对treeview节点的复制，粘贴和出现右击菜单

在写项目的时候，我们都会在按钮上去实现一些添加，修改等等的操作，有时候复制，粘贴等大部门都是用按钮的形式，如果是右击往往这样会让用户感觉到软件的灵活性，因为用户在使用操作系统的时候都习惯了右击对数据进行复制，粘贴等操作，所有在树形节点上除了用按钮的形式实现复制，粘贴等功能外，我想菜单上也能够实现的话，会非常的好，能够给用户很好的体验。
实现粘贴功能代码如下:
/// <summary>
        /// 实现粘贴的功能
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void barButtonItem粘贴_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            //如果没有复制
            if (this.copyNode == null)
            {
                return;
            }
            //如果目标节点为空或目标节点在外面
            if (this.treeView1.SelectedNode == null || this.treeView1.SelectedNode == this.treeView1.Nodes[0])
            {
                MessageBox.Show("不能粘贴在所有部门以外", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
            //如果目标节点是自己或自己的子节点
            if (this.treeView1.SelectedNode == this.copyNode || !IsNode(copyNode))
            {
                MessageBox.Show("不能粘贴在自己及自己的子节点上", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
            //添加节点
            AddNode(this.treeView1.SelectedNode, this.copyNode);
            //刷新
            CreateTree(this.treeView2, "All");
        }
/// <summary>
        /// 粘贴子接点
        /// </summary>
        /// <param name="sNode"></param>
        /// <param name="cNode"></param>
        public void AddNode(TreeNode sNode, TreeNode cNode)
        {
            //取出当前节点的编号
            int mId = ((TreeNodeClass)sNode.Tag).ID;
            //连接数据库
            SqlConnection sqlConn = new SqlConnection(sqlConnectionBuilder.ConnectionString);
            SqlCommand comm = sqlConn.CreateCommand();
            sqlConn.Open();
            try
            {
                //执行插入语句
                comm.CommandText = " INSERT INTO 人事部门信息(名称,父编号,停止,单位编号) VALUES('" + cNode.Text + "'," + mId + ",0,@单位编号); SELECT @@IDENTITY";
                //以下为了防止sql语句攻击，较安全
                comm.Parameters.Add("@单位编号", SqlDbType.Int);
                comm.Parameters["@单位编号"].Value = ((TreeNodeClass)sNode.Tag).bh;
                //获取目标节点的编号
                int copyId = int.Parse(comm.ExecuteScalar().ToString());
                //执行更改语句
                comm.CommandText = " UPDATE 人事部门信息 SET 顺序号 = 编号 WHERE 编号 = " + copyId;
                comm.ExecuteNonQuery();
                //创建类实例
                TreeNodeClass tag = new TreeNodeClass();
                //为类的属性赋值
                tag.ID = copyId;
                tag.Text = cNode.Text;
                tag.Type = "名称";
                tag.bh = ((TreeNodeClass)sNode.Tag).bh;
                //取出要复制的节点值
                TreeNode node = new TreeNode(cNode.Text);
                //设置图标索引
                node.ImageIndex = 1;
                node.SelectedImageIndex = 1;
                node.Tag = tag;
                //添加新的节点
                sNode.Nodes.Add(node);
                //如果要复制的数量小于1
                if (cNode.Nodes.Count < 1)
                {
                    return;
                }
                //依次添加
                for (int i = 0; i < cNode.Nodes.Count; i++)
                {
                    AddNode(node, cNode.Nodes[i]);
                }
            }
            catch (System.Exception e)
            {
                MessageBox.Show(e.Message);
            }
            finally
            {
                //关闭数据库资源
                close(comm,sqlConn);
            }

        }
实现复制的功能：
/// <summary>
        /// 实现复制的功能
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void barButtonItem复制_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
        {
            // 如果没有选中节点或没有父节点
            if (this.treeView1.SelectedNode == null || this.treeView1.SelectedNode.Parent == null)
            {
                MessageBox.Show("根节点不能复制", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
            //把当前节点的信息赋值给一个节点
            this.copyNode = this.treeView1.SelectedNode;
        }
上面就完成了在树节点上对数据的复制，粘贴了，然后我们在实现右击功能，把上面的功能添加到事件中去：
/// <summary>
        /// 右击事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void MouseDown右击事件(object sender, MouseEventArgs e)
        {
            //判断你点的是不是右键
            if (e.Button == MouseButtons.Right)
            {
                //获取右击的位置
                Point ClickPoint = new Point(e.X, e.Y);
                //取出位置，赋给节点
                TreeNode CurrentNode = treeView1.GetNodeAt(ClickPoint);
                //判断你点的是不是一个节点
                if (CurrentNode != null)
                {
                   //如果是节点，就出现右击菜单
                   CurrentNode.ContextMenuStrip = contextMenuStrip右击菜单;
                        
                }
                //选中这个节点
                treeView1.SelectedNode = CurrentNode;
                }
            }
        /// <summary>
        /// 右击粘贴事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void 粘贴ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            barButtonItem粘贴.PerformClick();
        }
        /// <summary>
        /// 右击复制事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void 复制ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            barButtonItem复制.PerformClick();
        }
这样程序就更加的完美了
