String Parsing in c# for http link
<p>Im trying to parse a string</p>

<p>{"Url":"<a href="http://repreeapi.cloudapp.net/PublicApi/" rel="nofollow">http://repreeapi.cloudapp.net/PublicApi/</a>{ActionName}/f23284d5-90a7-4c41-9bd4-8a47e64b4a75"}</p>

<p>I would just like to keep this part and save it as a new string:
<a href="http://repreeapi.cloudapp.net/PublicApi/" rel="nofollow">http://repreeapi.cloudapp.net/PublicApi/</a>{ActionName}/f23284d5-90a7-4c41-9bd4-8a47e64b4a75</p>

<p>And then I would like to replace {ActionName} with "launch"</p>

<p>so the final string should be </p>

<p><a href="http://repreeapi.cloudapp.net/PublicApi/launch/f23284d5-90a7-4c41-9bd4-8a47e64b4a75" rel="nofollow">http://repreeapi.cloudapp.net/PublicApi/launch/f23284d5-90a7-4c41-9bd4-8a47e64b4a75</a></p>

<p>I've tried using the split method but can't seem to get the result I want. Any help would be appreciated?</p>
