Question: I'm trying to remove all BBCode Tags from a string.

```
[url]www.google.com[/url]

```

becomes

```
www.google.com

```

I have a regex that works in php to find them all, just dont know how to remove them in .net

RegEx to Find BBCode

```
|[[\/\!]*?[^\[\]]*?]|si

```

Answer: 
Your regular expression looks like it won't work so I tried a different one:

```
string s = "[url]www.google.com[/url] [url=www.google.com]www.google.com[/url]";
s = Regex.Replace(s, @"\[[^]]+\]", "");

```

Result:

```
www.google.com www.google.com

```

Also, you will need this using statement at the top of your file to make this work:

```
using System.Text.RegularExpressions;

```
I you use *Codekicker.BBCode* library ([this](https://www.nuget.org/packages/CodeKicker.BBCode/) or [that](https://www.nuget.org/packages/BBCode/)) then this code will strip known bbcode tags:

```
parser.ParseSyntaxTree(@"[url]www.google.com[/url] [url=www.google.com]www.google.com[/url]").ToText()

```

This will strip only known BB code tags and you need to first create `BBCodeParser` instance with information about used tags. The default parser used by library is:

```
var parser = new BBCodeParser(ErrorMode.ErrorFree, null, new[]
{
    new BBTag("b", "<b>", "</b>"),
    new BBTag("i", "<span style=\"font-style:italic;\">", "</span>"),
    new BBTag("u", "<span style=\"text-decoration:underline;\">", "</span>"),
    new BBTag("code", "<pre class=\"prettyprint\">", "</pre>"),
    new BBTag("img", "<img src=\"${content}\" />", "", false, true),
    new BBTag("quote", "<blockquote>", "</blockquote>"),
    new BBTag("list", "<ul>", "</ul>"),
    new BBTag("*", "<li>", "</li>", true, false),
    new BBTag("url", "<a href=\"${href}\">", "</a>", new BBAttribute("href", ""), new BBAttribute("href", "href")),
});

```

(you need to create it yourself, *Codekicker.BBCode* doesn't expose this object)
