c# - 将控制台分成两部分以获得两个输出

Question

我正在创建一个控制台应用程序，我希望其中有两个输出和一个输入。原因是一个输出始终可见。

This is the first output
Text flows upwards just like a regular console application, however...

---------
This is a second output
This is placed at the bottom of the console // also input goes here.

我想这样调用它

 Console.Out.Writeline("This is the first output");
 Console.Out.Writeline("Text flows upwards just like a regular console application, however...");
 MyTextWriter.WriteLine("This is a second output");
 MyTextWriter.WriteLine("This is placed at the bottom of the console");

但是我该如何将控制台分成两部分呢？有可能吗？

如果我的理解正确，您可以使用 Console.SetCursorPosition 在您想要的位置绘制文本。这是一个粗略的示例，它将控制台分成两个区域，添加的文本向上流动。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static List<string> area1 = new List<string>();
        static List<string> area2 = new List<string>();
        static int areaHeights = 0;

        static void Main(string[] args)
        {
            // Number of rows for each area
            areaHeights = (Console.WindowHeight - 2) / 2;

            drawScreen();

            int i = 0;
            while (true)
            {
                i++;

                // jumb between areas
                if (i % 2 == 0)
                    AddLineToBuffer(ref area1, Console.ReadLine());
                else
                    AddLineToBuffer(ref area2, Console.ReadLine());

                drawScreen();
            }
        }

        private static void AddLineToBuffer(ref List<string> areaBuffer, string line)
        {
            areaBuffer.Insert(0, line);

            if (areaBuffer.Count == areaHeights)
            {
                areaBuffer.RemoveAt(areaHeights - 1);
            }
        }


        private static void drawScreen()
        {
            Console.Clear();

            // Draw the area divider
            for (int i = 0; i < Console.BufferWidth; i++)
            {
                Console.SetCursorPosition(i, areaHeights);
                Console.Write('=');
            }

            int currentLine = areaHeights - 1;

            for (int i = 0; i < area1.Count; i++)
            {
                Console.SetCursorPosition(0, currentLine - (i + 1));
                Console.WriteLine(area1[i]);

            }

            currentLine = (areaHeights * 2);
            for(int i = 0; i < area2.Count; i++)
            {
                Console.SetCursorPosition(0, currentLine - (i + 1));
                Console.WriteLine(area2[i]);
            }

            Console.SetCursorPosition(0, Console.WindowHeight - 1);
            Console.Write("> ");

        }

    }
}

我假设您不仅要用用户输入来填充每个区域？如果是这样，您需要在单独的线程中设置控制台的绘图，并让该线程在需要时更新屏幕。
