推荐答案

据我所知，除非您要将信息存储在数据库中并在另一个数据库中检索它，否则Access是无关紧要的.表格-这不是最明显或最有效的方法！

您要在第二个表单上创建一个属性以接受名称:

As far as I know, Access is irrelevant unless you are going to store the info in a database and retrieve it in a different form - which is not the most obvious or efficient way to do it!

You want to create a property on the second form to accept the name:

public string UserName { get; set; }

然后在显示来自Form1的Form2之前设置值:

Then set the value before you display the Form2 from Form1:

Form2 f2 = new Form2();
f2.UserName = myTextBox.Text;
f2.ShowDialog();

在UserName属性的setter中，可以设置ComboBox值-并使用getter来检索当前选定的项目.

In the setter of the UserName Property, you can set the ComboBox value - and use the getter to retrieve the currently selected item.
