private void Form1_Load(object sender, System.EventArgs e)
{
    System.Windows.Forms.ToolTip ToolTip1 = new System.Windows.Forms.ToolTip();
    ToolTip1.SetToolTip(this.textBox1, "Hello");
}

如何：创建快捷菜单并将其附加到控件

private void Form1_Load(object sender, System.EventArgs e)
{
    System.Windows.Forms.ContextMenu contextMenu1;
    contextMenu1 = new System.Windows.Forms.ContextMenu();
    System.Windows.Forms.MenuItem menuItem1;
    menuItem1 = new System.Windows.Forms.MenuItem();
    System.Windows.Forms.MenuItem menuItem2;
    menuItem2 = new System.Windows.Forms.MenuItem();
    System.Windows.Forms.MenuItem menuItem3;
    menuItem3 = new System.Windows.Forms.MenuItem();

    contextMenu1.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {menuItem1, menuItem2, menuItem3});
    menuItem1.Index = 0;
    menuItem1.Text = "MenuItem1";
    menuItem2.Index = 1;
    menuItem2.Text = "MenuItem2";
    menuItem3.Index = 2;
    menuItem3.Text = "MenuItem3";

    textBox1.ContextMenu = contextMenu1;
}

如何：在运行时添加 Windows 窗体控件

private void Form1_Load(object sender, System.EventArgs e)
{
    TextBox MyTextBox = new System.Windows.Forms.TextBox();
    MyTextBox.Location = new System.Drawing.Point(64, 40);
    MyTextBox.Name = "MyTextBox";
    MyTextBox.Size = new System.Drawing.Size(88, 21);
    MyTextBox.TabIndex = 0;
    MyTextBox.Text = "MyTextBox";
    Controls.Add(MyTextBox);

    MyTextBox.DoubleClick += new EventHandler(MyTextBox_DoubleClick);
}
private void MyTextBox_DoubleClick(object sender, System.EventArgs e)
{
    MessageBox.Show("MyTextBox doubleClick event.");
}
