Figure 1: the bottom portion is to scroll, while the top portion is to stay put.
So I’m writing a CLI .NET Core application.
The top portion of the image is to stay put whereas the bottom portion is to scroll under the top portion.
If there was a more direct access to the console, it would be rather easy. But as we are in C#, no such (cross-platform) access exists that I am aware of.
So, how would I achieve the desired goal here, without platform-locking?
Answer
You can try this if it might give you an idea. Based on this post C# Console : How to make the console stop scrolling automatically?.
static readonly int maxLine = 10;
static int currentLine = 0;
static void Main(string[] args)
{
setHeader();
while (true)
{
writeLine("Please type and enter:");
string value = Console.ReadLine();
writeLine($"Your input is: {value}");
writeLine($"Current Line: {currentLine}");
if (currentLine > maxLine)
{
resetCursorPosition();
writeLine($"Your input is: {value}");
writeLine($"Current Line: {currentLine}");
}
}
}
private static void writeLine(string value)
{
Console.WriteLine(value);
currentLine = currentLine + 1;
}
private static void resetCursorPosition()
{
Console.Clear();
Console.SetCursorPosition(0, 0);
currentLine = 0;
setHeader();
}
private static void setHeader()
{
writeLine("----------------------------------------------");
writeLine("---------------MY CUSTOM HEADER---------------");
writeLine("----------------------------------------------");
}
Output:
