How to use more DOS commands in C#

I have about 7 commands in DOS and I want to run them in my C# program. Can I do:

System.Diagnostics.Process.Start("cmd.exe", "my more commands here");

? EDIT: I'm making small app what will run g++. Is this now correct?:

 System.Diagnostics.Process.Start("cmd.exe", "/k cd C:\\Alps\\compiler\\ /k g++ C:\\Alps\\" + project_name + "\\Debug\\Main.cpp");

Command for compiling:

g++ -c C:开发者_如何学编程\Alps\here_is_projectname\Debug\Main.cpp -o main.o

cmd.exe /k <command>
cmd.exe /c <command>

Are both valid.

• /k will execute the command and leave you with an empty prompt (probably less desirable in your application if you just want to execute for feedback.)
• /c will execute the command and close the window when it has completed.

If you're looking to execute a command from a specific directory, you can do:

System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo = new System.Diagnostics.ProcessStartInfo("cmd.exe");
p.StartInfo.Arguments = String.Format(@"/c g++ ""C:\Alps\{0}\Debug\Main.cpp""", project_name);
p.StartInfo.WorkingDirectory = @"C:\Alps\compiler";
p.StartInfo.CreateNoWindow = true;
p.StartInfo.ErrorDialog = false;
p.Start();

Yes, you can pass in the command line using the "/C" switch:

System.Diagnostics.Process.Start("cmd.exe", "/C dir");

You can also do like the following....

Process.Start(new ProcessStartInfo()
{
 Arguments = "args",
 WorkingDirectory = "C:\SomePath",
 UseShellExecute= true,
 FileName = ".exe"
});

There are also options on the processstartinfo to redirect input and output if you need to

For example..

Process.Start(new ProcessStartInfo()
{
 Arguments = "C:\\Alps\\" + project_name + "\\Debug\\Main.cpp",
 WorkingDirectory = "C:\\Apls\\",
 UseShellExecute= true,
 FileName = "g++.exe"
});

---

You can launch cmd.exe redirect the stdin and feet that stream with your commands.

 process.Start(...);


                    process.StandardInput.WriteLine("Dir xxxxx");
                    process.StandardInput.WriteLine("Dir yyyyy");
                    process.StandardInput.WriteLine("Dir zzzzzz");
                    process.StandardInput.WriteLine("other command(s)");

Of course you should remeber to set your process star info to say you want redirect input:

 ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe);
        processStartInfo.CreateNoWindow = true;

        processStartInfo.ErrorDialog = false;

        processStartInfo.RedirectStandardInput = true;
