I got this class which raises same type of exception, how do i capture this exception and display appropriate error message. Here is what i do now.
public bool ChangePassword(oldPassword,newPassword)
{
if(oldPassword != savedInDatabase)
{
throw new ArgumentException("Your old password is not same as one saved in our database")
}
if(string.IsNullOrEmpty(oldPassword) || string.IsNullOrEmpty(newPassword))
{
throw new ArgumentException("Your old or new password is empty of null");
}
}
and i do the below,
try
{
}
catch(ArgumentException ex)
{
if(ex.Message.contains("Your old or"))
{
messagebox.show("Either your old or new password is empty or null")
}
...
}
