Executing a unix style piping command?

Is there a way to execute the following command through C#?

.\binary.exe < input > output

I am trying to use System.Diagnostics.Process but I was wondering if there is a direct exec style command in C#. Any suggestions?

Not directly, but you can redirect output from a console stream (as you may have figured out, considering you're trying to use the Process class), as noted here on MSDN: http://msdn.microsoft.com/en-us/library/system.diagnostics.process.standardoutput.aspx

There is also an example here on SO: Redirect console output to textbox in separate program

Wrap that into your own class and it will basically become an "exec" style command.

Basically you need to redirect the standard input and output to your program and write them to the files you want

ProcessStartInfo info = new ProcessStartInfo("binary.exe");
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
Process p = Process.Start(info);

string Input;
// Read input file into Input here

StreamWriter w = new StreamWriter(p.StandardInput);
w.Write(Input);
w.Dispose();

StreamReader r = new StreamReader(p.StandardOutput);
string Output = r.ReadToEnd();
r.Dispose();

// Write Output to the output file

p.WaitForExit();
