推荐答案

为什么不查询它并将其存储在你的表类列表中，如

列表< admin> admins_CBOx =新列表< admin>（）;

并将其绑定到组合框，例如

Combobox1.DataSource = admins;



并使用组合框活动中的selectedvalue事件



并在那里使用方法类似



Combobox1.selectedValue =你的一些变量并做你想做的事情



既然你选择了SeletedValue就需要了只需从表类创建另一个valiable，例如



admin TempadminCBBOX = Combobox1.SelectedValue;



和你得到你在组合框中选择的东西;



欢呼！

why don't you query it out in and store it in the list of your table class like
List<admin> admins_CBOx = new List<admin>();
and bind it to combobox like
Combobox1.DataSource = admins;

and use selectedvalue event from combobox event

and use there methodlike

Combobox1.selectedValue = some of your variable and do what ever you want to do with it

Since you SeletedValue got everthing you need just create another valiable from a table class like

admin TempadminCBBOX = Combobox1.SelectedValue;

and you got what you selected in combobox;

Cheer!
