i have a textbox named passwordtextbox which has the passwordchar property of * to hide passwords. I also have a button named show to show passwords hidden by the passwordchar.Please i need help on how to go about it in c#?

推荐答案

将PasswordChar设置为\ 0 ...

Set PasswordChar to \0...

this.password.passwordchar='\0';

试试这个显示密码：

Try this to show password:

passwordtextbox.PasswordChar = char.MinValue;

我建议用checkBox替换show按钮，并且：

I suggest to replace the show button with checkBox and:

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
   this.passwordtextbox.PasswordChar = this.checkBox1.Checked ? char.MinValue : '*';
}

对于Web应用程序，请使用下面给出的代码

For web application use code given below

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
TextBox1.TextMode = (CheckBox1.Checked ? TextBoxMode.SingleLine : TextBoxMode.Password);
}

对于Windows应用程序，请使用下面给出的代码

For windows application use code given below

 private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
textBox1.PasswordChar = (checkBox1.Checked ? char.MinValue : '*');
}
