redirection operator compatible console application

[muquaddim]

Hi,
I have a program prog.exe. which takes IP as input its owner
information as output.
if input.txt contains,
xx.xx.xx.xx
yy.yy.yy.yy
zz.zz.zz.zz

now see how it works.

c:\> prog.exe xx.xx.xx.xx yy.yy.yy.yy > output.txt

it generates output.txt with contact info for each ip.

if I don't pass any command line argument it takes input from stdin.
c:\> prog.exe
xx.xx.xx.xx // my input
(e-mail address removed) // contact info
yy.yy.yy.yy // my input
(e-mail address removed) // contact info

to break the program I have to press Ctrl+C

Now if I use input redirection operator
c:\> prog.exe < input.txt
(e-mail address removed)
(e-mail address removed)
(e-mail address removed)

In this point my program waits for standard input too.
I want my program should process all the input and output the data
then exit. no wait.

For this problem I can not run the following command,

C:\> prog.exe < input.txt > output.txt

I never know whether the program has ended.

The simple Code can be found in http://nopaste.info/31b391011b.html

Please give me a solution.

Thanks in Advance.

The way your program is built, it should exit out of the loop when it
hits the end of the data.

The correct way to end the program is to hit Ctrl+Z when you're giving
it text from the console.

When you give it text from a file, or from a different program, it
should terminate by its own.

However, you haven't shown what "startProcess" does, so there could be
other things that holds your program up.

Try the following simple program and see if it behaves as you expect:

using System;

namespace ConsoleApplication1
{
class Program
{
static void Main(String[] args)
{
while (true)
{
String s = Console.In.ReadLine();
if (s == null)
break;
Console.Out.WriteLine(s);
}
}
}
}

its solved

while((ip=Console.ReadLine())!=null){

}

so easy
