C# Winform Code

public partial class Form1 : Form
    {
        private SHDocVw.InternetExplorer TargetIE = null;
        string url;
        public Form1()
        {
        this.button1 = new System.Windows.Forms.Button();
        this.textBox1 = new System.Windows.Forms.TextBox();
        this.textBox2 = new System.Windows.Forms.TextBox();
        this.textBox3 = new System.Windows.Forms.TextBox();
        this.textBox4 = new System.Windows.Forms.TextBox();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            GetTheIEObjectFromSystem("Q_26773800");
            SendTextToActiveElementWithSubmitOptionSet(false);
        }
        private void GetTheIEObjectFromSystem(string inurl = ".")
        {
            SHDocVw.ShellWindows SWs = new SHDocVw.ShellWindows();
            foreach (SHDocVw.InternetExplorer internetExplorer in SWs)
            {
                url = internetExplorer.LocationURL;
                TargetIE = internetExplorer;
                return;
            }

        }
        private void SendTextToActiveElementWithSubmitOptionSet(bool btnSubmit)
        {
            mshtml.IHTMLDocument2 document = null;
            document = TargetIE.Document as mshtml.IHTMLDocument2;
            if (!document.activeElement.isTextEdit)
            {
                MessageBox.Show("Active element is not a text-input system");
            }
            else
            {
                HTMLInputElement HTMLI;
                //HTMLI = document.activeElement as HTMLInputElement;

                 HTMLI = document.activeElement as HTMLInputElement;
                 var tag = HTMLI.document as mshtml.HTMLDocumentClass;
                 mshtml.IHTMLElementCollection a = tag.getElementsByTagName("input");
                 for (int i = 0; i< a.length; i++) // a.length = 4
                 {

                 }
                HTMLI.value = textBox1.Text;

            }
        }
    }
}

Using this code only the first winform textbox value is passess to HTML Textbox but i want to transfer the values for other textxbox from winform textbox to html textbox.

using the for loop I get an Length = 4 but I dont know how to use this loop to transfer the data from winform to html?
