Hi,
I want to open cmd and send "systeminfo" to it in order to get some system information,
but this code doesn't work :

C#

private void Form1_Load(object sender, EventArgs e)
        {
            System.Diagnostics.Process p = new System.Diagnostics.Process();
            p.StartInfo.FileName = "cmd";
            p.StartInfo.Arguments = "systeminfo";
            p.Start();
        }

what should I do?
Thanks.

For the example you provided, just set the FileName property to systeminfo.exe. You should also research the Process class a bit more. You probably need other properties to be set before calling Process.Start().

Exactly, my 5.

All your code does is launch the command. It doesn't log the information returned anywhere and your code doesn't read StdOut of the process you launched.

On top of that, all of the information you get from SystemInfo can be had with a proper application of WMI queries. You don't need to read and parse any external command at all.

Solution 1

Instead of starting a new cmd, try simply starting the msinfo32.exe which will launch the System Information window. And if you need command line arguments, have a look at this document: http://support.microsoft.com/kb/300887[^]

This is correct, my 5. Systeminfo.exe will also do it.

thank's but my exact problem is how to execute a command in cmd by using c#, system info was an example.

Wendelius 5-Apr-11 16:21pm

Ok, sorry about the misunderstanding. So if you want to use CMD to run something, perhaps you're looking for this kind of example:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo();
psi.FileName = "cmd";
psi.Arguments = "/K \"DIR C:\"";
process.StartInfo = psi;
process.Start();
I used /K switch so that the window will remain open in order to see the behaviour.

It works , thanks
do you know how can I execute more than 1 command in CMD?
for example :
first it change it's direction with "cd d:\"
and then some another commands.

Wendelius 6-Apr-11 15:27pm

Glad it helped. The easiest way is to create a batch file where you have all the relevant commands and you execute that batch file in the CMD. SOmething like /K C:\TEMP\MyBatch.bat
