You can use HttpUtility HtmlDecode  If you are using  NET 4 0  you can also use WebUtility HtmlDecode which does not require an extra assembly reference as it is available in the System Net namespace

As  CQ says  you need to use HttpUtility HtmlDecode  but it s not available in a non-ASP  NET project by default   For a non-ASP  NET application  you need to add a reference to System Web dll   Right-click your project in Solution Explorer  select  Add Reference   then browse the list for System Web dll   Now that the reference is added  you should be able to access the method using the fully-qualified name System Web HttpUtility HtmlDecode or insert a using statement for System Web to make things easier
