xml.XmlDocument xml = new System.Xml.XmlDocument();
xml.Load(CurrentPath("/webs1") + @"/UpdateConfig.xml");
return xml;
}
private string CurrentPath(string virtualPath)
{
return HttpContext.Current.Server.MapPath(virtualPath);
}
主要原理是,停止所有的winform.exe,update會建一個資料夾叫update(在程式的Update\bin\Debug目錄下),先判斷版本號,如果版本號比原來的大,則更新,若不是,則執行原版本的應用程式,若有新的版本,就會,update資料夾內是存放下載的新的版本的winform.exe和其他檔案,之後,刪除update.exe資料夾的debug資料夾下的相對的資料夾,然後將update資料夾下面的檔案移出到debug資料夾下面,最後啟動winform.exe。
