Hello.

I want to know is there any way we can get an ip address range of an network or DNS suffix name.

Example, when i type ipconfig in commandprompt, i will get information as below

XML

<pre lang="css">
Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . : COMPANY-NAME-MY
   Link-local IPv6 Address . . . . . : fe80::3134:1e1b:f018:7280%22
   IPv4 Address. . . . . . . . . . . : 192.168.2.140
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.2.1

</pre>

C#

try
          {

              System.Diagnostics.ProcessStartInfo runcmd =
              new System.Diagnostics.ProcessStartInfo("cmd", "/c " + "ipconfig");


              runcmd.RedirectStandardOutput = true;
              runcmd.UseShellExecute = false;
              runcmd.CreateNoWindow = true;
              System.Diagnostics.Process proc = new System.Diagnostics.Process();
              proc.StartInfo = runcmd;
              proc.Start();
              string result = proc.StandardOutput.ReadToEnd();
              textBox1.Text = result;

          }
          catch (Exception objException)
          {

Hi Mukund,

i am using windows 7 ultimate edition and vs2010 and using as an administrator so i never had this error.
i am sorry for the error but still not sure why the error was occured ?

i will see if something i can do.
meanwhile... please try to login as administrator and run the code again.
