I build a console application which will prompt for User Name and Password

I have a web application on button click I need to call the console exe to popup the username and password once the user key in the user name and password i need to get the values to pass to my web application

      string filePath = @"D:\\ConsoleApplication\\ConsoleApplication\\ConsoleApplication\\bin\Debug\\ConsoleApplication.exe";
             ProcessStartInfo info = new ProcessStartInfo(filePath, "");
             Process p = Process.Start(info);
            p.StartInfo.UseShellExecute = false;           //don't use the shell to execute the cmd file                                           
            p.StartInfo.RedirectStandardOutput = true;     //redirect the standard output
            p.StartInfo.RedirectStandardError = true;      //redirect standard errors
            p.StartInfo.CreateNoWindow = true;            //don't create a new window
            p.Start();                                   //start the program
            StreamReader sr = p.StandardOutput;         //read the programs output
            string output = sr.ReadToEnd();              //put output into list box
            p.Close();
            p.WaitForExit();

Console Application Code :

  public class Program
    {
        static void Main()
        {
            System.Console.WriteLine("Please enter User Name");
            var userName = Console.ReadLine();
           System.Console.WriteLine("Please enter Password");
           var password = Console.ReadLine();          
        }
    }

I tried with above code to get the values from standardoutput but the values are empty

Below implementation is working for me.

Write to text file and read the values in the web application

Console Code :

 public class Program
    {
        static void Main()
        {
            System.Console.WriteLine("Please enter User Name");
            string userName = Console.ReadLine();
            System.Console.WriteLine("Please enter Password");
            string password = Console.ReadLine();
            var sw = new StreamWriter(Environment.CurrentDirectory + "\\TA.txt");
            sw.Write(userName + "," + password );
            sw.Flush();
            sw.Close();
        }
    }

web Application:

 // Run the console application to key-in the User Name and Password
            string userName = string.Empty; string password = string.Empty;
            TestLog.BeginSection("Step 1: Create New WebAdmin User");
            const string filePath = @"D:\\ConsoleApplication\\ConsoleApplication\\ConsoleApplication\\bin\Debug\\ConsoleApplication.exe";
            var info = new ProcessStartInfo(filePath, "");
            var p = Process.Start(info);
            p.StartInfo.UseShellExecute = false;           //don't use the shell to execute the cmd file                                           
            p.StartInfo.RedirectStandardOutput = true;     //redirect the standard output
            p.StartInfo.RedirectStandardError = true;      //redirect standard errors
            p.StartInfo.CreateNoWindow = true;            //don't create a new window
            p.Start();                                   //start the program
            StreamReader sr = p.StandardOutput;         //read the programs output
            string output = sr.ReadToEnd();             //put output into list box  
            p.Close();
            Thread.Sleep(40000);

            // Read the file as one string.
            var userNamePassword = System.IO.File.ReadAllText(Environment.CurrentDirectory + @"\\TA.txt");
            var strarray = userNamePassword.Split(',');
            if (strarray.Length > 1)
            {
                userName = strarray[0];
                password = strarray[1];
            }
            // Delete the file
            if (File.Exists(Environment.CurrentDirectory + @"\TA.txt"))
            {
                File.Delete(Environment.CurrentDirectory + @"\TA.txt");
            }

You will have the values in username and password parameters.

Happy coding..:)
