Simple - the two objects you create in the two methods are different. Anyway, this is wrong on so many levels. Your classes should be nouns, not verbs. Also, you don't even need a new class to store the user name in this case. In your form, just declare private string _userName; Then, in your methods, you can read and modify _userName directly.
