Printing on the Spot in a Console
While installing something in Ubuntu from a terminal the installer printed a nice sequence of | / - \ in a single point on the console - a spinner. It is something trivial, but I didn’t know how to do it in C#. Now I do!
1using System;
2using System.Threading;
3
4namespace PrintOnTheSpot
5{
6 class Program
7 {
8 static void Main(string[] args)
9 {
10 int origRow = Console.CursorTop;
11 int origCol = Console.CursorLeft;
12 Console.CursorVisible = false;
13
14 char[] spinner = { '|', '/', '-', '\\'};
15 int loop = 0;
16
17 Console.WriteLine("Press any key to exit...");
18 while (!Console.KeyAvailable)
19 {
20 loop = loop > 3 ? 0 : loop;
21 Console.SetCursorPosition(origCol, origRow+1);
22 Console.Write(spinner[loop]);
23 loop++;
24 Thread.Sleep(200);
25 }
26 }
27 }
28}
There, a little program that was a lot of fun to make.
