You could use the Process.Start method:

class Program
{
    static void Main()
    {
        var psi = new ProcessStartInfo
        {
            FileName = @"c:\work\test.exe",
            Arguments = @"param1 param2",
            UseShellExecute = false,
            RedirectStandardOutput = true,
        };
        var process = Process.Start(psi);
        if (process.WaitForExit((int)TimeSpan.FromSeconds(10).TotalMilliseconds))
        {
            var result = process.StandardOutput.ReadToEnd();
            Console.WriteLine(result);
        }
    }
}
