c# - ListBox shows System.Collection.ArrayList -

i have listbox on 1 page carries items in listbox list box on page, when second listbox shows "system.collection.arraylist".

page1:

protected void btncheckout_click(object sender, eventargs e) {      session["name"] = nametext.text;     session["phonenumber"] = phonetextbox.text;     session["address"] = addresstext.text;     session["email"] = emailtext.text;     session["city"] = citytextbox.text;     arraylist al = new arraylist();     (int = 0; < itemlistbox.items.count; i++)     {         if (itemlistbox.items[i].selected == true)         {             al.add(itemlistbox.items[i].value);         }     }     session["selectedvalues"] = al;     response.redirect("invoice.aspx");  } 

page2:

protected void page_load(object sender, eventargs e) {     string phonenumber = (string)(session["phonenumber"]);     string homeaddress = (string)(session["address"]);     string name = (string)(session["name"]);     string email = (string)(session["email"]);     string city = (string)(session["city"]);     phonelabel.text = phonenumber;     addresslabel.text = homeaddress;     namelabel.text = name;     emaillabel.text = email;     citylabel.text = city;     invoicelistbox.items.add(session["selectedvalues"].tostring()); } 

all other label session work, listbox not work

that's because you're adding collection's tostring() result (a string) single item.

try .addrange instead
