好的我假设你在转发器中有控制数据



foreach（rpt.Items中的RepeaterItem项目）

{

//获取每一行的下拉列表

DropDownList C =（DropDownList / textbox / any）item.FindControl（controler id）;



//获取下拉列表的选定值

string value = C.SelectedValue或C .Text或C.value;

}

ok i assume you have data in control in repeater

foreach (RepeaterItem item in rpt.Items)
{
//to get the dropdown of each line
DropDownList C= (DropDownList/textbox/any)item.FindControl(controler id);

//to get the selected value of your dropdownlist
string value = C.SelectedValue or C.Text or C.value;
}
