Question

I'm making the application of Google Chrome. In C# I do not know how to get the tab title.

I like the tab to appear under image the title I want to.

but, my code is gets only active tabs title.(another tabs title is displaying nothing)

foreach (Process process in Process.GetProcessesByName("chrome"))
{
    Console.WriteLine(process.MainWindowTitle);
}

How can get every title of chrome tabs?
