Method / Casting Problem

i wish write sorting algorithm work list of comparable items.  figure method definition should this:

code snippet

static void sort(ilist<icomparable> list)
{
  // method implementation
}

that works expect except must ugly cast every time call method:

code snippet

list<string> somestrings = new list<string>();
// add items
sort((ilist<icomparable>)somestrings);

i want way this:

code snippet

sort(somestrings);

my problem more casting else.  there way can tell compiler want objects matching ilist<icomparable> type automatically cast?

hope clear asking.  appreciated.

> works expect except must ugly cast every time call method:

 

that code not work; @ run time it fails follows:

 

unable cast object of type 'system.collections.generic.list`1[system.string]' type 'system.collections.generic.ilist`1[system.icomparable]'.

 

you see, ilist<icomparable> not interface implemented list<string> cast fails.  (this common misunderstanding of how generics work.)

 

however, following signature should want:

 

code snippet

static void sort<t>(ilist<t> list) where t : icomparable

{

// method implementation

}
