Running a Command

[stevenk140]

I want to run a command like &quot;dir&quot; or &quot;del <filename&quot;. How do you do this in C#? In C\C++ you can do a System(cmd); What is the C# equivalent?

use this but it will not work on any internal commands

System.Diagnostics.Process.Start(@&quot;c:\yourfilename.exe&quot;

You put everything in a .bat file and execute it or you can generate on the fly a temporary .bat file with the commands you want to execute and after that delete this .bat file .
Example:
C:\\tmp.bat contains;
echo Start > t1.lis
dir >> t1.lis
Now execute it with these statements:

System.Diagnostics.Process P = null;
try {
	P = new System.Diagnostics.Process();
	string WorkingDirectory = "C:\\docs";
	//P.StartInfo.RedirectStandardOutput = true;
	P.StartInfo.CreateNoWindow = true;
	P.StartInfo.WorkingDirectory = WorkingDirectory;
	P.StartInfo.FileName =  "C:\\tmp.bat";
	//P.StartInfo.Arguments = "";				//P.EnableRaisingEvents = true;
	P.StartInfo.UseShellExecute = false;
	P.Start();
}
catch(Exception er)
{
	string sMsg = "Error in starting process " + er.GetType() + er.Message;
}

The C:\\tmp.bat is executed and the t1.lis file will be created in the workingdirectory e.g. C:\Docs\t1.lis
You also can capture the output of the tmp.bat by RedirectStandardOutput to true and use P.StandardOutput.ReadToEnd();

Stevenk140 -

I'm assuming you used &quot;dir&quot; and &quot;del&quot; as examples? Because that functionality already exists in the .NET framework. Take a look in the System.IO namespace, at the DirectoryInfo class and the File class.
