範例

下列程式碼範例一開始會建立具有三 TabPage 個 TabControl 的 。 這個範例會 Remove 使用 方法來移除單一索引標籤頁面，特別是 tabPage2 從 tabControl1 控制項集合中移除。 請注意， TabPages 屬性會取得 tabControl1 控制項集合，以新增和移除此集合中的索引標籤頁面。

搭配此範例使用 System.Drawing 和 System.Windows.Forms 命名空間。

using namespace System::Drawing;
using namespace System::Windows::Forms;

public ref class Form1: public Form
{
private:
   TabControl^ tabControl1;
   TabPage^ tabPage1;
   TabPage^ tabPage2;
   TabPage^ tabPage3;

public:
   Form1()
   {
      this->tabControl1 = gcnew TabControl;
      array<System::String^>^tabText = {"tabPage1","tabPage2","tabPage3"};
      this->tabPage1 = gcnew TabPage( tabText[ 0 ]->ToString() );
      this->tabPage2 = gcnew TabPage( tabText[ 1 ]->ToString() );
      this->tabPage3 = gcnew TabPage( tabText[ 2 ]->ToString() );
      
      // Populates the tabControl1 with three tab pages.
      array<TabPage^>^tabPages = {tabPage1,tabPage2,tabPage3};
      this->tabControl1->TabPages->AddRange( tabPages );
      
      // Gets the tabControl1 controls collection.
      // Removes the tabPage2 from the collection.
      this->tabControl1->TabPages->Remove( tabPage2 );
      this->tabControl1->Location = Point(25,25);
      this->tabControl1->Size = System::Drawing::Size( 250, 250 );
      this->ClientSize = System::Drawing::Size( 300, 300 );
      this->Controls->Add( tabControl1 );
   }

};

{
   Application::Run( gcnew Form1 );
