替代＆QUOT; ＆QUOT;创建包含多个空格字符的字符串 [英] Alternatives to " " for creating strings containing multiple whitespace characters

问题描述

我不知道是否有在C＃中创造的空间更OO的方法。

I'm wondering if there's a more OO way of creating spaces in C#.

从字面上空间code！

Literally Space Code!

我目前有标签+ =新的String（）; ，我不禁觉得这是有点让人想起使用 而不是的String.Empty 。

I currently have tabs += new String(" "); and I can't help but feel that this is somewhat reminiscent of using "" instead of String.Empty.

我可以使用什么来创建空间，是不是，？

What can I use to create spaces that isn't " "?

推荐答案

您可以写

" "

而不是

new String(' ')

帮助吗？

根据你做什么，你可能想看看进入 StringBuilder.Append 超载接受一个字符和一个'重复'计数：

Depending on what you do, you might want to look into the StringBuilder.Append overload that accepts a character and a 'repeat' count:

var tabs = new StringBuilder();
tabs.Append(' ', 8);

或进入字符串 构造从性格上的一个构造一个字符串'重复'计数：

or into the string constructor that constructs a string from a character a 'repeat' count:

var tabs = new string(' ', 8);

下面是一个enterprisey OO解决方案，以满足您的所有空间一代的需要：

Here's an enterprisey OO solution to satisfy all your space generation needs:

public abstract class SpaceFactory
{
    public static readonly SpaceFactory Space = new SpaceFactoryImpl();

    public static readonly SpaceFactory ZeroWidth = new ZeroWidthFactoryImpl();

    protected SpaceFactory { }

    public abstract char GetSpace();

    public virtual string GetSpaces(int count)
    {
        return new string(this.GetSpace(), count);
    }

    private class SpaceFactoryImpl : SpaceFactory
    {
        public override char GetSpace()
        {
            return '\u0020';
        }
    }

    private class ZeroWidthFactoryImpl : SpaceFactory
    {
        public override char GetSpace()
        {
            return '\u200B';
        }
    }
}
