How to check if application is running [duplicate]

Question

I just want to check if any desired application is already running or not

for eg suppose I have VLC or iTunes or any windows application then how can i figure it out by c# code if it is running or not.

Answer 1

This should be pretty easy to find with a quick Google search, but here you go:

if (Process.GetProcessesByName("process_name").Length > 0)
{
    // Is running
}

Replace process_name with the name of the process you are looking for (i.e. vlc).

Checking for Self-Process

As pointed out in the comments by @filimonic, if you want to check whether more than one instance of the application is running you can use > 1 in place of > 0:

if (Process.GetProcessesByName("process_name").Length > 1)
{
    // Is running
}

This works by checking that a maximum of 1 processes is currently running.

Answer 2

you can use either Process.GetProcessesByName if you know the process name or Process.GetProcessesByID if you know it's ID.
