基于c#的IE 代理服务器设置
在进行IE代理服务设置时，需要手动打开代理服务器以及设置IE浏览器代理设置、开启或关闭。此处利用c#编写窗体，一键打开代理服务器、设置IE代理。此程序是基于一改进方案进行开发。一般的做法是直接修改注册表进行IE代理的设置，但是需要重启浏览器才能生效，改进方案中修正这一弊端，在浏览器运行时就能正常设置代理，但是不涉及代理服务器。此程序可以调用已经配置好的代理服务器，在开启代理后，能直接访问需要代理的网站，此程序经过安装部署处理。
主要程序的将在最后显示。
以下记录使用的部分程序：
1.计算已使用此代理程序时间：
DateTime start_time = DateTime.Now; private void show_timer_Tick(object sender, EventArgs e)
{
DateTime time_now = DateTime.Now;
date_label.Text = time_now.ToShortDateString();
time_label.Text = time_now.ToShortTimeString();
TimeSpan time_begin = new TimeSpan(start_time.Ticks);
TimeSpan time_end= new TimeSpan(time_now.Ticks);
TimeSpan time_span = time_end.Subtract(time_begin).Duration();
usedTime_label.Text ="Used "+ time_span.Hours.ToString() + " hours" + " "+time_span.Minutes.ToString() + " mins";
}
2， 获取计算机的有关信息，电脑名，用户名，处理器数量，电脑物理地址，操作系统版本，运行时的共同语言（基本不需要）。
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog;
this.MaximizeBox = false;
computer_info_listBox.Items.Add("computer name:" );
computer_info_listBox.Items.Add( Environment.MachineName);
computer_info_listBox.Items.Add("user name:" );
computer_info_listBox.Items.Add( Environment.UserName);
computer_info_listBox.Items.Add("processor count:" );
computer_info_listBox.Items.Add( Environment.ProcessorCount);
computer_info_listBox.Items.Add("computer mac address:");
computer_info_listBox.Items.Add( GetNetworkAdapterID());
computer_info_listBox.Items.Add("Operation system version:" );
computer_info_listBox.Items.Add(Environment.OSVersion);
computer_info_listBox.Items.Add("common language running:");
computer_info_listBox.Items.Add(Environment.Version);
其中，获取电脑物理地址调用了自定义的函数。函数定义如下
public static string GetNetworkAdapterID()
{
string mac = "";
ManagementClass mc = new ManagementClass("Win32_NetWorkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"]==true)
mac = mo["MacAddress"].ToString();
}
return mac;
}
3.打开，关闭代理服务器程序
打开代理服务器
打开代理服务器
将代理服务器文件放在debug文件下，包括.exe文件。然后在开启IE代理设置的同时，执行此程序。
System.Diagnostics.Process.Start(@".\proxyfile\local\proxy.exe");
关闭代理服务器程序
public void KillProcess(string ProName)
{
Process[] Goagent_proxy = Process.GetProcessesByName(ProName);
foreach(Process p_kill in Goagent_proxy)
{
p_kill.Kill();
}
}
此处主要使用 process 类，具体使用可以参考相关文档。
4.关闭messagebox执行事件。此处是打开一网址。
DialogResult message_Result= MessageBox.Show("Step1: Import certificate from goagent, detail operation,see:" + "\n" + " when you click the OK below,you will see the article " +"\n"+"Step2: click setting proxy button in the interface", "Instruction",MessageBoxButtons.OK);
if (message_Result == DialogResult.OK)
{
Process.Start("http://jingyan.baidu.com/article/8275fc869f1c0c46a03cf6e9.html ");
}
}
5 安装部署
此处使用的visual studio2012版，与2010版不同，需要手动下载InstallShiled.步骤如下；
打开 VS， new -- project -- Installed--template--other Project Types --Setup and Deployment ,选择ok后者中间的 InstallShield Limited Edition Project，将在浏览器中打开下载改程序的网页，在右侧填写相关信息。然后下载。
注意，若国家、城市等无法打开下拉选框进行填写时，表明这是Great Wall 在发挥作用，解决办法是使用代理服务器打开此页面。
后面的步骤就是下载安装 InstallShield。 注意，安装之前要关闭VS，同时，右键安装程序，以管理员身份运行。
完成后，按照之前的步骤重新操作，即可。
