我是个菜鸟，希望给点代码。

Answer 1

#region TreeView控制节点的设置
/// <summary>
/// 导航设置
/// </summary>
private void treeView1_DoubleClick(object sender, EventArgs e)
{
if (treeView1.SelectedNode.Text == "添加借阅图书")
this.tsbLendBook_Click(null, null);
else if (treeView1.SelectedNode.Text == "添加归还图书")
this.tsbReturnBook_Click(null, null);
else if (treeView1.SelectedNode.Text == "查询借阅记录")
this.MenuItemSelectLend_Click(null, null);
else if (treeView1.SelectedNode.Text == "添加图书")
this.MenuItemAddBook_Click(null, null);
else if (treeView1.SelectedNode.Text == "查询图书")
this.MenuItemSelectBook_Click(null, null);
else if (treeView1.SelectedNode.Text == "查询读者信息")
this.MenuItemSelectReaders_Click(null, null);
else if (treeView1.SelectedNode.Text == "添加读者信息")
this.MenuItemAddReader_Click(null, null);
else if (treeView1.SelectedNode.Text == "读者类别管理")
this.MenuItemReaderTypeManagement_Click(null, null);
else if (treeView1.SelectedNode.Text == "查询读者借阅记录")
this.MenuItemSelectReaderLend_Click(null, null);
else if (treeView1.SelectedNode.Text == "收缴罚款")
this.MenuItemCaptureFine_Click(null, null);
else if (treeView1.SelectedNode.Text == "管理员管理")
this.MenuItemAdminManagement_Click(null, null);
else if (treeView1.SelectedNode.Text == "用户管理")
this.MenuItemUserManagement_Click(null, null);
else if (treeView1.SelectedNode.Text == "修改用户密码")
this.MenuItemUpdateUser_Click(null, null);
else if (treeView1.SelectedNode.Text == "按借阅统计")
this.MenuItemLendCount_Click(null, null);
else if (treeView1.SelectedNode.Text == "按图书统计")
this.MenuItemBookCount_Click(null, null);
}
#endregion

Answer 2

treeView1.Nodes[0].ContextMenuStrip = new ContextMenuStrip();
treeView1.Nodes[0].Nodes[0].ContextMenuStrip = new ContextMenuStrip();

Answer 3

1、程序判断，根据点击节点

动态对ContextMenu进行MenuItem加载

Answer 4

动态添加，查看如果是父节点显示父节点的右键菜单。
