in this case. IMG标签仅在某些情况下提供,我想提取链接,即在这种情况下http://imgur.com/a/bwBpM
。 Is there an easy way to do this through regex in C#? 有没有一种简单的方法可以通过C#中的正则表达式来实现这一点?
If you're saying that you have the text in the question in some kind of list and they are always either in the format of: 如果你说你在某个列表中有问题中的文字,它们总是采用以下格式:
then the easiest thing to do is to run: 然后最简单的方法是运行:
url = url.Replace("[IMG]", "").Replace("[/IMG]");
if there are no tags then there is no change, but if the tags are there they will be stripped out. 如果没有标签,那么没有变化,但如果标签在那里,它们将被剥离。
You could use this pattern: 你可以使用这种模式:
^(?:\[IMG\])?([^[]*)(?:\[/IMG\])?$
You can get the output using: 您可以使用以下方式获取输出:
var match = Regex.Match(input, @"^(?:\[IMG\])?([^[]*)(?:\[/IMG\])?$");
if (match.Success)
{
Console.WriteLine(match.Groups[1].Value); // http://imgur.com/a/bwBpM
