I need to parse a sentence. If I find a hash in the sentence, I would like to bold it.
Example : Bonjour #hello Hi => Bonjour #hello Hi

Seems like a good situation for regex
I'd do something like this
boldHashes("Bonjour #hello Hi");
...
private string boldHashes(string str)
{
return Regex.Replace(str, @"(#\w+)", "<strong>$1</strong>");
}
In this case we're matching a literal hash # plus a word of any length \w+ and group it between () so we can use the $1 substitions in the Regex.Replace function
Updated jQuery doing the same thing.
Something like:
HTML
<div id="myDiv">Bonjour #Hello hi</div>
jQuery
$('#myDiv').html($('#myDiv').text().replace(/(#\w+)/g, '<strong>$1</strong>'));
There's probably a more elegant way to do this but you can use the String.IndexOf method to find the first instance of the hash like so
String myString = "Bonjour #hello hi";
int index = myString.IndexOf('#');
if(index>-1) //IndexOf returns -1 if the character isn't found
{
//search for the next space after the hash
int endIndex=mystring.IndexOf(' ',index+1)
myString=MakeBold(myString,index,endIndex);
}
All that's left for you is to implement the MakeBold function.

also, you probably want to extend the function to take into account multiple hashes in the string.
