C# StringBuilder在隐藏消息中显示空格

因此，本质上我希望displayToPlayer变量自动添加空格，但我不太确定如何实现这一点

我怎样才能让空格自动添加到隐藏消息中，而不使用回合或将其添加到猜测的字母计数中

如果我理解正确的话，这可能会奏效

for (int i = 0; i < quoteToGuess.Length; i++)
{
    displayToPlayer.Append(quoteToGuess[i] == ' ' ? ' ' : '*');
}

它的基本意思是，如果quoteToGuess中i的索引处的字符是“”，那么添加“”，如果不是添加“*”

条件运算符？：，通常称为三元运算符 条件运算符，根据值返回两个值中的一个 布尔表达式的。以下是条件语句的语法 接线员

索引是字符对象的位置，而不是Unicode字符在索引中的位置 一串。索引是从零开始的非负数 从字符串中的第一个位置开始，即索引位置零

您可以使用System完全摆脱StringBuilder和for循环。Linq:

如果由于似乎未定义Select而出现错误，请在文件顶部添加以下内容：

using System.Linq;

顺便说一句，不需要使用StringBuilder。Regex.Replace应该可以这样工作：Regex.Replaceinput，[^]1我注意到这个解决方案的一个小问题是它仍然需要用户猜测space@BradleyWilson-如果使用nonSpaceChars=quoteToGuess.Replace、.Length之类的内容；您可以不使用字符获取字符串的长度。您的异常处理在我看来非常糟糕。
