I can't see what's wrong with this code:
var listShoppingCart = Session["ShoppingCart"];
foreach (var item in listShoppingCart)
{
}
I get a red line below the listShoppingCart in the foreach loop. When I hover over the red line, the messages is that Foreach statement cannot operate on variables type 'object' because 'object' does not contain a public definition for 'GetEnumerator'
I declare the list with a session like this:
Session["ShoppingCart"] = new List<Products>();
You need to cast the session object
var listShoppingCart = Session["ShoppingCart"] as List<Products>;
if (listShoppingCart != null)
{
// Do stuff...
}
In the above code, we get the object located in the session at key "ShoppingCart" and cast that object to a List<Products>. If the cast cannot be done, then listShoppingCart will be null.
Because Session is of Type HttpSessionState and this implements ICollection.
Session values are stored in Dictionary<string,object> which implements ICollection. You need to type cast object to appropriate to enumerate over your list.
