C# 将一个字符串[索引]与另一个字符串进行比较

我正在学习C#，我正在从头开始制作一个刽子手游戏，作为我的第一个项目之一

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

除了用正确猜出的字母替换隐藏单词的破折号的部分外，其他部分都可以工作

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

例如：-在你猜到G、E和A之后变成G-EA

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

我有一个for循环，逻辑上似乎它可以完成这项工作，但我不能对字符串或字符使用==运算符

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

for（int i=0；i如果
passMe
是一个只有一个字符的字符串，那么

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

if (answer[i] == passMe[0])

通过这种方式，您可以将用户输入的第i个位置的字符与第一个位置的字符进行比较

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

代码中还有一个严重错误。
你的循环偏离1，将其更改为

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

for (int i = 0; i < answer.Length; i++)

for（int i=0；i

NET中的数组从索引0开始，并且最大索引值总是比数组的长度小一个。
answer[i]指的是一个字符，passMe指的是一个字符串。（不是一个字符）

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

试试这个

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

for (int i = 0; i <= answer.Length; i++) //answer is a string "theword"
            {
                if (answer[i] == passMe[0]) //passMe is "A" for example
                {
                    hiddenWord = hiddenWord.Remove(i, 1);
                    hiddenWord = hiddenWord.Insert(i, passMe);
                }
            }

for（int i=0；i您在哪里定义
passMe
