推荐答案

你好，



我相信您可以在此处找到问题的解决方案：

如何在两个字符之间提取字符串 [ ^ ]



它使用一个正则表达式来查找字符串并将其解压缩。

Hi there,

I believe the solution to your problem can be found here:
How to extract the strings between two characters[^]

It uses a regular expression to find the string and extract it.

您好，



试试这个：

Hi,

Try this:

label1.Text = System.Text.RegularExpressions.Regex.Match(textBox1.Text, "(?<=#)(.+)(?=#)").Value
' change label1 and textBox1 into the names of your label and text box

希望这有帮助。

Hope this helps.
