DataTable dt =

//调用方法:

//首先添加一个ComboBoxItem类

//首先添加一个SetCls类
public

public

// 赋值方法:(使用ArrayList 要先引用命名空间using System.Collections;)
ArrayList lists =
new
ArrayList();
lists .Add(
new
SetCls (
"1"
,
"活动"
));
lists .Add(
new
SetCls (

"生活"

this
.COMBOX.DisplayMember =
"pID"
;
this
.COMBOX.ValueMember =
"pName"
;
this
.COMBOX.DataSource = lists;
string
com_sex_value = COMBOX.SelectedValue.ToString();
我用DataSet填充的数据库中的内容(我这个是直接赋值,并不像上面三个添加值给ComBox)
DataSet ds_zubie =
new
DataSet();
da =
new
SqlDataAdapter(sql_zubie, PublicDB.DBzbw);
da.Fill(ds_zubie,
"zubie"
);
com_paidan.DataSource = ds_zubie.Tables[
"zubie"
].DefaultView;//绑定数据源
com_paidan.ValueMember =
"zubie_id"
;//赋值Value
com_paidan.DisplayMember =
"zubie_name"
;//赋值显示名称
string
com_zubie_id = com_paidan.SelectedValue.ToString();
