Pinging using ASP.NET 2.0 and C# .NET

This tutorial will show you how to ping a hostname/ip using the .NET System.Net class, ASP.NET 2.0 and C#.NET

The .NET Framework offers a number of types that makes accessing resources on the network easy to use.

To perform a simple ping, we will need to use the System.Net, System.Net.Network.Information, System.Text namespaces.

using System.Net; using System.Net.NetworkInformation; using System.Text;

If you're looking for a really good web host, try Server Intellect - we found the setup procedure and control panel, very easy to adapt to and their IT team is awesome!

We'll put our code in the btnSubmit_Click() event.

When the btnSubmit_Click() event fires it creates a new Ping object. We can then execute the Send method of this object to send a ping to the host specified in our text box. Executing this method also returns a PingReply object which we can use to gather information such as the Address, Roundtrip Time, TTL, and Buffer Size.

protected void btnSubmit_Click(object sender, EventArgs e) { try { lblStatus.Text = null; Ping ping = new Ping(); PingReply pingreply = ping.Send(txtHost.Text); txtPing.Text += "Address: " + pingreply.Address + "\r"; txtPing.Text += "Roundtrip Time: " + pingreply.RoundtripTime + "\r"; txtPing.Text += "TTL (Time To Live): " + pingreply.Options.Ttl + "\r"; txtPing.Text += "Buffer Size: " + pingreply.Buffer.Length.ToString() + "\r"; } catch (Exception err) { lblStatus.Text = err.Message; } }

Yes, it is possible to find a good web host. Sometimes it takes a while. After trying several, we went with Server Intellect and have been very happy. They are the most professional, customer service friendly and technically knowledgeable host we've found so far.

The front end .aspx page looks something like this:

<table width="600" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#cccccc"> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1">Hostname/IP:</td> <td align="center" bgcolor="#FFFFFF"> <asp:TextBox ID="txtHost" runat="server"></asp:TextBox> &nbsp;&nbsp; <asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" /></td> </tr> <tr> <td width="100" align="right" bgcolor="#eeeeee" class="header1">Ping Results:</td> <td align="center" bgcolor="#FFFFFF"> <asp:TextBox ID="txtPing" runat="server" Height="66px" TextMode="MultiLine" Width="226px"></asp:TextBox>&nbsp;<br /> <asp:label ID="lblStatus" runat="server"></asp:label></td> </tr> </table>
