Batch file commands in c#

Question

I have a batch file I use
CD /D %~dp0
IF /I "%~1" NEQ "" CD /D %1
FOR /F "tokens=* delims=" %%A IN ('DIR *.MSI /B /S') DO (
cscript.exe GetMSICodes.vbs "%%A" //Nologo >> Codes.txt
)
Is there an way to re-create this in C#?

The following should be on the right lines but may need some more work to get it to produce the same results as the batch file does.
Don't expect it to run too quickly as (of necessity) it creates a new process for each file found.
using System; using System.IO; using System.Diagnostics; using System.Linq;
class Program {    static void Main(string[] args)    {         if (args.Length == 0)       {         Console.WriteLine("Directory path should be passed as a command line argument");         return;       }
string dirPath = args[0];           if (!Directory.Exists(dirPath))       {         Console.WriteLine("{0} is not a valid directory path", dirPath);         return;       }
DirectoryInfo di = new DirectoryInfo(dirPath);       FileInfo[] fia = di.GetFiles("*.msi");       fia = (from fi in fia orderby fi.Length select fi).ToArray(); // sort files by length       StreamWriter sw = new StreamWriter("codes.txt"); // overwrite if already exists
foreach(FileInfo fi in fia)       {          using (Process p = new Process())          {             p.StartInfo.UseShellExecute = false;             p.StartInfo.RedirectStandardOutput = true;             p.StartInfo.FileName = "cscript.exe";             p.StartInfo.Arguments = "GetMSICodes.vbs " + fi.FullName;             p.Start();             string output = p.StandardOutput.ReadToEnd();                       p.WaitForExit();             sw.WriteLine(output);          }       }
sw.Close();     }  }
