.NET Tip: Execute Commands From C#

I usually run across the need to execute commands or run applications during the installation or configuration of an application. I've found this technique very useful in place of using batch files. You have a much more robust environment to work with and you don't have to worry about someone modifying your batch file. For this example, I'm just going to show you how execute a command that you would normally use in a Command Prompt. I normally include a function like the following in a static utility class so that it is accessible from anywhere in the application.

public static int ExecuteCommand(string Command, int Timeout)
{
   int ExitCode;
   ProcessStartInfo ProcessInfo;
   Process Process;

   ProcessInfo = new ProcessStartInfo("cmd.exe", "/C " + Command);
   ProcessInfo.CreateNoWindow = true; 
   ProcessInfo.UseShellExecute = false;
   Process = Process.Start(ProcessInfo);
   Process.WaitForExit(Timeout);
   ExitCode = Process.ExitCode;
   Process.Close();

   return ExitCode;
}

The key here is the ProcessStartInfo class that gives you access to a process to execute your command. Here, I am telling the process not to create a window and to use the operating system shell to start the process. There are many more options available for ProcessStartInfo, so make sure you check them out to see what you can take advantage of in your application. In this, case I'm telling the process to execute cmd.exe. The /C parameter tells cmd.exe to execute the following string and then terminate. Again, cmd.exe has many more options that you should explore. The code then starts the process and waits for it to wither complete or time out. Finally, the exit code of the process is returned from the function.

I hope that you can see how easy it is to execute commands from within your application and that this may spark additional ideas of how you can enhance your applications.

  • There has been growing buzz about DevOps. DevOps is a methodology that unites the often separate functions of software development (Dev) and production and operations (Ops) into a single, integrated, and continuous process. DevOps is about breaking down the barriers between Dev and Ops. It leverages people, processes, and technology to stimulate collaboration and innovation across the entire software development and release process. Dev and Ops should always be part of an integrated process, but that's not …
