Question

Here’s the function:

private static void AddToTree(TreeNode target, DataRow dataRow)
{
    var node2 = new TreeNode(dataRow["name"].ToString())
    {
        ImageIndex = target.ImageIndex,
        SelectedImageIndex = target.SelectedImageIndex,
        Tag = dataRow
    };
    TreeNode node = node2;
    target.Nodes.Add(node);
}

I see similar code throughout the codebase. Why not just add node2 to the target nodes and not create another variable? Am I missing something?

You’re not missing anything. This code is redudant.

TreeNode node = node2; //<--- Assign the object reference of node2 to node. 
                       //     There is no object copy or wathever.
