Public Overridable Property Font As Font

属性值

要应用于由控件显示的文本的 FontThe Font to apply to the text displayed by the control. 默认为 DefaultFont 属性的值。The default is the value of the DefaultFont property.

示例

下面的代码示例显示FontDialog给用户,并更改FontDateTimePicker控件。The following code example displays a FontDialog to the user and changes the Font of a DateTimePicker control. 此示例要求具有FormButton和一个DateTimePicker上它。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

注解

Font属性是一个环境属性。The Font property is an ambient property. 环境属性是控件属性,如果未设置,检索从父控件。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作为其父Form默认情况下。For example, a Button will have the same BackColor as its parent Form by default. 有关环境属性的详细信息,请参阅AmbientProperties类或Control类概述。For more information about ambient properties, see the AmbientProperties class or the Control class overview.

因为Font是不可变的 (这意味着您不能调整其任何属性),您可以只分配Font属性指定新FontBecause the Font is immutable (meaning that you cannot adjust any of its properties), you can only assign the Font property a new Font. 但是,您可以基于现有字体中的新字体。However, you can base the new font on the existing font.

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

以下是如何调整现有字体以粗体显示的示例: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)  

继承者说明

重写时Font属性在派生类中,使用基类的Font属性扩展的基实现。When overriding the Font property in a derived class, use the base class's Font property to extend the base implementation. 否则,必须提供所有的实现。Otherwise, you must provide all the implementation. 不需要重写二者getset访问器Font属性; 您可以根据需要覆盖只有一个。You are not required to override both the get and set accessors of the Font property; you can override only one if needed.
