c# - Is passing WinForm Controls between Classes dangerous/inefficient? -

since projects create contains listviews got idea class contains important functions modify listview. this:

mainform:

listviewfunctions lvf = new listviewfunctions(); listview newlv = new listview(); newlv = lvf.additem(newlv, new list<string> { "item", "subitem1", "subitem2" }); 

class:

public class listviewfunctions {    public listview additem(listview lv, list<string> inputstrings)    {        if (inputstrings.count > 0)        {            (int = 0; < inputstrings.count; i++)            {                if (i == 0)                    lv.items.add(inputstrings[0]);                else                    lv.items[lv.items.count - 1].subitems.add(inputstrings[i]);            }        }        return lv;     } } 

however i'm not sure if passing controls class above considered dangerous nor how affect performance. i'm hoping can answer if safe or not.

thanks in advance!

i use helper class have done if planning make generic utilise class on other types.

creating custom control extending listview may preferable way implement listview methods.

public class mycustomlistview : listview {  //...  }
