How to Programmatically Refresh Internet Explorer Web Pages Using C#?

C#programming two methods to refresh the IE webpage

This article introduces two methods to automatically refresh the Internet Explorer webpage: Simulation buttons and directly send messages.

Method 1: Simulation F5 button

Using the Simulation F5 button, you can send the keyboard input to any application without causing it to be at the front desk. The following code example demonstrates how to refresh the IE webpage:

This code will cycle to find all the open IE processes and send the F5 button to it to refresh the current webpage. SendKeys

Method 2: Send the message directly

<code class="language-csharp">using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;

static class Program
{
    [DllImport("user32.dll")]
    public static extern int SetForegroundWindow(IntPtr hWnd);

    [STAThread]
    static void Main()
    {
        while (true)
        {
            Process[] processes = Process.GetProcessesByName("iexplore");
            foreach (Process proc in processes)
            {
                SetForegroundWindow(proc.MainWindowHandle);
                SendKeys.SendWait("{F5}");
            }
            Thread.Sleep(5000);
        }
    }
}</code>

Use the function to directly send the key message. There is no need to set the application as the front desk window, which is more efficient and will not interrupt the user's current operation.

This method directly sends the VK_F5 keys, and it is more efficient without setting the front desk window. Please note that these two methods use cycles and refresh the page every 5 seconds. In practical applications, the refreshing frequency may need to be adjusted according to specific needs.
