How to safely close Google Chrome programmatically

Question

How can i safely close google chrome via C#? I can kill chrome process, but in this case Google Chrome will report appcrash on next run.

Get a handle to Chrome's windows and send `WM_CLOSE` to each of them: http://stackoverflow.com/questions/1129204/how-to-use-wm-close-in-c — Jon, Jan 23 '13 at 12:28

I am just curious... by default google chrome or any other browser would alert me that an application is trying to close the browser? Thinking as a user I think this is a very annoying process. Most of the time I have so many tab´s opened and I just don´t want to close everything. As each tab has its own process, would not be better to close a specific tab instead of the whole browser? — Guilherme Longo, Jan 23 '13 at 12:34
@Guilherme I need to close browser, because I need to modify SQLite Chrome database(set my default search provider). — user2003858, Jan 23 '13 at 12:43
I did not know we could manipulate Chrome database. Now that you said it make sense that you close the browser. — Guilherme Longo, Jan 23 '13 at 13:10

You could use the little known UI Automation API, like this:

static void CloseAllChromeBrowsers()
{
    foreach (Process process in Process.GetProcessesByName("chrome"))
    {
        if (process.MainWindowHandle == IntPtr.Zero) // some have no UI
            continue;

        AutomationElement element = AutomationElement.FromHandle(process.MainWindowHandle);
        if (element != null)
        {
            ((WindowPattern)element.GetCurrentPattern(WindowPattern.Pattern)).Close();
        }
    }
}

Unfortunatly if you have multiple chrome windows open this will not close the first one. – KVM Dec 01 '13 at 21:46

Worked well for me!! Thanks Simon. Namespaces required: using System.Diagnostics, using System.Windows.Automation – Tom Martin Mar 10 '16 at 18:15

I had to reference UIAutomationClient and UIAutomationTypes. – PRMan Mar 11 '17 at 19:42

You could try to determine the window handle(s) using the Process class and send a WM_CLOSE message to the window.
