On a Button click i'm opening a default browser with a desired Url.

I want that in a loop inputted by the user it will have "F5" command executed that number of times.

I am able to open the number of tabs should open in default browser but not the number of times it should refresh itself.

Accepted answer
So, a few things of note that stick out:

1) Are you sure that the window you want to have the keys sent has focus?
2) What O/S are you using? You may need to set the app.config to specify either "SendInput" (new implementation) or "JournalHook" (old implementation)
3) When using the "^" (ctrl) key, I believe you need to wrap the remainder in parenthesis, so it would be like this: "^(s)"
4) Do you have the ability to use Spy++ to see what commands are being sent to the windows?

Sir, I had tried with almost everything but nothing is working i had used SendKeys() as well as winapi32 but both of them didnt worked for my code..

My application is in MVVM-WPF Arch.

[DllImport("User32.dll")]
public static extern int SetForegroundWindow(IntPtr hWnd);
public void MyAction()
{
//Binding text Box property from UserViewModel to Model Classes
_UrlList.Add(new MPingo() { Url = Url });
Process[] proc = Process.GetProcessesByName("chrome");
foreach (Process proci in proc)
{
// After every 2 Seconds Chrome will open a new tab with the given Url
Process strt = Process.Start("chrome.exe", Url);
SetForegroundWindow(proci.MainWindowHandle);
Thread.Sleep(200);
SendKeys.SendWait("^s");
SendKeys.SendWait("{F5}");

}
}

Even it is not activating the current window and sending f5 command

Are you looking to do the 'F5' command from WPF? If so, this stack overflow link may help you: Directly sending keystrokes to another process via hooking

If you are open to using an external library the Windows Input Simulator is another avenue that abstracts the logic used in the stack overflow link. You could wrap it up in a loop and call it as much as you want.
