Send data to a website using Microsoft Edge (switching from Internet Explorer)

Question

I have this existing Windows form application written in C# that processes data and send the proccessed data to a website.

It is working fine in internet explorer but I want to it also to work on Microsoft Edge. is it possible to use Edge?

Here's my code.

   private void SendDataToSPC(SHDocVw.InternetExplorer ie, string strSPCData)
        {           
            mshtml.IHTMLDocument3 doc = ie.Document as mshtml.IHTMLDocument3;
            mshtml.IHTMLElementCollection txtBoxes = doc.getElementsByTagName("INPUT");
            string[] data = Regex.Split(strSPCData, "\r\n");
            int intCtr = 0;
            foreach (mshtml.IHTMLElement txtBox in txtBoxes)
            {
                if (txtBox.getAttribute("className") != null)
                {
                    if (txtBox.getAttribute("className").Equals("vcs_de_textbox") && intCtr < data.Length)
                    {
                        txtBox.setAttribute("value", data[intCtr]);
                        intCtr++;
                    }
                }
            }

            foreach (mshtml.IHTMLElement button in txtBoxes)
            {
                if (button.getAttribute("className") != null)
                {
                    if (button.getAttribute("className").Equals("vcs_de_saveButton")){
                        button.click();
                    }
                }
            }

            ((mshtml.HTMLDocument)doc).focus();
        }

Update

I currently using Selenium and I try to use Edge driver it returns me an error of

Additional information: A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:58191/session. The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive.

But when I try to use firefoxDriver it is working but I need to use existing Firefox open browser session (existing open Firefox).

Selinium webdriver 3.141.0 
Microsoft Edge 41.16299.1480.0 - browser 
Selenium.webdriver.microsoftdrivere 17.17134.0
OS Windows 10

Here's my latest code

  private void SendDataToSPC2(string strSPCData)
        {
            //Create the reference for our browser
            //System.setProperty("webdriver.edge.driver");
            //IWebDriver driver = new FirefoxDriver();

            //Navigate to google page
            //driver.Navigate().GoToUrl("http:www.google.com");

            //Find the Search text box UI Element
            //IWebElement element = driver.FindElement(By.Id("p1d1"));

            //Perform Ops
            //element.SendKeys("executeautomation");

            //Close the browser
           // driver.Close();
            IWebDriver edgeDriver = new EdgeDriver();
            edgeDriver.Navigate().GoToUrl("http://phgcubadm1ms023/spc/jsp/dataentry/vcsdataentry/vcsDataEntryMain.action");
            var txtBoxes = edgeDriver.FindElements(By.TagName("INPUT"));
            string[] data = Regex.Split(strSPCData, "\r\n");
            int intCtr = 0;
            foreach (IWebElement txtbox in txtBoxes)
            {
                if (txtbox.GetAttribute("className") != null)
                {
                    if (txtbox.GetAttribute("className").Equals("vcs_de_textbox") && intCtr < data.Length)
                    {
                        txtbox.SendKeys(data[intCtr]);
                        intCtr++;
                    }
                }
            }

            foreach (IWebElement button in txtBoxes)
            {
                if (button.GetAttribute("className") != null)
                {
                    if (button.GetAttribute("className").Equals("vcs_de_saveButton"))
                    {
                        button.Click();
                    }
                }
            }
        }

I checked your code and looks like you are trying to automate IE browser in your code.

You cannot run this same code for the Edge browser.

I suggest you try to use Microsoft Web driver to automate MS Edge browser using c# code.

Here is a code example:

using OpenQA.Selenium;
using OpenQA.Selenium.Edge;
using System;

namespace EdgeDriverTests
{
    public class Program
    {
        /*
        * This assumes you have added MicrosoftWebDriver.exe to your System Path.
        * For help on adding an exe to your System Path, please see:
        * https://msdn.microsoft.com/en-us/library/office/ee537574(v=office.14).aspx
        */
        static void Main(string[] args)
        {
            /* You can find the latest version of Microsoft WebDriver here:
            * https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
            */
            var driver = new EdgeDriver();

            // Navigate to Bing
            driver.Url = "https://www.bing.com/";

            // Find the search box and query for webdriver
            var element = driver.FindElementById("sb_form_q");

            element.SendKeys("webdriver");
            element.SendKeys(Keys.Enter);

            Console.ReadLine();
            driver.Quit();
        }
    }
}
