Control.Font Control.Font Control.Font Control.Font Property

定義

取得或設定控制項顯示之文字字型。Gets or sets the font of the text displayed by the control.

public:
 virtual property System::Drawing::Font ^ Font { System::Drawing::Font ^ get(); void set(System::Drawing::Font ^ value); };
public virtual System.Drawing.Font Font { get; set; }
member this.Font : System.Drawing.Font with get, set
Public Overridable Property Font As Font

屬性值

要套用至控制項顯示之文字的 FontThe Font to apply to the text displayed by the control. 預設值為 DefaultFont 屬性的值。The default is the value of the DefaultFont property.

範例

下列程式碼範例會顯示FontDialog給使用者,並變更FontDateTimePicker控制項。The following code example displays a FontDialog to the user and changes the Font of a DateTimePicker control. 此範例中,您需要Form具有ButtonDateTimePicker在其上。This example requires that you have a Form with Button and a DateTimePicker on it.

private:
   void myButton_Click( Object^ sender, EventArgs^ e )
   {
      FontDialog^ myFontDialog = gcnew FontDialog;
      if ( myFontDialog->ShowDialog() == ::DialogResult::OK )
      {
         // Set the control's font.
         myDateTimePicker->Font = myFontDialog->Font;
      }
   }
private void myButton_Click(object sender, EventArgs e)
{
   FontDialog myFontDialog = new FontDialog();
   if(myFontDialog.ShowDialog() == DialogResult.OK)
   {
      // Set the control's font.
      myDateTimePicker.Font = myFontDialog.Font;
   }
}
Private Sub myButton_Click(sender As Object, e As EventArgs)
   Dim myFontDialog As FontDialog
   myFontDialog = New FontDialog()
   
   If myFontDialog.ShowDialog() = DialogResult.OK Then
      ' Set the control's font.
      myDateTimePicker.Font = myFontDialog.Font
   End If
End Sub

備註

Font屬性是環境的屬性。The Font property is an ambient property. 環境屬性是控制項屬性,如果未設定,將擷取從父控制項。An ambient property is a control property that, if not set, is retrieved from the parent control. 例如,Button具有相同BackColor做為其父系Form預設。For example, a Button will have the same BackColor as its parent Form by default. 如需有關環境屬性的詳細資訊,請參閱AmbientProperties類別或Control類別概觀。For more information about ambient properties, see the AmbientProperties class or the Control class overview.

因為Font不可變 (表示您無法調整其任一屬性),您只能指派Font新的屬性FontBecause the Font is immutable (meaning that you cannot adjust any of its properties), you can only assign the Font property a new Font. 不過,您可以根據現有的字型為新字型。However, you can base the new font on the existing font.

[Visual Basic 中, C#][Visual Basic, C#]

如何調整現有的字型,讓它變成粗體的範例如下:The following is an example of how to adjust the existing font to make it bold:

myControl.Font = new Font(myControl.Font,   
    myControl.Font.Style | FontStyle.Bold);  
MyControl.Font = New Font(MyControl.Font, _   
    MyControl.Font.Style Or FontStyle.Bold)  

給繼承者的注意事項

當覆寫Font屬性在衍生類別中,使用基底類別的Font擴充的基底實作的屬性。When overriding the Font property in a derived class, use the base class's Font property to extend the base implementation. 否則,您必須提供所有的實作。Otherwise, you must provide all the implementation. 您不需要覆寫兩個getset存取子Font屬性; 您可以覆寫只能有一個如有需要。You are not required to override both the get and set accessors of the Font property; you can override only one if needed.
