Like to see few real life usage of Binary Tree C#

Question

whenever we read something about BTree then this kind of program shown in article with code.
code as follows.
Main File
static void Main(string[] args)
//Creating the Nodes for the Tree
Node<int> tree = new Node<int>('6');
tree.Left = new Node<int>('2');
tree.Right = new Node<int>('5');
Console.WriteLine("Binary Tree Display");
Console.WriteLine(tree.Data);
Console.ReadLine();
Node Class
class Node<T> where T : IComparable
private T data;
public Node<T> Left, Right;
public Node(T item)
data = item;
Left = null;
Right = null;
public T Data
set { data = value; }
get { return data; }
in our daily program where we can use btree to store and retrieve data? so please all share your idea how you guys use btree in your program in real life application development. thanks

"in our daily program where we can use btree to store and retrieve data?"
Given that your example mentions IComparable I suppose you're talking specifically about binary search trees, not any binary tree. In that case it's unlikely that you'll see anyone using a binary tree directly. People use collections such as SortedDictionary and
such collections are usually implemented using binary search trees.
Note that btree isn't a good abbreviation for binary tree, there is such a data structure called B-Tree and it's not the same thing as binary tree. Incidentally B-Trees are also used for searching - databases use them for indexes and filesystems
use them to store directory entries.
@Joel Engineer: "Binary trees structures are built into the Net Library Hash Class"
Binary trees and hash tables have nothing in common.
