Question

c#(winform)combobox怎么绑定数据？又怎么获取？

Answer 1

添加两个combobox,
public
partial
class
form1
:
form
{
public
form1()
{
initializecomponent();
bind(this.combobox1);
bind2(this.combobox2);
}
//绑定datatable
private
void
bind(combobox
combobox)
{
datatable
dt
=
new
datatable();
dt.columns.add("text");
dt.rows.add("北京");
dt.rows.add("河北");
combobox.datasource
=
dt;//绑定数据
combobox.displaymember
=
"text";//显示的字段
}
//手动绑定
private
void
bind2(combobox
combobox)
{
combobox.items.add("上海");
combobox.items.add("天津");
}
}

Answer 2

this.cbbUserlist.DataSource
=
dtForList;
this.cbbUserlist.ValueMember
=
"ID";
this.cbbUserlist.DisplayMember
=
"名称";
dtForList是你从数据库中读取出的表
string
userid
=
this.cbbUserlist.SelectedValue.ToString();这个是获取ID的代码，你转换成int型就可以了
