这类似于:How to add things to a menustrip programatically?,但我需要稍微不同的东西。
我有一个winform,我正在创建表单的新实例。但是,当我创建一个新表格时,我还会收集表单的所有当前实例,并填充一个" Window"带有menuitems的菜单让我关闭窗户。因此,我不仅需要以编程方式向menustrip添加内容,还需要指定这些菜单的功能。这可能吗?
代码:
private void newWindowToolStripMenuItem_Click(object sender, EventArgs e)
{
var newForm = new Form1();
newForm.Show();
foreach (Form form in Application.OpenForms)
{
// add menu items under "Window" with the name of the window and the
// event handler to close that window, aka form.Close() I assume;
}
}
我想这样做,以便我更新" Window"菜单每次我创建一个新窗口,以便我关闭的窗口列表是准确的,没有任何奇怪的额外的东西。

您可以创建包含必填字段的类,并传递所需的数据。
public class MenuItemInfo
{
public string Text { get; set; }
public object Tag { get; set; }
public EventHandler Handler { get; set; }
}
var menuItems = new List<MenuItemInfo>
{
new MenuItemInfo
{
Text = "whatever",
Tag = whatever,
Handler = (o, s) =>
{
//Do whatever
}
}
};
ToolStripMenuItem toolStripMenuItem;
foreach (var mi in menuItems)
{
ToolStripMenuItem foo = new ToolStripMenuItem(mi.Text);
foo.Click += mi.Handler;
foo.Tag = mi.Tag;
toolStripMenuItem.DropDownItems.Add(foo);
}

将“ItemClicked” - 事件添加到ContexMenuStrip菜单中。 “ContextMenuStrip1”是此处使用的菜单的名称。编辑部分代码如下:
var newForm = new Form1() { Name = "myForm" };
newForm.Show();
foreach (Form form in Application.OpenForms)
{
// Add new menuitem with the name of the form, and save the reference to "Tag"-property
ToolStripMenuItem newItem = new ToolStripMenuItem() { Name = newForm.Name, Text = newForm.Name, Tag = newForm };
// Add the new item to the menu
contextMenuStrip1.Items.Add(newItem);
}
然后点击“ItemClicked” -event:
private void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
// Close the linked form, if it isn't disposed
if (!((Form)((ToolStripItem)e.ClickedItem).Tag).IsDisposed)
{
((Form)((ToolStripItem)e.ClickedItem).Tag).Close();
}
// Remove this menuitem from the menu
contextMenuStrip1.Items.Remove((ToolStripItem)e.ClickedItem);
}
