推荐答案

使用此正则表达式，确保未打开Multiline选项：

Use this regex, making sure that the Multiline option is NOT turned on:

\n=+\nOne

在默认模式下，您可以将换行符与 \ n 并继续从一行到下一行匹配。所以我的正则表达式寻找换行符后跟所有=直到另一个换行符，然后单词One。

In the default mode, you can match newlines with \n and continue matching from one line to the next. So my regex looks for a newline followed by all "=" until another newline, then the word "One".

如果你的模式没有改变，你可以使用 String.Substring方法 [ ^ ]和 String.LastIndexOf方法 [ ^ ]找到它。

对于Ex - 假设上面的字符串存储在变量str中。使用上面的方法你可以编写类似

If your patter doesn't change, you can use combination of String.Substring Method[^] and String.LastIndexOf Method[^] to find it.
For Ex - suppose the above string is stored in a variable str. Using above methods you could write something like

str.Substring(str.LastIndexOf("==="), str.IndexOf(" ") + 1);

请注意，这只是一个例子。虽然它会为您的问题提供正确的输出，但您必须根据您的要求进行微调（例如，如果您有2位或更多位数字）。



希望这给了你一个想法。

Please note that this is just an example. Though it will give a correct output for your question, you must fine tune it based on your requirement (for ex if you have 2 or more digit numbers).

Hope this gives you an idea.
