Question

I’m using a button to get the IP address. I want to display that IP address in the text field.
This is my front end code:

<asp:TextBox ID="txtMachIP" runat="server" CssClass="Textbox1"></asp:TextBox>
 <asp:Button ID="BtnGetIP" runat="server" CssClass="btn1" 
                    onclick="BtnGetIP_Click" Text="Get My IP" />

This is my backend code for getting the ip:

 protected void BtnGetIP_Click(object sender, EventArgs e)
{
    string myHost = System.Net.Dns.GetHostName();
    System.Net.IPHostEntry myIPs = System.Net.Dns.GetHostEntry(myHost);
    foreach (System.Net.IPAddress myIP in myIPs.AddressList)
    {
        MessageBox.Show(myIP.ToString());

    }
}

Instead of the message box, I want my IP to be displayed in the text area.

Answer 1

Please give a name to your textbox like

<asp:TextBox ID="txtMachIP" NAME = "txtMachIPNAME" runat="server" CssClass="Textbox1"></asp:TextBox>

And in backend code

txtMachIPNAME.Text = myIP.ToString();
