成为RichTextBox和Googling的新手几个小时,我很难过。已经隔离了流程文档的段落部分。我现在希望删除所有文本,包括段落中的第一个“:” - 但保留段落的其余部分(包括其所有格式--XAML)。 (这在WPF vs2010中)。
我确定它很简单,但这是怎么做到的?
到目前为止,我将阅读第一个“:”,但您如何删除此文本?还有更好的方法吗?
public InkRichViewModel(int p, Paragraph paragraph)
{
this.p = p;
//Read the paragraph title from the paragraph
TextPointer start = paragraph.ContentStart;
TextPointer end = FindWordFromPosition(start, ":");
TextRange textRange = new TextRange(start, end);
String Title = textRange.Text;
//Remove the title from the paragraph
TextPointer endp = paragraph.ContentEnd;
TextRange t2 = new TextRange(start, endp);
?????????????????????????????????????????
this.Note = paragraph; <---Note is the paragraph without the leading string.
}
感谢所有帮助,问候。

就我而言,这解决了上述问题。还有更好的方法吗?
// Read paragraph upto and including first ":"
string text = (paragraph.Inlines.FirstInline as Run).Text;
int r = text.IndexOf(":")+1;
string Title = text.Substring(0,r).Trim();
// Remove Title from text;
string newtext = text.Substring(r).Trim();
// Insert new inline and remove the old inline.
Inline z = paragraph.Inlines.FirstInline;
Run runx = new Run(newtext);
paragraph.Inlines.InsertBefore(z, runx);
paragraph.Inlines.Remove(z);
this.Note = paragraph;
