回答1:

You can get it from the Password property.

回答2:

You may extract it from Password property:

passwordBox.Password.ToString()

回答3:

If using a MaskedTextbox you can use the .text property. For example:

private void btnOk_Click(object sender, EventArgs e)
{
    if ( myMaskedTextbox.Text.Equals(PASSWORD) )
    {
        //do something
    }         

}

You may not want to store the password in clear text in memory, from the msdn doc you should use SecurePassword in order to prevent that.

Example: SecureString myPass = passwordBox.SecurePassword

I use below code to get the length of PasswordBox

PasswordVariableName.Password.Length

It will certainly work on wp8
