How to pass an argument to cmd.exe ?

Question

static void Main(string[] args)
        {

              Process p = new Process();
              ProcessStartInfo startInfo = new ProcessStartInfo();
              startInfo.FileName =@"C:\systemprocess\cmd.exe";
              //I want to pass an argument to my cmd.exe

              p.StartInfo = startInfo;
              p.Start();
          }

This will open the cmd.exe . But I want to Send something programmatic.

Actually When I open Cmd I will give

1) d:
2) cd folder1
3) Force it 10.10.26.0 -a

 I will type this in exe.Now I want to this in Programmatic.How to do this?
