这是包含方法,它写入隐藏的字母。当我按下退格键时,我需要以某种方式从控制台中删除 char *。
private static string Password()
{
bool enter=true;
string pass="";
do
{
char letter = Console.ReadKey(true).KeyChar;
if (letter == (char)13)
{ enter = false; }
else if (letter == (char)8 && pass.Length >= 1)
{
pass = pass.Remove(pass.Length - 1);
Console.Write("\b");
}
else
{
pass += letter;
Console.Write("*");
}
} while (enter);
Console.WriteLine();
return pass;
}
我搜索了一个答案,但命令 Console.Write("\b");但它似乎无法正常工作。
最佳答案
您可以将光标的位置设置回 1,写入一个空字符,然后再将其移回。像这样:
private static string Password()
{
bool enter = true;
string pass = "";
do
{
char letter = Console.ReadKey(true).KeyChar;
if (letter == (char)13)
{ enter = false; }
else if (letter == (char)8 && pass.Length >= 1)
{
pass = pass.Remove(pass.Length - 1);
Console.CursorLeft--;
Console.Write('\0');
Console.CursorLeft--;
}
//Additionally, don't print backspaces if it's the first character.
else if (letter != (char)8)
{
pass += letter;
Console.Write("*");
}
} while (enter);
Console.WriteLine();
return pass;
}
