Question

我遇到了在C＃.NET4控制台应用程序中居中文本的问题。

这是我将文字居中的方法：

private static void centerText(String text)
{
    int winWidth = (Console.WindowWidth / 2);
    Console.WriteLine(String.Format("{0,"+winWidth+"}", text));
}

然而，我只是得到输出，因为它会正常输出。但是，如果我使用这一行：

Console.WriteLine(String.Format("{0,"+winWidth+"}", "text"));

“文本”按照应有的方式居中。

我用这两种方法调用centerText：

private static void drawStars()
{
    centerText("*********************************************");
}
private static void title(string location)
{
    drawStars();
    centerText("+++ Du er nu her: " + location + "! +++");
    drawStars();
}

Answer 1

请改为尝试：

private static void centerText(String text)
{
    Console.Write(new string(' ', (Console.WindowWidth - text.Length) / 2));
    Console.WriteLine(text);
}

初始代码的问题是您的文字在屏幕中心启动。你希望文本的中心在那里。

如果你想打印像这样的中心的整个段落，你会做更多的工作。

Answer 2

传入的文本可能有\r\n这样的空格，然后在调用写入之前将其删除，例如

string textClean = Regex.Replace(text, @"([\r\n])", string.Empty);

// Then center on text clean

Answer 3

我有自己的方法来调用控制台标题：

public static void Header(string title, string subtitle = "", ConsoleColor color = ConsoleColor.White)
{
    int windowWidth = 90 - 2;
    string titleContent = String.Format("║{0," + ((windowWidth / 2) + (title.Length / 2)) + "}{1," + (windowWidth - (windowWidth / 2) - (title.Length / 2) + 1) + "}", title, "║");
    string subtitleContent = String.Format("║{0," + ((windowWidth / 2) + (subtitle.Length / 2)) + "}{1," + (windowWidth - (windowWidth / 2) - (subtitle.Length / 2) + 1) + "}", subtitle, "║");

    Console.WriteLine("╔════════════════════════════════════════════════════════════════════════════════════════╗");
    Console.WriteLine(titleContent);
    if (!string.IsNullOrEmpty(subtitle))
    {
        Console.WriteLine(subtitleContent);
    }
    Console.WriteLine("╚════════════════════════════════════════════════════════════════════════════════════════╝");
}

然后你将其称为YourStaticClass.Header("Test", "Version 1.0");

它应该是这样的：

╔════════════════════════════════════════════════════════════════════════════════════════╗
║                                          Test                                          ║
║                                      Version 1.0                                       ║
╚════════════════════════════════════════════════════════════════════════════════════════╝

您可以使用90

替换windowsWidth中的Console.WindowWidth

更新 - 2019年2月 - 清除代码并制作动态尺寸

/// <summary>
/// Application header, also sets the console title
/// </summary>
/// <param name="title">Title of application</param>
/// <param name="subtitle">Subtitle of application</param>
/// <param name="foreGroundColor">Foreground color</param>
public static void Header(string title, string subtitle = "", ConsoleColor foreGroundColor = ConsoleColor.White, int windowWidthSize = 90)
{
    Console.Title = title + (subtitle != "" ? " - " + subtitle : "");
    string titleContent = CenterText(title, "║");
    string subtitleContent = CenterText(subtitle, "║");
    string borderLine = new String('═', windowWidthSize - 2);

    Console.ForegroundColor = foreGroundColor;
    Console.WriteLine($"╔{borderLine}╗");
    Console.WriteLine(titleContent);
    if (!string.IsNullOrEmpty(subtitle))
    {
        Console.WriteLine(subtitleContent);
    }
    Console.WriteLine($"╚{borderLine}╝");
    Console.ResetColor();
}

/// <summary>
/// Align content to center for console. Can be used with decoration if used inside menu or header
/// </summary>
/// <param name="content">Content to center</param>
/// <param name="decorationString">Left and right decoration, default is empty/none</param>
/// <returns>Center aligned text</returns>
public static string CenterText(string content, string decorationString = "", int windowWidthSize = 90)
{
    int windowWidth = windowWidthSize - (2 * decorationString.Length);
    return String.Format(decorationString + "{0," + ((windowWidth / 2) + (content.Length / 2)) + "}{1," + (windowWidth - (windowWidth / 2) - (content.Length / 2) + decorationString.Length) + "}", content, decorationString);
}

在C＃控制台应用程序中居中文本仅使用某些输入
