)
用法
Dim instance As ControlCollection
Dim value As Control

instance.Add(value)

public override void Add (
    Control value
)

public:
virtual void Add (
    Control^ value
) override

public void Add (
    Control value
)

public override function Add (
    value : Control
)

参数

  • value
    要添加到窗体中的 Control。

异常

异常类型 条件

Exception

不能向多文档界面 (MDI) 父窗体添加控件。

备注

可以使用此方法向窗体添加控件。如果要将一组已经创建的控件添加到窗体中，请使用 Control.ControlCollection 类的 Control.ControlCollection.AddRange 方法。

示例

下面的代码示例向窗体的控件集合添加一个 TextBox 控件和一个 Label 控件。该示例要求先创建一个名为 Form1 的窗体。

Public Sub AddMyControls()
    Dim textBox1 As New TextBox()
    Dim label1 As New Label()
    
    ' Initialize the controls and their bounds.
    label1.Text = "First Name"
    label1.Location = New Point(48, 48)
    label1.Size = New Size(104, 16)
    textBox1.Text = ""
    textBox1.Location = New Point(48, 64)
    textBox1.Size = New Size(104, 16)
    
    ' Add the TextBox control to the form's control collection.
    Controls.Add(textBox1)
    ' Add the Label control to the form's control collection.
    Controls.Add(label1)
End Sub 'AddMyControls

public void AddMyControls()
 {
    TextBox textBox1 = new TextBox();
    Label label1 = new Label();
    
    // Initialize the controls and their bounds.
    label1.Text = "First Name";
    label1.Location = new Point(48,48);
    label1.Size = new Size (104, 16);
    textBox1.Text = "";
    textBox1.Location = new Point(48, 64);
    textBox1.Size = new Size(104,16);
 
    // Add the TextBox control to the form's control collection.
    Controls.Add(textBox1);
    // Add the Label control to the form's control collection.
    Controls.Add(label1);
 }
 

public:
   void AddMyControls()
   {
      TextBox^ textBox1 = gcnew TextBox;
      Label^ label1 = gcnew Label;
      
      // Initialize the controls and their bounds.
      label1->Text = "First Name";
      label1->Location = Point( 48, 48 );
      label1->Size = System::Drawing::Size( 104, 16 );
      textBox1->Text = "";
      textBox1->Location = Point(48,64);
      textBox1->Size = System::Drawing::Size( 104, 16 );
      
      // Add the TextBox control to the form's control collection.
      Controls->Add( textBox1 );
      // Add the Label control to the form's control collection.
      Controls->Add( label1 );
   }
