C#.如何将1D数组转换为2D数组

如果2D阵列仅作为帮助您打印的工具,则可以将其完全保留.

private static readonly char GraphBackgroundChar = '0';
private static readonly char GraphBarChar = '1';

void Main()
{
    int[] input = {4, 1, 6, 2};
    int graphHeight = input.Max(); // using System.Linq;

    for (int currentHeight = graphHeight - 1; currentHeight >= 0; currentHeight--)
    {
        OutputLayer(input, currentHeight);
    }
}

private static void OutputLayer(int[] input, int currentLevel)
{
    foreach (int value in input)
    {
        // We're currently printing the vertical level `currentLevel`.
        // Is this value's bar high enough to be shown on this height?
        char c = currentLevel >= value
            ? GraphBackgroundChar
            : GraphBarChar;
        Console.Write(c);
    }
    Console.WriteLine();
}

这基本上做的是它从输入中找到"最高条",然后从上到下遍历每个垂直级别,GraphBarChar每当图形条在input当前高度可见时打印.

一些样品:

input = {2,1,3};

001
101
111

input = {2,4,1,0,3};

01000
01001
11001
11101

如果您的目标平台支持终端仿真器中的框绘制字符,则可以使用以下字符表示一些非常有说服力的条形图:

private static readonly char GraphBackgroundChar = '?';
private static readonly char GraphBarChar = '?';

input = {2,1,3};

input = {2,4,1,0,3};
