Returning value to batch file from c#

Question

I want to call a c# program from a batch file and then use the output generated from the c# program as  avarable that can be passed on to another c# program from same batch file.

 

dummy c# code-

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication3

{

class Program

{

static void Main(string[] args)

{

System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo(@"C:\Users\u316383\Desktop\gre\test.bat");

psi.Arguments = "Evandro 09/08/1977";

psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;

psi.UseShellExecute = false;

System.Diagnostics.Process p = System.Diagnostics.Process.Start(psi);

p.Start();

p.Kill();

System.Console.Read();

}

}

}

 

and my bacth file is :

echo off

echo Name: %1

echo Birth: %2

set v= %1

echo data : v

---

the problem is  though name is dispalyed by taking arguement (%1),but value of v is not getting set as %1.
