[英]extract lines from a flowdocument in a richtextbox starting with specific words WPF
I'm very new to wpf and I would like to make a text analysing tool. 我是wpf的新手,我想制作一个文本分析工具。 I already know how to import text into rich textbox and format it properly, but now I want to run a method that extracts all lines in the flowdocument that start with INT or EXT and place them in a listbox.
我已经知道如何将文本导入到RTF文本框中并正确设置其格式,但是现在我想运行一种方法,该方法可提取FlowDocument中以INT或EXT开头的所有行并将它们放置在列表框中。 It seems to be quite easier to do this in winforms than in WPF.
在Winforms中执行此操作似乎比在WPF中容易得多。
Is there someone who can guide me with this? 有谁可以指导我吗?
I wish I could already provide some code but the flowdocument is new to me as is wpf. 我希望我已经可以提供一些代码,但是flowdocument和wpf对我来说都是新的。
I have written a code snippet to collect the lines that begin with INT or EXT. 我编写了一个代码段来收集以INT或EXT开头的行。 I am sure the code is not optimal, because i am not practised with RichTextBox, but i think it is very easy to understand.
我确定代码不是最佳的,因为我没有使用RichTextBox进行练习,但是我认为它很容易理解。
private List<string> CollectLines()
{
TextRange textRange = new TextRange(
// TextPointer to the start of content in the RichTextBox.
TestRichTextBox.Document.ContentStart,
// TextPointer to the end of content in the RichTextBox.
TestRichTextBox.Document.ContentEnd);
// The Text property on a TextRange object returns a string
// representing the plain text content of the TextRange.
var text = textRange.Text;
List<string> resultList = new List<string>();
// Collect all line that begin with INT or EXT
// Or use .Contains if the line could begin with a tab (\t), spacing or whatever
using (StringReader sr = new StringReader(text))
{
var line = sr.ReadLine();
while (line != null)
{
if (line.StartsWith("INT") || line.StartsWith("EXT"))
{
resultList.Add(line);
}
line = sr.ReadLine();
}
}
return resultList;
}
Maybe you can find out how you can put the list into a listbox yourself :) 也许您可以自己找到如何将列表放入列表框的方法:)
