Can Console Clear be used to only clear a line instead of whole console

Question

While working on a question answer program for school  it occurred to me that I can use Console Clear   to wipe out everything on the screen  I wonder if I can use Console Readline valueOne   then output only the answer without the question  If I only asked one question  the Console Clear works   I have several questions with values not references  to erase if possible  I want to leave out the questions and only display several answers  I think if I store the answers  I could use Console Clear   then just Console WriteLine   with three variables  I could do something like this   Console WriteLine  Value 1 is   0 c      Value 2 is   1 c      Value 3 is   2 c   valueOne  valueTwo  valueThree     The problem is easier with references because the values are stored and retrieved  If I simply use methods to pass by value and output the value  main   will not have a reference to those values to clear and output again  That s why I wonder if I can just ask a question  then erase the line and output only the answer  or answers    I am just trying to understand the possibilities and not trying to setup a program  I like to know the abilities of outputting a value from reference and by value without extra output questions

Description  You can use the Console SetCursorPosition function to go to a specific line number  Than you can use this function to clear the line  public static void ClearCurrentConsoleLine         int currentLineCursor   Console CursorTop      Console SetCursorPosition 0  Console CursorTop       Console Write new string      Console WindowWidth         Console SetCursorPosition 0  currentLineCursor       Sample  Console WriteLine  Test    Console SetCursorPosition 0  Console CursorTop - 1   ClearCurrentConsoleLine      More Information   Console SetCursorPosition Method

We could simply write the following method  public static void ClearLine         Console SetCursorPosition 0  Console CursorTop - 1       Console Write new string      Console WindowWidth        Console SetCursorPosition 0  Console CursorTop - 1       and then call it when needed like this  Console WriteLine  Test    ClearLine      It works fine for me

ClearCurrentConsoleLine    ClearLine  and the rest of the above functions should use Console BufferWidth instead of Console WindowWidth  you can see why when you try to make the window smaller   The window size of the console currently depends of its buffer and cannot be wider than it  Example  thanks goes to Dan Cornilescu    public static void ClearLastLine         Console SetCursorPosition 0  Console CursorTop - 1       Console Write new string      Console BufferWidth        Console SetCursorPosition 0  Console CursorTop - 1

To clear from the current position to the end of the current line  do this       public static void ClearToEndOfCurrentLine                 int currentLeft   Console CursorLeft          int currentTop   Console CursorTop          Console Write new String      Console WindowWidth - currentLeft            Console SetCursorPosition currentLeft  currentTop

This worked for me   static void ClearLine        Console SetCursorPosition 0  Console CursorTop       Console Write new string      Console WindowWidth         Console SetCursorPosition 0  Console CursorTop - 1

I think I found why there are a few varying answers for this question  When the window has been resized such that it has a horizontal scroll bar  because the buffer is larger than the window  Console CursorTop seems to return the wrong line  The following code works for me  regardless of window size or cursor position   public static void ClearLine         Console SetCursorPosition 0  Console CursorTop       Console Write new string      Console WindowWidth        Console SetCursorPosition 0  Console CursorTop -  Console WindowWidth  gt   Console BufferWidth   1   0        Without the  Console WindowWidth    Console BufferWidth   1   0   the code may either move the cursor up or down  depending on which version you use from this page  and the state of the window

My preferred method is to use PadRight  Instead of clearing the line first  this clears the remainder of the line after the new text is displayed  saving a step   Console CursorTop   0  Console CursorLeft   0  Console Write  Whatever     PadRight Console BufferWidth

A simpler and imho better solution is   Console Write   r    new string      Console WindowWidth      r      It uses the carriage return to go to the beginning of the line  then prints as many spaces as the console is width and returns to the beginning of the line again  so you can print your own test afterwards
