WILT: XML encode a string in .net

Always wondered why I couldn’t find a method that would XML encode a string, effectively escaping the 5 illegal characters for XML. There is such a method but its location in the API is not intuitive at all. It’s in the System.Security namespace:

   1: public static string Escape(

   2:     string str

   3: )

Its usage is:

   1: tagText = System.Security.SecurityElement.Escape(tagText);

This will escape the 5 characters <, >, &, “ and ‘
