Error due Console.ReadKey() when you start Process

Question

Sorry for my english.

I need from one application to run the console application, and read all that it outputs.

program 'App.exe':

static void Main(string[] args)
{
    foreach (string arg in args)
        Console.WriteLine(arg);

    Console.ReadKey(); // problem here
}

program that reads

static void Main(string[] args)
{
    Process process = new Process
    {
        StartInfo = new ProcessStartInfo
        {
            FileName = "App.exe",
            Arguments = "1 2 3 4 5",
            CreateNoWindow = true,
            UseShellExecute = false,
            RedirectStandardOutput = true
        }
    };

    process.Start();

    Console.WriteLine(process.StandardOutput.ReadToEnd());

    Console.ReadKey();
}

When you run crashes window. Is it possible to solve the problem without changing the application code 'App.exe'?

`ReadKey` reads from the standard input, have you tried redirecting that too? — DavidG, Feb 01 '17 at 14:30
`Console.ReadKey` reads the user input of keys pressed. I believe you're looking for `Console.Read()` — Ryan C, Feb 01 '17 at 14:30
No, you have to change the App code, since there lies your problem. — arias_JC, Feb 01 '17 at 14:32
Like @RyanCarlisle said, Console.ReadKey is waiting for user input, you have CreateNoWindow set to true, how can a user send input? — EpicKip, Feb 01 '17 at 14:34
To read up to the input block assign process.OutputDataReceived, call .Start() then .BeginOutputReadLine() — Alex K., Feb 01 '17 at 14:35
Use [Console.IsOutputRedirected](http://stackoverflow.com/a/3453272/17034) to know to not call ReadKey(). — Hans Passant, Feb 01 '17 at 16:02
