示例1: GetSelectionOffsetsRTB
struct SelectionOffsets { internal int Start; internal int End; }
SelectionOffsets GetSelectionOffsetsRTB(RichTextBox richTextBox)
{
SelectionOffsets selectionOffsets;
TextPointer contentStart = richTextBox.Document.ContentStart;
// Find the offset for the starting and ending TextPointers.
selectionOffsets.Start = contentStart.GetOffsetToPosition(richTextBox.Selection.Start);
selectionOffsets.End = contentStart.GetOffsetToPosition(richTextBox.Selection.End);
return selectionOffsets;
}
void RestoreSelectionOffsetsRTB(RichTextBox richTextBox, SelectionOffsets selectionOffsets)
{
TextPointer contentStart = richTextBox.Document.ContentStart;
// Use previously determined offsets to create corresponding TextPointers,
// and use these to restore the selection.
richTextBox.Selection.Select(
contentStart.GetPositionAtOffset(selectionOffsets.Start),
contentStart.GetPositionAtOffset(selectionOffsets.End)
);
