C# - 将 MenuStrip 代码转换为 ToolStrip

我正在尝试将最初用于 MenuStrip 的代码转换为可用于 ToolStrip 的代码。简而言之，MenuItem 被传递给 Init()，我需要确定相关菜单项的父项是什么。此代码片段可以与 MenuStrip 配合使用，但我似乎无法将其与父级为 ToolStripDropDownButton 的 ToolStrip 配合使用。

原始代码片段（MenuStrip的理想选择）：

private MenuItem menuItemMRU;
private MenuItem menuItemParent;

public void Init(MenuItem mruItem)
{
    menuItemMRU = mruItem;
    menuItemParent = (MenuItem) menuItemMRU.Parent;
}

这是我到目前为止所得到的

private ToolSTripMenuItem menuItemMRU;
private ToolStripDropDownButton menuItemParent;

public void Init(ToolStripMenuItem mruItem)
{
    menuItemMRU = mruItem;
    menuItemParent = (ToolStripMenuItem)menuItemMRU.Owner;
}

这给了我以下错误：

无法将类型“System.Windows.Forms.ToolStrip”转换为“System.Windows.Forms.ToolStripMenuItem”

原文

I am trying to convert code that was originally meant for a MenuStrip to something that will work with a ToolStrip. In short, a MenuItem is passed on to Init() and I need to determine what the parent is of the menu item in question. This snippet works fine with a MenuStrip, but I can't seem to get it working with a ToolStrip where the parent is a ToolStripDropDownButton.

Original Code Snippet (Ideal for MenuStrip):

private MenuItem menuItemMRU;
private MenuItem menuItemParent;

public void Init(MenuItem mruItem)
{
    menuItemMRU = mruItem;
    menuItemParent = (MenuItem) menuItemMRU.Parent;
}

This is what I've got so far

private ToolSTripMenuItem menuItemMRU;
private ToolStripDropDownButton menuItemParent;

public void Init(ToolStripMenuItem mruItem)
{
    menuItemMRU = mruItem;
    menuItemParent = (ToolStripMenuItem)menuItemMRU.Owner;
}

This gives me the following error:

Cannot convert type 'System.Windows.Forms.ToolStrip' to 'System.Windows.Forms.ToolStripMenuItem'
