Want to change a variable into * in c#

Question

I have a string called password which my user can define with whatever, kim123 is an example.

So later in the code I want to say something like: "You have entered (password but using asterisks) as your password."

If you are still unclear by what I mean, I basically want to turn the password he/she chose into stars:

password = hey123

"You have entered ****** as your password"

You don't say what UI Framework you are using. If you are using [tag:winforms], are you looking for [How to set a text box for inputing password in winforms?](https://stackoverflow.com/q/2555984) If [tag:wpf] then maybe [How can I make a TextBox be a “password box” and display stars when using MVVM?](https://stackoverflow.com/q/1119605)? But you should never, ever **save** an unhashed copy of a user's password, see e.g. [How to securely save username/password (local)?](https://stackoverflow.com/q/12657792) or [C# - Securely storing a password locally](https://stackoverflow.com/q/16957492). — dbc, May 19 '18 at 21:24
If you are using asterisks to be more secure, displaying an accurate length of what the password is goes against that. — docmanhattan, May 19 '18 at 21:26

Then you generate so like

string pass = new String('*', password.Length); //will generate * as big as length of pasword
Console.WriteLine("You have entered {0} as your password", pass);

like: string password = "hello123"; string pass = new password('*', password.Length); ? – Jackson Mac Dislike May 19 '18 at 22:38
@JacksonMacDislike NO, like my answear ... try the posted code and it would work – Rahul May 19 '18 at 22:53
Yeah I figured it out myself actually – Jackson Mac Dislike May 19 '18 at 23:31
@JacksonMacDislike Why create the variable `password`, you don't even use it? – AustinWBryan May 20 '18 at 02:12
