在*中显示密码字符 [英] To display password characters in *

问题描述

我已经编写了代码以在*中显示我的密码字符，但它也是输入作为我的密码的一个字符。你可以帮帮我吗？

下面是我的代码：

Hi,

I have written the code to display my password characters in "*" but it is also consediring "enter" as one character for my password. Can you please help me with this?
Below is my code:

Console.Write("Enter Password :");
ConsoleKeyInfo key;String pwd="";
do
{
    key = Console.ReadKey(true);

    if (key.Key != ConsoleKey.Backspace)
    {
        pwd += key.KeyChar;
        Console.Write("*");                                    
    }

} while (key.Key != ConsoleKey.Enter);

pwd = Console.ReadLine();

请告诉我哪里出错了。

注意：

我没有任何方法或东西返回密码。

推荐答案

使用while循环代替do while ...它将解决你的问题

use the while loop instead of do while ... it will solve your problem

更改你的代码如下： br />

Change your code something like this:

Console.Write("Enter Password :");
ConsoleKeyInfo key; String pwd = "";
do
{
    key = Console.ReadKey(true);

    if (key.Key != ConsoleKey.Backspace && key.Key!=ConsoleKey.Enter)
    {
        pwd += key.KeyChar;
        Console.Write("*");
    }

} while (key.Key != ConsoleKey.Enter);

Console.ReadLine();
Console.WriteLine(pwd);
Console.ReadKey();

或

如果你想使用while循环分配key的值，就像这样：

OR
If you want to use while loop assign the value of key like this:

ConsoleKeyInfo key='\0';

祝你好运

享受！

Good Luck
Enjoy!

编写如下代码。

Write your code as below.

Console.Write("Password :"); 
ConsoleKeyInfo key;
key=Console.ReadKey(true);
while (key.Key != ConsoleKey.Enter) 
{ 
   if (key.Key != ConsoleKey.Backspace) 
   { 
     pwd += key.KeyChar; 
     Console.Write("*"); 
   } 
   key = Console.ReadKey(true); 
} 
pwd = Console.ReadLine();
