The TreeNode.Add method in C# is used to add a new child node to the current TreeNode object. It takes the child node as a parameter and adds it to the list of child nodes of the current node. This method is commonly used in tree data structures to build a hierarchical structure of nodes, where each node can have multiple child nodes. Adding child nodes allows for organizing and representing data in a structured manner.
