how to separate/filter an output string and write the separated data into different text boxes?
So i have a button and two text boxes.
I want to click a button, it will execute nslookup then i want to :
-write the resolved hostname into one text box
-write the resolved ip adress into next text box
I have this so far
System.Diagnostics.Process p = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo();
psi.FileName = "nslookup.exe";
psi.Arguments = "google.com";
psi.RedirectStandardOutput = true;
psi.UseShellExecute = false;
psi.CreateNoWindow = false;
p.StartInfo = psi;
p.Start();
p.WaitForExit();
System.IO.StreamReader output = p.StandardOutput;
textbox1.Text = output.ReadToEnd().ToString();
So now it does the resolution and writes everything into one string.
How can i filter the output string and write specific parts of the string into separate boxes ?
Example output string will be : ( it is a single line string but i wrote it here in a table for easy understanding )
Server: EXAMPLE //this i dont need
Address: EXAMPLE //this i dont need
Name: google.com //i need this to be written to TextBox1
Address: 172.217.21.206 //i need this to be written to TextBox2
So that in the end :
Textbox.Text = "google.com"
Textbox2.Text = "172.217.21.206"
Later i want to ping the ip in textbox2 and make the text box change color if its reachable, and a button to rdp connect to that ip if its reachable, so i need it to not have any spaces and just be a string
I was thinking to write each word that is separated by a space into an array and then read the array and write things that match into the boxes with something like this :
string words = outputstring.Split(' ');
foreach (var word in words)
{
System.Console.WriteLine($"<{word}>");
}
But before i continue with it i wanted to ask if there is an easier and faster way to do it and im going in the wrong direction alltogether ? maybe there is a way to just return specific parameters out of the nslookup command ?
c# .net string nslookup

You can use Dns.GetHostEntry instead of manually calling external process:
IPHostEntry hostInfo = Dns.GetHostEntry("example.com");
textbox1.Text = hostInfo.HostName;
textbox2.Text = hostInfo.AddressList[yourIndex].ToString();
so what do i put in "yourIndex" ? if i put 1 or 2 it throws an index out of range exception

@JohnLinaer It depends what you want to get, for example forgoogle.com
it returns about10
addresses, what you want to show? What is your task?

Also you maybe will need to put this intry/catch
if it will be user input, cause it will throwSocketException
if host address will not be found.

well i have servers that are in my network, so a server host name would be example.domain.com, so then i wanna do an nslookup on "example" and it would return example.domain.com and that should be written into the text box. when i do nslookup using cmd it shows 2 names, first the domain one which usually is the first, and then the second which is the hostname that i am looking for, so basically i want it to return the hostname of the server + domain there is no user input, i just wanna make a server status checker, to see if the server is online + show the info like hostname and ip adress
