Question

Hej，有谁知道我怎样才能让我猜字母的方法记住之前的猜测？目前它把所有“正确”的猜测变成最后猜对的字母:(

public void myGuess(char letter)
{
    string wordToGuess = label4.Text;
    string wordToShow = label5.Text;

    for (int i = 0; i < wordToGuess.Length; i++)
    {
        if (wordToGuess[i] == letter || wordToGuess[i] == wordToShow[i])
            wordToShow = wordToShow.Remove(i, 1).Insert(i, Char.ToString(letter)); 
    }

    label5.Text = wordToShow;

    if (wordToGuess == wordToShow) 
        this.Close();

    Form Win = new Win();
    Win.Show();
}

Answer 1

有一个全局的 char 列表，每次猜测后都添加到它

List<char> guesses = new List<char>();

然后在你的方法中添加到它

guesses.Add(letter);

然后你可以用这个检查

if (guesses.Contains(letter))
{
    //DoSomething
}
