C# calling the Process.Start() create another instance of the program

Question

this is my first post here so forgive me for my mistakes. I'm currently developping a program for myself. It is a C# winform app. You just fill the hours/minutes/seconds input and I then want it to shutdown the computer at that given amount of time later. So I coded the basics to convert the amount of time in seconds ( as the batch only accepts seconds ). I even ran the .exe in a windows 10 virtual machine but There's a problem with my call :

private void btnValidate_Click(object sender, EventArgs e)
        {
           seconds =  convertToSeconds();
           Process.Start("shutdown", "/s /t " + seconds);
        }

Calling this function just run another instance of this .exe. at first, I thought it was because adding "+ seconds" was wrong and there was another way of doing it but even cancelling the shutdown with this code runs another instance of the .exe :

 private void button1_Click(object sender, EventArgs e)
        {
            long seconds = 0;
            DateTime shutdownDate = default(DateTime);
            Process.Start("shutdown", "/a");
        }

Here is a screenshot of the app if you didn't understand how it works : http://puu.sh/qkUi0/f2c1ad00ad.png

Thanks in advance for helping me.

You might be better off using a process start info parameter instead of strings [see the docs](https://msdn.microsoft.com/en-us/library/system.diagnostics.process.start(v=vs.110).aspx) — D. Ben Knoble, Jul 31 '16 at 16:10

I am guessing your application name is also shutdown.exe. Is it? — Sandeep Singh Rawat, Jul 31 '16 at 17:00

Oh my god yes it is. I knew I made a dumb mistake. Let me rename everything and give you an update — JiggyJinjo, Jul 31 '16 at 17:05
