推荐答案

尝试:

NewMember_UserControl nmuc = new NewMember_UserControl();
Controls.Add(nmuc);

严格来说，它可以满足您的要求，但我不禁会以为您真正想要做的是完全不同的东西……

Strictly speaking, it''ll do what you asked for, but I can''t help thinking that what you actually want to do is something quite different altogether...

进一步了解Griff "的绝佳答案，您可能会发现最好有一个单独的MemberControl支持三种模式[new，amend和delete]，这些模式可以更改启用的字段以及表单产生的操作.
对相同的事物显示相同的控件是一种很好的设计方法.在您的情况下，您需要一个显示成员的控件，该控件无论模式如何都不会改变，并且在后台的行为会稍有不同.

Further to Griff''s excellent answer, you may find it better to have a single MemberControl that supports three modes [new, amend and delete] that changes which fields are enabled and the action resulting from the form.
It is a good design approach to show the same control for the same thing. In your case you want a control that displays a member, that is unchanged irrespective of the mode, that will have slightly different behaviour behind the scene.
