Problem with symbol using CMD.exe

Hi everyone,

I must to execute, using cmd.exe, a command.

The command is : netsh interface ip set address "name" static "ip" "subnet" "gateway"

This is my code:

C#

string IP = txtIP.Text;
           string Subnet = txtSubnet.Text;
           string Gateway = txtGateway.Text;
           string Nome_Maschera = '"' + Maschera_di_Rete.Nome_Maschera.ToString() +'"' ;

           DialogResult risultato = MessageBox.Show("Sicuro di voler attribuire i seguenti indirizzi?", "AVVISO", MessageBoxButtons.OKCancel);
           switch (risultato)
           {
               case DialogResult.OK:
                   {

                       string comando;
                       comando = "netsh interface ip set address " + Nome_Maschera.ToString() + " static " + IP.ToString() + " " + Subnet.ToString() + " " + Gateway.ToString();
                       ProcessStartInfo procStartInfo = new ProcessStartInfo();
                       procStartInfo.RedirectStandardOutput = true;
                       procStartInfo.UseShellExecute = false;
                       procStartInfo.CreateNoWindow = true;
                       procStartInfo.FileName = "runas.exe";
                       procStartInfo.Arguments = "/user:Administrator cmd /K " + comando;

                       Process proc = new Process();
                       proc.StartInfo = procStartInfo;
                       proc.Start();

                       string result = proc.StandardOutput.ReadToEnd();
                       break;
                   }
               case DialogResult.Cancel:
                   {
                       break;
                   }
           }

The output isn't correct, because Visual Studio put automatically the symbol "\" before and after the network's name.
Like this: netsh interface ip set address \"Connessione alla rete locale (LAN) \" static 192.168.50.180 255.255.255.0 192.168.50.254

How can I remove the symbol \?

Are you sure that you don't missinterpret what you see in Debugger? Why should VS add "\"?

nicola_melc 17-Oct-14 5:36am

I don't now why VS add the symbol "\" before and after the network's name.
But, the command doesn't work. I don't have error at the end, but I have the addresses automatically assigned. The command must to assign it static

What is the type of "Maschera_di_Rete"?
Why you don't remove the "\" by yourself (only for test to check wheter this is really your problem)?

nicola_melc 17-Oct-14 6:05am

I have two forms:
In the first I use the command: netsh interface ip show config

I put in a listbox every network's name that I found. With doubleclickevent on the selected item I open the second form where I put manually IP, Subnet and Gateway.
I press a button (Confirm).

In the code I assign at the variable Nome_Maschera the Network's name from the first form. In my case, Maschera_di_Rete is the class and Nome_Maschera is the variable

And BTW it makes it easier if you answer directly to the comment ;)

It doesn't work.
I already tried with this: procStartInfo.Arguments = ("/user:Administrator cmd /K " + comando.Replace(@"\",""));

The output is:
netsh interface ip set address Connessione alla rete locale (LAN) static ip subnet gateway

MukeshSagar 17-Oct-14 5:55am

I think first try this command from command line prompt whether it is working fine or nor

nicola_melc 17-Oct-14 6:00am

I' ve tried from command line this:
netsh interface ip set address "Network's Name" static ip subnet gateway
It works correctly.

Then Launch netsh directly without the use of cmd.exe

How can I run netsh as administrator in C#?

[no name] 17-Oct-14 8:28am

What I know, only by executing it in a elevated process :(

nicola_melc 20-Oct-14 3:42am

I've solved my problem.
I tried to launch directly netsh without using cmd.exe, but VS asked to me to execute the command with elevated privileges, so I added a file .manifest to run as administrator my application.
So, the command "netsh" works.

Thanks so much for the help, bye.
