如下内容内容是关于二叉搜索树插入算法C#演示的内容，希望能对大伙有帮助。
public class BinaryTreeNode
{
public BinaryTreeNode Left { get; set; }

public BinaryTreeNode Right { get; set; }

public int Data { get; set; }

public BinaryTreeNode(int data)
{
this.Data = data;
}
}

public void InsertIntoBST(BinaryTreeNode root, int data)
{
BinaryTreeNode _newNode = new BinaryTreeNode(data);

BinaryTreeNode _current = root;
BinaryTreeNode _previous = _current;

while (_current != null)
{
if (data < _current.Data)
{

}
else if (data > _current.Data)
{
_previous = _current;
_current = _current.Right;
}
}

if (data < _previous.Data)
_previous.Left = _newNode;
