I am using ArrayList in Asp.net I want to extract specific items . My code is
ArrayList items = (ArrayList)Session["mycart"];
foreach(var v in items)
{
}
but this is not working . I want to get value like
v.myvalue;
My arralist is filled with several items coming from prevoius page.
The issue is that ArrayList stores all elements as object. You need to perform a cast to the type of object that contains myvalue.
For example
ArrayList items = (ArrayList)Session["mycart"];
foreach(var v in items)
{
MyObject o = v as MyObject;
if (o != null)
{
// do stuff with o.myvalue
}
}
It may be better to just use the generic List class rather ArrayList, although you may have a perfectly reason for doing otherwise. Generally, you should use the generic (e.g. List<MyObject>), not only for performance but also ease of use.
List<T>instead ofArrayList
