c# - It shows more items in array than expected -

it shows more times expected , when add 1 item , stackable adds stack....but not once 2 times.

backpack simple

public void additems(b_item newitem) {     if (items.count < maxslots)     {         foreach (var in items.toarray())         {             if (i.item_name == newitem.item_name )             {                 if (i.is_stackable == true && i.stacksize < 500)                 {                     i.stacksize += 1;                 }             }             else             {                 items.add(newitem);             }         }      }     else     {         items.add(newitem);     }                    }  private void remove(b_item itemid) {      (int = 0; < items.count; i++)     {         if (items.count > 0)         {             items[i].stacksize -= 1;         }              items.removeat(i);     } } 

why draw more items specified value itemsperpage in inventory. constructor

inventory thiss = new inventory(new playerback(),2,1,32,32, 32, new vector2(0, 0)) 

ok, sorry comment it's abit wrong. here correct method:

public void additems(b_item newitem)         {             if (items.count < maxslots)             {                 foreach (var in items.toarray())                 {                     if (i.item_name == newitem.item_name )                     {                         if (i.is_stackable == true && i.stacksize < 500)                         {                             i.stacksize += 1;                             return;                         }                     }                  }              }             items.add(newitem);          }
