示例

下面的示例演示如何使用 NextInline 属性。

// A host paragraph to hold the example Inline elements..
Paragraph par = new Paragraph();

// Some arbitrary Inline elements.
Run run1 = new Run("Text run number 1.");
Run run2 = new Run("Text run number 2.");
Bold bold = new Bold(new Run("Bold text."));
Italic ital = new Italic(new Run("Italic text."));
Span span1 = new Span(new Run("Span number 1"));
Span span2 = new Span(new Run("Span number 2"));

// Add the Inline elements to the Paragraph. Note the order
// of the inline elements in the paragraph; the order is 
// arbitrary, but the notion of an order is important with 
// respect to  what are 'previous' and 'next' elements.
par.Inlines.Add(run1);
par.Inlines.Add(run2);
par.Inlines.Add(bold);
par.Inlines.Add(ital);
par.Inlines.Add(span1);
par.Inlines.Add(span2);

' A host paragraph to hold the example Inline elements..
Dim par As New Paragraph()

' Some arbitrary Inline elements.
Dim run1 As New Run("Text run number 1.")
Dim run2 As New Run("Text run number 2.")
Dim bold As New Bold(New Run("Bold text."))
Dim ital As New Italic(New Run("Italic text."))
Dim span1 As New Span(New Run("Span number 1"))
Dim span2 As New Span(New Run("Span number 2"))

' Add the Inline elements to the Paragraph. Note the order
' of the inline elements in the paragraph; the order is 
' arbitrary, but the notion of an order is important with 
' respect to  what are 'previous' and 'next' elements.
par.Inlines.Add(run1)
par.Inlines.Add(run2)
par.Inlines.Add(bold)
par.Inlines.Add(ital)
par.Inlines.Add(span1)
par.Inlines.Add(span2)

// After this line executes, "previousSibling" is null, since "run1" is
// the first Inline element in the Paragraph.
Inline previousSibling = run1.PreviousInline;

// After this line executes, "previousSibling" holds "bold", which is the
// first peer-level Inline preceeding "ital".
previousSibling = ital.PreviousInline;

// After this line executes, "previousSibling" holds "span1", which is the
// first peer-level Inline preceeding "span1".
previousSibling = span2.NextInline;

' After this line executes, "previousSibling" is null, since "run1" is
' the first Inline element in the Paragraph.
Dim previousSibling As Inline = run1.PreviousInline

' After this line executes, "previousSibling" holds "bold", which is the
' first peer-level Inline preceeding "ital".
previousSibling = ital.PreviousInline

' After this line executes, "previousSibling" holds "span1", which is the
' first peer-level Inline preceeding "span1".
previousSibling = span2.NextInline
