What i want to achieve(in runtime):
A root named "Home" with nodes added to it named "A","B","C" and so on til
"Z".
I want these subnodes named accordingly Home_A, Home_B and so on, in the
code so they can be accessed like Home_G.Node.Add("bla bla").

Basicly, i'm trying to make a "Register" where you can add names, they're
sorted and put in the correct node in the tree. The sorting part i've
figured out.. I have added the nodes in runtime, "manually", without using
loops but it looks very shabby and takes up alot of code. The loop i've been
trying to get working looks like this:

My aproach:
**************************
trTest.Nodes.Add("Home");
for(int i=65; i<91; i++)
{
string ch = Convert.ToString(Convert.ToChar(i));
string create = "Home_" + ch;
TreeNode (Convert.ToString(create)) = new TreeNode(ch); //Se note
trTest.Nodes[0].Nodes.Add(create);
}
//Note: Well... Since TreeNode is a class.. the context it's given
//... in isn't valid... any ideas, pointers, suggestions?
***************************

{
string ch = Convert.ToString(Convert.ToChar(i));
string create = "Home_" + ch;
TreeNode (Convert.ToString(create)) = new TreeNode(ch); //Se note
trTest.Nodes[0].Nodes.Add(create);
}
//Note: Well... Since TreeNode is a class.. the context it's given

At this point, there's no need to create a variable with a specific
name:

TreeNode parent = trTest.Nodes.Add("Home"), child;
char suffix;

for (int i = 65; i < 91; i++)
{
suffix = (char) i;
child = parent.Nodes.Add("Home_" + suffix);
// do whatever you need to with child
}
