C # open a webpage using the default browser

In the C # winformProgramIf we want to open a webpage, we usually use
System. Diagnostics. process. Start ("iexplore. EXE ", Http://www.lanmeng.org/ );
Or
Webbrowser web_new = new webbrowser ();
Web_new.navigate (" Http://www.lanmeng.org ");
However, we can only open the webpage with IE, but we do not want to open the webpage with the default browser of the system, such as Chrome browser, sogou browser or Baidu browser.
String target =" Http://www.lanmeng.org/ ";
Try
{
System. Diagnostics. process. Start (target );
}
Catch (system. componentmodel. win32exception nobrowser)
{
If (nobrowser. errorcode ==- 2147467259)
MessageBox. Show (nobrowser. Message );
}
Catch (system. Exception other)
{
MessageBox. Show (other. Message );
}
