示例1: GetOffsetRelativeToParagraph
// Returns the offset for the specified position relative to any containing paragraph.
int GetOffsetRelativeToParagraph(TextPointer position)
{
// Adjust the pointer to the closest forward insertion position, and look for any
// containing paragraph.
Paragraph paragraph = (position.GetInsertionPosition(LogicalDirection.Forward)).Paragraph;
// Some positions may be not within any Paragraph;
// this method returns an offset of -1 to indicate this condition.
return (paragraph == null) ? -1 : paragraph.ContentStart.GetOffsetToPosition(position);
}
// Returns a TextPointer to a specified offset into a specified paragraph.
TextPointer GetTextPointerRelativeToParagraph(Paragraph paragraph, int offsetRelativeToParagraph)
{
// Verify that the specified offset falls within the specified paragraph. If the offset is
// past the end of the paragraph, return a pointer to the farthest offset position in the paragraph.
// Otherwise, return a TextPointer to the specified offset in the specified paragraph.
return (offsetRelativeToParagraph > paragraph.ContentStart.GetOffsetToPosition(paragraph.ContentEnd))
? paragraph.ContentEnd : paragraph.ContentStart.GetPositionAtOffset(offsetRelativeToParagraph);
