How to write in current line of Console?

I am writing a console application and I need to know, how to write in current line with shift of lines. I try to explain this on the next example: Let It console lines with their numbers and contents along with cursor position.

  1. Hello!
  2. This is my command shell.
  3. Please write something: _

When I call my method for writing in console text "lalala", i want to see that:

  1. Hello!
  2. This is my command shell.
  3. lalala
  4. Please write something: _

If I use Console.WriteLine method I see the next:

  1. Hello!
  2. This is my command shell.
  3. Please write something: lalala
  4. _

Please, help me to realise this feature.

I realize that this is an old question, however I have been searching this stuff and here is how it can be coded:

Console.WriteLine("Hello!");
Console.WriteLine("This is my command shell.");
string text = "";
string toWrite = "Please write something: ";
while (text != "quit")
{
    Console.Write(toWrite);
    text = Console.ReadLine();
    Console.SetCursorPosition(0, Console.CursorTop - 1);
    Console.WriteLine(text.PadRight(text.Length + toWrite.Length));
}

The Console.SetCursorPosition puts the cursor back to the line that was written into, then overwrite what is written with the text and a padding equivalent to how many chars the text had.

try something like this

Console.Write("Hello\nThis is My Command Shell\nlalala\nPlease Enter Something:___");

if course that would end up having them all appear at the same time, but if your good with that this will work

Will look like this

Please find the code for the above scenario:

private static void ReadAndWriteToConsole()
    {
        var mystrings = new List<string>();

        mystrings.Add("Hello!");
        mystrings.Add("This is my command shell.");

        var input = WriteToConsole(mystrings);
        while (input.ToLower() != "exit")
        {
            mystrings.Add(input);
            Console.Clear();
            input = WriteToConsole(mystrings);
        }
    }

    private static string WriteToConsole(IEnumerable<string> variables )
    {
        foreach (var str in variables)
        {
            Console.WriteLine(str);
        }
        Console.Write("Please write something:");
        return Console.ReadLine();
    }

Hope that helps.

NOTE: If you want the number of each string then use a for loop instead of foreach and just print the variable used in the console.writeline.

Console.WriteLine("1.Hello!");
Console.WriteLine("2.This is my command shell.");
Console.WriteLine("3.lalala");
Console.Write("4.Please write something:");
Console.Read();

If I understand your question right I think you need to use

Console.Write("text");

This will write on the same line as the cursor is currently on.

Rather than:

Console.WriteLine("text");

This will create a new line in the console each time it is called.

Console.SetCursorPosition is the poison you are look for. More details on http://msdn.microsoft.com/en-us/library/system.console.setcursorposition.aspx

As you didn't provide any code i assume you're using Console.WriteLine("Please write something"); to print out text. Since this will add an \n to the text you want to print you should rather use Console.Write("Please write something") then do an Console.ReadLine(); to get the input and handle the \n by yourself.
