如何在修改web.config时阻止ASP.NET应用程序重新启动？

<appSettings>
  <add key="myKey" value="myValue"/>
</appSettings>

string myValue = ConfigurationManager.AppSettings["myKey"];

string siteName = "MySite"; // 站点名称
string configPath = "C:\\inetpub\\wwwroot\\MySite\\web.config"; // Web.config文件路径
string tempConfigPath = "C:\\temp\\temp.config"; // 临时文件路径

// 将Web.config文件另存为临时文件
File.Copy(configPath, tempConfigPath, true);

// 使用appcmd.exe命令行工具将临时文件与Web.config文件进行合并
ProcessStartInfo startInfo = new ProcessStartInfo("appcmd.exe", string.Format("recycle apppool /apppool.name:\"{0}\"", siteName));
using (Process process = Process.Start(startInfo))
{
    process.WaitForExit();
}

startInfo = new ProcessStartInfo("appcmd.exe", string.Format("sync apppool /apppool.name:\"{0}\"", siteName));
using (Process process = Process.Start(startInfo))
{
    process.WaitForExit();
}

startInfo = new ProcessStartInfo("appcmd.exe", string.Format("recycle apppool /apppool.name:\"{0}\"", siteName));
using (Process process = Process.Start(startInfo))
{
    process.WaitForExit();
}

// 删除临时文件
File.Delete(tempConfigPath);
