命名空间:

System.Windows.Media

程序集:

PresentationCore.dll

设置 FormattedText 对象的字体样式。

重载

SetFontStyle(FontStyle)	设置 FormattedText 对象中整个字符集的字体样式。
SetFontStyle(FontStyle, Int32, Int32)	设置 FormattedText 对象中指定的字符子集的字体样式。

SetFontStyle(FontStyle)

设置 FormattedText 对象中整个字符集的字体样式。

public:
 void SetFontStyle(System::Windows::FontStyle style);

public void SetFontStyle (System.Windows.FontStyle style);

member this.SetFontStyle : System.Windows.FontStyle -> unit

Public Sub SetFontStyle (style As FontStyle)

参数

FontStyle

要用于设置文本格式的 FontStyle 值。

注解

FontStyle 支持类型转换行为，使类的 FontStyles 静态值可用于初始化 FontStyle 和填充类型 FontStyle参数。

此方法设置整个文本字符串的字体样式。 若要设置文本字符串子集的字体样式，请使用 SetFontStyle(FontStyle, Int32, Int32) 该方法。

SetFontStyle(FontStyle, Int32, Int32)

设置 FormattedText 对象中指定的字符子集的字体样式。

public:
 void SetFontStyle(System::Windows::FontStyle style, int startIndex, int count);

public void SetFontStyle (System.Windows.FontStyle style, int startIndex, int count);

member this.SetFontStyle : System.Windows.FontStyle * int * int -> unit

Public Sub SetFontStyle (style As FontStyle, startIndex As Integer, count As Integer)

参数

style

FontStyle

要用于设置文本格式的 FontStyle 值。

startIndex

Int32

要向其应用字体样式的初始字符的起始索引。

count

Int32

要向其应用字体样式的字符数。

示例

以下示例创建一个 FormattedText 对象，然后将多个格式样式应用于文本，包括 SetFontStyle。

protected override void OnRender(DrawingContext drawingContext)
{
    string testString = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor";

    // Create the initial formatted text string.
    FormattedText formattedText = new FormattedText(
        testString,
        CultureInfo.GetCultureInfo("en-us"),
        FlowDirection.LeftToRight,
        new Typeface("Verdana"),
        32,
        Brushes.Black);

    // Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300;
    formattedText.MaxTextHeight = 240;

    // Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    // The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5);

    // Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11);

    // Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(
                            new LinearGradientBrush(
                            Colors.Orange,
                            Colors.Teal,
                            90.0),
                            6, 11);

    // Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28);

    // Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, new Point(10, 0));
}

Protected Overrides Sub OnRender(ByVal drawingContext As DrawingContext)
    Dim testString As String = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor"

    ' Create the initial formatted text string.
    Dim formattedText As New FormattedText(testString, CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 32, Brushes.Black)

    ' Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
    formattedText.MaxTextWidth = 300
    formattedText.MaxTextHeight = 240

    ' Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
    ' The font size is calculated in terms of points -- not as device-independent pixels.
    formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5)

    ' Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
    formattedText.SetFontWeight(FontWeights.Bold, 6, 11)

    ' Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
    formattedText.SetForegroundBrush(New LinearGradientBrush(Colors.Orange, Colors.Teal, 90.0), 6, 11)

    ' Use an Italic font style beginning at the 28th character and continuing for 28 characters.
    formattedText.SetFontStyle(FontStyles.Italic, 28, 28)

    ' Draw the formatted text string to the DrawingContext of the control.
    drawingContext.DrawText(formattedText, New Point(10, 0))
End Sub
