Button_Click (Sender sender,event e)
{
foreach (DataListItem item in Datalist1.items)
{
CheckBox cbox= (CheckBox) item. FindControl ("CheckBox1");
if (Cbox. Checked)
{
Product model= (product) e.item.dataitem;//product as the entity class for the data
Deletemodel (model);//delete a record of the method, the parameter can also be a primary key
}

Another way is to put the data primary key value of all the selected checkbox into an array, to the deletion method, so that when the condition is where ID in @ids
Or put the model into a collection of generic objects, which are deleted as a whole, and the two methods interact with the database only once
