我使用MenuStrip作为战斗中的动作命令为我和我的家人制作一个小游戏。但是，我无法弄清楚如何为魔术设置Click功能。因为menustrip大部分是空白的，所以我不能创建法术和目标列表，并为这些法术设置点击方法。我有点陷入僵局......

我认为您应该开始将代码划分为子类。即使是小游戏，它也会非常有用。这是我拼凑的一些代码。它不能处理您拥有的所有内容，但您可以轻松扩展该功能。如果您需要其他信息，请告诉我。

foreach (BasicSpell spell in m_lstSpells)

if (spell.CanHitAllEnemies)
{
ToolStripItem tsiAll = tsmiSpell.DropDownItems.Add("All");
tsiAll.Click += (sender, arguments) => m_lstTargets.ForEach((target) => TryCastSpell(spell, target));
