ListViewItem.ListViewSubItem.Font 属性

获取或设置子项显示的文本的字体。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
<LocalizableAttribute(True)> _
Public Property Font As Font
用法
Dim instance As ListViewSubItem
Dim value As Font

value = instance.Font

instance.Font = value

[LocalizableAttribute(true)] 
public Font Font { get; set; }

[LocalizableAttribute(true)] 
public:
property Font^ Font {
    Font^ get ();
    void set (Font^ value);
}

/** @property */
public Font get_Font ()

/** @property */
public void set_Font (Font value)

public function get Font () : Font

public function set Font (value : Font)

属性值

要应用于由控件显示的文本的 Font。

备注

您可以使用此属性来更改应用于子项文本的字体样式。如果 ListViewItem 的 UseItemStyleForSubItems 属性设置为 true，则更改此属性不会有任何效果。由于 Font 不可变（意即您无法调整其任何属性），所以您只能为 Font 属性分配一个新的 Font。但是，可以使新的字体基于现有字体。

以下是如何调整现有字体以使其成为粗体的示例：

listViewItem1.SubItems[1].Font = new Font(listViewItem1.SubItems[1].Font, 
       listViewItem1.SubItems[1].Font.Style | FontStyle.Bold);

ListViewItem1.SubItems[1].Font = New Font(ListViewItem1.SubItems[1].Font, _ 
       ListViewItem1.SubItems[1].Font.Style Or FontStyle.Bold)

如果拥有该子项的 ListViewItem 的 UseItemStyleForSubItems 属性设置为 true，则设置该属性不会有任何效果。

示例

下面的代码示例演示了如何将 UseItemStyleForSubItems 属性设置为 false，以便为 ListViewItem.ListViewSubItem 对象定义自定义样式。该示例演示如何设置 ForeColor 和 Font 属性。若要运行此示例，请将以下代码粘贴到一个窗体中，并从该窗体的构造函数或 Load 事件处理方法中调用 InitializeListView 方法。
