从会话中的列表中删除特定项目

Question

List<ShoppingCartView> removeitem = (List<ShoppingCartView>)Session["ShoppingView"];

我想在点击该特定产品时删除一行。例如，如果我单击产品xxx并想要从Session [“ShoppingView”]中删除产品xxx，则列表的其余部分应保持不变。

Answer 1

您可以使用Remove

Session["ShoppingView"] = (List<ShoppingCartView>)Session["ShoppingView"].Remove((List<ShoppingCartView>)Session["ShoppingView"].Where(x => x.id== sessionItemToRemove).ToList());

Answer 2

你必须相应地编辑条件

var list = (List<ShoppingCartView>)Session["ShoppingView"];
Session["ShoppingView"] = list.Where(x => x.ProductName!= "pname").ToList();

Answer 3

你可以这样做

List<string> foo =  Session["ShoppingView"];  
foo.Remove("xxx");  
Session["ShoppingView"] = foo;
