c# - Accessing all the nodes in TreeView Control

I have a TreeView Control with set of nodes and child nodes. For example:

ROOT has A,B,C.

A has a1, a2, a3 and then that a1, a2 also contains some nodes like x1, x2, x3 and so on. Like this many subnodes are there. I know it is possible to use loops with a for loop.

I just want to access all the nodes in TreeView control using one or two for loops.

Is there any algorithm for that or is there any other way?

One more question: Is it is possible to have the path of a tree node in an object or in a string using any library functions? For example:

string S = TreeView1.Nodes[i].Nodes[j].Nodes

Don't use nested loops, but go for an recursive solution like:

void ListNodes( TreeNode node )
{
  foreach( var subnode in node.Nodes )
  {
    ListNodes( subnode );
  }
  // Print out node
}

Call this function for your root node.

For your additional question: check the FullPath property.
