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

Question

表格 2:

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);
}

如何在窗体上找到apProposToolStripMenuItem？我试图删除特定的 ToolStripMenuItem，但它不起作用，而且我找不到 apProposToolStripMenuItem。

表格 1:

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

Answer 1

您可以像这样通过名称删除它:

mHelp.DropDownItems.RemoveByKey("apProposToolStripMenuItem");

你也可以像这样直接删除它:

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