How to maximize the browser window in Selenium WebDriver (Selenium 2) using C#?

Question

Is there any way to maximize the browser window using WebDriver (Selenium 2) with C#?

Answer 1

For me, none of the solutions above worked when working with Selenium Web Driver C# + Chrome:

• window.resizeTo(1024, 768); - I want to use the whole screen
• --start-maximized - it is ignored
• driver.manage().window().maximize(); - does not work because it requires some extension and I am not allowed to use Chrome extensions

I managed to get it working using InputSimulator:

var inputSim = new InputSimulator();
// WinKey + UP = Maximize focused window
inputSim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.UP);
