Answer 1

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);
        }
    }
}

Answer 2

You need to use the Process.Start method.

You supply it with the name of your process and any command line arguments and it will run the executable.

You can capture any output which you can then process in your C# application.
