Recursion with delagates

i wish write following code error variable not inialized.

delegate void recur(treenodecollection nodes);

public void showkeywords(string message)

{

list<treenode> list = new list<treenode>();

recur recur = delegate(treenodecollection nodes)

{

foreach (treenode node in nodes)

{

list.add(node);

recur(node.nodes);

}

};

recur(treeview1.nodes);

--

 

error

error 12 use of unassigned local variable 'recur' 

it possible modify

recur recur = delegate(treenodecollection nodes)

to

recur recur = null;

recur = delegate(treenodecollection nodes)

but think worth modify c# bit make first code possible.

the problem, i'm seeing in code have not initialized nodes where, nodes defined , intialized?
