操作方法:在控制台应用程序中绘制表格的最佳方法 (C#) [英] How To: Best way to draw table in console app (C#)

问题描述

我有一个有趣的问题.想象一下，我有很多数据以非常快的间隔发生变化.我想在控制台应用程序中将该数据显示为表格.f.ex:

I have an interesting question. Imagine I have a lot of data changing in very fast intervals. I want to display that data as a table in console app. f.ex:

-------------------------------------------------------------------------
|    Column 1     |    Column 2     |    Column 3     |    Column 4     |
-------------------------------------------------------------------------
|                 |                 |                 |                 |
|                 |                 |                 |                 |
|                 |                 |                 |                 |
-------------------------------------------------------------------------

如何保持快速以及如何固定列宽?我知道如何在 java 中做到这一点，但我不知道它是如何在 C# 中完成的.

How to keep things fast and how to fix column widths ? I know how to do that in java, but I don't how it's done in C#.

推荐答案

你可以这样做:

static int tableWidth = 73;

static void Main(string[] args)
{
    Console.Clear();
    PrintLine();
    PrintRow("Column 1", "Column 2", "Column 3", "Column 4");
    PrintLine();
    PrintRow("", "", "", "");
    PrintRow("", "", "", "");
    PrintLine();
    Console.ReadLine();
}

static void PrintLine()
{
    Console.WriteLine(new string('-', tableWidth));
}

static void PrintRow(params string[] columns)
{
    int width = (tableWidth - columns.Length) / columns.Length;
    string row = "|";

    foreach (string column in columns)
    {
        row += AlignCentre(column, width) + "|";
    }

    Console.WriteLine(row);
}

static string AlignCentre(string text, int width)
{
    text = text.Length > width ? text.Substring(0, width - 3) + "..." : text;

    if (string.IsNullOrEmpty(text))
    {
        return new string(' ', width);
    }
    else
    {
        return text.PadRight(width - (width - text.Length) / 2).PadLeft(width);
    }
}
