例

次の例は、このコンストラクターを使用して、コンテンツの範囲に適用される新しい Span を作成する方法を示しています。 コンテンツの範囲は、コンストラクターで指定された開始オブジェクトと終了 TextPointer オブジェクトによって決まります。

// Create a paragraph and three text runs to serve as example content.  
Paragraph parx = new Paragraph();
Run run1 = new Run("Text run 1.");
Run run2 = new Run("Text run 2.");
Run run3 = new Run("Text run 3.");

// Add the three text runs to the paragraph, separated by linebreaks.
parx.Inlines.Add(run1);
parx.Inlines.Add(new LineBreak());
parx.Inlines.Add(run2);
parx.Inlines.Add(new LineBreak());
parx.Inlines.Add(run3);

// After this line executes, the selection of content
// indicated by the "start" and "end" parameters will be
// enclosed by the new Span.  In this case, the new Span
// will enclose the entire contents of the Paragraph "parx",
// which happens to contain three text runs and two linebreaks.               
Span spanx = new Span(parx.ContentStart, parx.ContentEnd);

// Now, properties set on "spanx" will override default properties
// on elements contained by "spanx".  For example, setting 
// these arbitrary display properties on "spanx" will affect
// the child text runs enclosed by "spanx".
spanx.Foreground = Brushes.Blue;
spanx.Background = Brushes.GhostWhite;
spanx.FontFamily = new FontFamily("Century Gothic");

// Non-default property values override any settings on the 
// enclosing Span element.
run2.Foreground = Brushes.Red;
run2.Background = Brushes.AntiqueWhite;
run2.FontFamily = new FontFamily("Lucida Handwriting");

' Create a paragraph and three text runs to serve as example content.

parx3.Inlines.Add(New LineBreak())
parx3.Inlines.Add(run2)
