下面的代码示例最初创建一个包含三个 TabPage 的 TabControl。本示例使用 Remove 方法来移除单个选项卡页，具体而言，是从 tabControl1 控件集合中移除 tabPage2。注意，TabPages 属性获取 tabControl1 控件集合以在此集合中添加和移除选项卡页。

对于此示例，使用 System.Drawing 和 System.Windows.Forms 命名空间。

Imports System.Drawing
Imports System.Windows.Forms

Public Class Form1
    Inherits Form
    Private tabControl1 As TabControl
    Private tabPage1 As TabPage
    Private tabPage2 As TabPage
    Private tabPage3 As TabPage

    Public Sub New()
        Me.tabControl1 = New TabControl()
        Dim tabText As String() = {"tabPage1", "tabPage2", "tabPage3"}
        Me.tabPage1 = New TabPage(tabText(0))
        Me.tabPage2 = New TabPage(tabText(1))
        Me.tabPage3 = New TabPage(tabText(2))

        ' Populates the tabControl1 with three tab pages.
        Me.tabControl1.TabPages.AddRange(New TabPage() {tabPage1, tabPage2, tabPage3})

        ' Gets the tabControl1 tab pages collection.
        ' Removes the tabPage2 from the collection.
        Me.tabControl1.TabPages.Remove(tabPage2)

        Me.tabControl1.Location = New Point(25, 25)
        Me.tabControl1.Size = New Size(250, 250)

        Me.ClientSize = New Size(300, 300)
        Me.Controls.Add(tabControl1)
    End Sub

    Shared Sub Main()
        Application.Run(New Form1())
    End Sub
End Class

    }

    static void Main()
