C# 如何在Windows应用程序中按名称动态创建ToolStripMenuItem？

表格2：

如何在表单上查找apProposToolStripMenuItem？我试图删除一个特定的

ToolStripMenuItem

，但它不起作用，我找不到

apProposToolStripMenuItem

表格1：

private ToolStripMenuItem mHelp;
private ToolStripMenuItem apProposToolStripMenuItem;
public void intializecomponent()
{
this.mHelp = new ToolStripMenuItem();
      this.contentsToolStripMenuItem = new ToolStripMenuItem();
      this.apProposToolStripMenuItem = new ToolStripMenuItem();
     this.mHelp.DropDownItems.AddRange(new ToolStripItem[2]
          {
            (ToolStripItem) this.contentsToolStripMenuItem,
            (ToolStripItem) this.apProposToolStripMenuItem
          });
          this.mHelp.Name = "mHelp";
          this.mHelp.Size = new Size(44, 20);
          this.mHelp.Text = "Help";
          this.contentsToolStripMenuItem.Name = "contentsToolStripMenuItem";
          this.contentsToolStripMenuItem.Size = new Size(122, 22);
          this.contentsToolStripMenuItem.Text = "Contents";
          this.contentsToolStripMenuItem.Click += new EventHandler(this.contentsToolStripMenuItem_Click);
          this.apProposToolStripMenuItem.Image = (Image) componentResourceManager.GetObject("apProposToolStripMenuItem.Image");
          this.apProposToolStripMenuItem.Name = "apProposToolStripMenuItem";
          this.apProposToolStripMenuItem.Size = new Size(122, 22);
          this.apProposToolStripMenuItem.Text = "About";
          this.apProposToolStripMenuItem.Click += new EventHandler(this.apProposToolStripMenuItem_Click);
    this.Load += new EventHandler(this.DocumentSpace_Load);
}

您可以按如下所示的名称将其删除：

ToolStripMenuItem mi = new ToolStripMenuItem("apProposToolStripMenuItem") { Name = "About" };
mi.DropDownItems.RemoveByKey("About");

mHelp.DropDownItems.RemoveByKey("apProposToolStripMenuItem");

您也可以直接将其删除，如下所示：

ToolStripMenuItem mi = new ToolStripMenuItem("apProposToolStripMenuItem") { Name = "About" };
mi.DropDownItems.RemoveByKey("About");

mHelp.DropDownItems.RemoveByKey("apProposToolStripMenuItem");

---

假设您可以访问表单上的

MenuStrip

或

ToolStrip

，则可以使用扩展方法查找所有项，而不管其在菜单层次结构中的位置及其父项。例如：

var about = mHelp.DropDownItems["apProposToolStripMenuItem"]
mHelp.DropDownItems.Remove(about);

谢谢兄弟。。但是mHelp是第二种形式，首先我在第一种形式中得到了mHelp如何？在你的代码中，

mHelp

是私有的。您必须将其公开，然后通过对

Form2

的引用访问它。
