Reading in lines of text from a rich text box
提问by user3494110
I am making a small application for myself that concatenates some statements based on text that is entered into a couple rich text boxes on a form.
我正在为自己制作一个小应用程序，它根据输入到表单上几个富文本框中的文本连接一些语句。
One text box may have 10-20 lines of text, and each line is it its own separate entry, so I need to be able to read the text line-by-line.
一个文本框可能有 10-20 行文本，每一行都是它自己单独的条目，所以我需要能够逐行阅读文本。
However, when researching WPFs, I have only seen one statement on the net in regards to reading text and it is reading the content of the box from start to finish. I would like to somehow loop through it or separate it line-by-line.
但是，在研究WPF时，我只在网上看到过一种关于阅读文本的说法，它是从头到尾阅读框的内容。我想以某种方式循环遍历它或将其逐行分开。
According to MSDN, to extract text from a WPF rich text box into a string, you need to use:
根据 MSDN，要将 WPF 富文本框中的文本提取为字符串，您需要使用：
string StringFromRichTextBox(RichTextBox rtb)
{
TextRange textRange = new TextRange(
// TextPointer to the start of content in the RichTextBox.
rtb.Document.ContentStart,
// TextPointer to the end of content in the RichTextBox.
rtb.Document.ContentEnd
);
// The Text property on a TextRange object returns a string
// representing the plain text content of the TextRange.
return textRange.Text;
}
However, if you were to look at my rich text box, you would see that the text inside is a list of values, so for instance, one box may look like below:
但是，如果您查看我的富文本框，您会看到里面的文本是一个值列表，例如，一个框可能如下所示：
000423523
324
93489290099
823342342
0003242342
44400298889
I want to be able to read those values line by line within the RichTextBox, but in WPF, there doesn't seem to be a richtextbox1.Linesoption.
我希望能够在 中逐行读取这些值RichTextBox，但在 WPF 中，似乎没有richtextbox1.Lines选项。

You can use String.Split()method to split RichTextBoxtext by line-break and exclude empty lines from result set, for example :
您可以使用String.Split()方法RichTextBox按换行符拆分文本并从结果集中排除空行，例如：
String[] lines =
StringFromRichTextBox(rtb).Split(new[]{Environment.NewLine}
, StringSplitOptions.RemoveEmptyEntries);
foreach (var line in lines)
{
MessageBox.Show(line);
}

To read lines of a WPF RichTextBox you can use the following code.
要读取 WPF RichTextBox 的行，您可以使用以下代码。
TextRange textRange = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd);
string[] rtbLines = textRange.Text.Split(Environment.NewLine);
foreach(line in rtbLines)
{
//do something with line
}
for this specific code, you will need to use the following library
对于此特定代码，您将需要使用以下库
using System.Windows.Documents;

Sorry for brevity, but how about something as simple as
抱歉为简洁，但像这样简单的事情怎么样？
var lines = richTextBox1.Text.Split('\n');
