WPF中的RichTextBox - 获取最后一个文本块

Question

Could anybody share the idea how to get the last block of a RichTextBox 's document in WPF? I tried with code:

Block pg = box.Document.ContentEnd.Paragraph.PreviousBlock;
box.Document.Blocks.Remove(pg);

But it doesn't work (the first line is throwing exceptions).

Answer 1

我认为这必须对你有所帮助：

box.Document.Blocks.Remove(box.Document.Blocks.LastBlock)
