using System.Diagnostics; 
 
using System.IO; 
 
//Gets the machine names that are connected on LAN 
 
Process netUtility = new Process(); 
 
netUtility.StartInfo.FileName = "net.exe"; 
 
netUtility.StartInfo.CreateNoWindow = true; 
 
netUtility.StartInfo.Arguments = "view"; 
 
netUtility.StartInfo.RedirectStandardOutput = true; 
 
netUtility.StartInfo.UseShellExecute = false; 
 
netUtility.StartInfo.RedirectStandardError = true; 
 
netUtility.Start(); 
 
  
 
StreamReader streamReader = new StreamReader(netUtility.StandardOutput.BaseStream, netUtility.StandardOutput.CurrentEncoding); 
 
  
 
string line = ""; 
 
while ((line = streamReader.ReadLine()) != null) 
 
{ 
 
      if (line.StartsWith("\\")) 
 
      { 
 
           listBox1.Items.Add(line.Substring(2).Substring(0, line.Substring(2).IndexOf(" ")).ToUpper()); 
 
      } 
 
} 
 
streamReader.Close(); 
netUtility.WaitForExit(1000);

Try this code-

Using System.net you can get this ,
 
and using the following

    //To get the local IP address
string sHostName = Dns.GetHostName ();
IPHostEntry ipE = Dns.GetHostByName (sHostName);
IPAddress [] IpA = ipE.AddressList;
for (int i = 0; i < IpA.Length; i++)
{
    Console.WriteLine ("IP Address {0}: {1} ", i, IpA[i].ToString ());
}

Murtaza ,

You need to get the all IP Addresses of NetWork Computers

Do like this
if (ip.AddressFamily.ToString() == "InterNetwork")
