问题描述

是将MenuStrip中的所有DropDownItems列出来，供用户选择，被选中的项将在ToolStrip被显示出来，并且可以使用与其对应的DropDownItem的事件.

其工作流程可以分解如下图所示：

实际上这个图所描述的正是我们上面说的一样，只是换作图形表示而已，但这样一来程序的结构就变得清晰起来了。可以看出，整个问题实际上被分解成了三个部分，即遍历菜单栏所有可用的DropDownItems，提供用户的选择界面，和为工具栏动态添Items及其事件。提供用户的选择界面这部分内容没什么技术含量，可以用任何一种你喜欢的方式实现，没什么好说的。下面我将重点说一下遍历菜单栏所有可用的DropDownItems，和为工具栏动态添Items及其事件这两部分。

一、遍历菜单栏所有可用的DropDownItems

菜单栏的结构实际上是典型的“森林”，而每一个下拉菜单(DropDownItem)都是一棵树。

面对这种问题最好的解决方式就是递归。很多人提到递归就头大，其实对于了解递归的人来说递归很简单。尤其是树的遍历就更加的简单了，它有固有的模式，一般先对结束条件进行判断，然后递归遍历各个子树，就这么简单。

对于本题DropDownItem的函数可以这样来写：

private ToolStripMenuItem Items(ToolStripMenuItem tsItem)

{   //结束条件判定

    if (tsItem.DropDownItems.Count <= 0) return tsItem;

    else

    {   //遍历各子树

        foreach (ToolStripMenuItem mItem in tsItem.DropDownItems)

        {   //递归遍历mItem子树

            Items(mItem);

        }

    }

    return null;

}

** 代码说明：**

函数首先判断节点(就是一个DropDownItem)是否含有子节点，如果它不含有子节点就return它(这就是结束条件判断)。

我们这样做完全是因为我们菜单使用习惯(所有的菜单功能都是在叶子节点实现功能的)，当然我们也可以将非叶子节点也return回去。但是最好不要这么干，因为它会令我们产生很多困扰(不信邪的朋友可以试试)。下一步再分别遍历该节点的每一个子树

上面是遍历某个DropDownItem和它的子节点，下面遍历整个菜单栏：

…… 

                //这是遍历菜单栏，可以放在任何你需要的地方，

                //注: menuStrip1是我菜单栏的名字

                foreach (ToolStripMenuItem mItem in this.menuStrip1.Items)

                {   //递归遍历各个DropDownItem

                    Items(mItem);

                }

                //

……

上面就是遍历菜单的全部代码。这当然还没完，我们需要将遍历菜单得到的各个菜单项存入容器，以备下面的程序使用。

什么容器都可以，而我选择了List<>。要实现这个功能：

1.首先，我们需要增加一个容器 lMenuItems

……

//增加一个全局变量，它是一个容器

List<ToolStripMenuItem> lMenuItems;

……

2.然后，在遍历菜单栏程序段中添加代码

//这是遍历菜单栏，可以放在任何你需要的地方，

                //menuStrip1是我菜单栏的名字

                lMenuItems = new List<ToolStripMenuItem>();

                foreach (ToolStripMenuItem mItem in this.menuStrip1.Items)

                {   //递归遍历各个DropDownItem

                    Items(mItem);

                }

                //

……

3.将DropDownItem的递归遍历函数修改成下面这个样子

private ToolStripMenuItem Items(ToolStripMenuItem tsItem)

        {   //结束条件判定

            if (tsItem.DropDownItems.Count <= 0) return tsItem;

            else

            {   //遍历各子树

                ToolStripMenuItem value = null;//临时变量

                foreach (ToolStripMenuItem mItem in tsItem.DropDownItems)

                {   //递归遍历mItem子树

                    value = Items(mItem);

                    if (value != null && lMenuItems != null)

                            lMenuItems.Add(value);

                }

            }

            return null;

        }

好，初战告捷。跳过如何提供用户的选择界面部分不提，直接进入重点。

为工具栏动态添Items及其事件

给工具栏动态添加Items其实是一件非常简单的事，就像有些人说的new一个，再Add()进去就搞定了。

关键的问题不在这里，如何使各个工具栏的Item的事件可以与DropDownItem的事件一一对应才是问题的关键。

各个DropDownItem都可以拥有自己的事件，各个事件的名称不同，而且事件是不能直接拿事件赋值的，如果无法实现事件的动态赋值，菜单栏动态添加也就没戏了。如果没有好多解决方法，程序开发到这里只能是僵局。

关于事件的调整

1.首先事件是可以调用事件的，并且几个控件可以共用一个事件。这就为问题的解决提供了可能性。
让所有的可用菜单项都使用一个事件，或者说让这个事件统领其他的菜单事件。
我们新建一个事件，并将这个事件命名为Menu_Click，它来统领整个Menu的所有Click事件：

1
2
3

private void Menu_Click(object sender, EventArgs e)

       { …… }

2.第二步，将原来所有DropDownItems的事件(菜单项事件)都替换成Menu_Click。

小知识：事件参数中的sender事实上就是发出事件的控件(或源)，但因为它的类型是object，所有在使用前要对其进行强制类型转换。

比如：有一个sender的实际类型是ToolStripItem，我需要获得sender的Name属性值就需要：

1	string sender_Name = ((ToolStripItem)sender).Name;

应用上面特点，在事件处理函数Menu_Click中就不难使用switch或者if/else来区分事件的来源，并分别调用他们自己的事件处理函数了。

3.动态添加

解决了事件的问题，工具栏的动态添加实际上就是一句话的事

toolStrip1.Items.Add(new ToolStripButton(

                                     <某DropDownItem>.Text, //DropDownItem显示的文字

                                     <某DropDownItem>.Image, //DropDownItem图标

                                     new System.EventHandler(Menu_Click), //DropDownItem事件

                                     <某DropDownItem>.Name //DropDownItem名称

));
