Hi,

I need to Close / Kill the already opened Main WinForm application through C# coding, and will support all the operating system (Win 7 32 & 64 bit, Vista 32 & 64 Bit etc.).

I already tried the below code but some times it didn't work in XP.
And rest OS this is not working. Please find below code:

C#

Process thisProc = null;
string processName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
            
foreach (Process openedProcesses in Process.GetProcesses())
{
	if (openedProcesses.ProcessName.Contains(processName))
	{
		thisProc = openedProcesses;
		thisProc.CloseMainWindow();
		thisProc.Kill();
	}
}

Thanks in advance.

What type of scenario are you describing here: what type of processes has your Windows Form application created, or invoked, that are not, now, terminated by Appliction.Exit() ?

Solution 1

Use Application.Exit() if you are calling from inside your application.

C#

Process thisProc = null;
string processName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
            
foreach (Process openedProcesses in Process.GetProcesses())
{
	if (openedProcesses.ProcessName.ToLower().Contains(processName.ToLower()))
	{
		thisProc = openedProcesses;
		//thisProc.CloseMainWindow();
		thisProc.Kill();
	}
}

It is not with the same instance.
We want with different instance.
