StringBuilder在隐藏消息中显示空格

Question

所以从本质上讲，我希望displayToPlayer变量具有自动添加的空格，但是我不确定如何实现。

如何在不使用转弯的情况下将空格自动添加到隐藏的消息中，或者将其添加到猜到的字母提示中。

Answer 1

如果我对您的理解正确，这可能会起作用

const food = ratings.reduce((sum, { food }) => sum + food, 0) / ratings.length;

console.log("FOOD", food)

基本上是说，如果for (int i = 0; i < quoteToGuess.Length; i++) { displayToPlayer.Append(quoteToGuess[i] == ' ' ? ' ' : '*'); } 中i的索引处的字符是quoteToGuess，则添加' '，如果不添加' '

?: Operator (C# Reference)

  

条件运算符（？:)，通常称为三元运算符   条件运算符，根据值返回两个值之一   布尔表达式。以下是条件句的语法   运算符。

Strings and indexes

  

索引是Char对象（不是Unicode字符）在以下位置的位置   一个字符串。索引是从零开始的非负数   从字符串的第一个位置开始，即索引位置零

Answer 2

您可以使用StringBuilder摆脱System.Linq并完全使用for循环：

var displayToPlayer = new string(quoteToGuess.Select(c => c == ' ' ? ' ' : '*').ToArray());

如果由于似乎未定义Select()而出现错误，请将其添加到文件顶部：
