c# - Take parameter, determine if its an object or list<>; if list<> then loop and treat each item as object -

aim

take object or list<>.

if it's object (done).

if it's list<> (any type of list<>) loop through each item, , similar thing object each item, returning dictionary or array (return type not important @ moment).

what have far, object bit...

  public static dictionary<string, object> pick (object obj, array picklist) {     dictionary<string, object> dic = new dictionary<string, object> ();     foreach (string key in picklist) {       dic.add(key, obj.gettype ().getproperty (key).getvalue (obj, null));     }     return dic;   } 

so next need determine if it's object or list<>, i've tried sorts of generics, biggest problem i've come across casting list<> of unknown type.

any way of doing or understanding right steps, appreciated.

you this:

public static dictionary<string, object> pick(object obj, array picklist)  {     dictionary<string, object> dic = new dictionary<string, object> ();     ienumerable items = obj ienumerable ?? new[] { obj };     foreach(string key in picklist)      {         foreach(object item in items)         {             dic.add(key, item.gettype().getproperty(key).getvalue(item, null));         }     }      return dic; } 

note however, fail if try provide 2 or more items, since attempt add same key dictionary twice. fail if try pass object doesn't have 1 of specified properties. it's unclear want method in these cases, code seems example, you'll have figure detail out in real code.
