@BjörnPollex You might be able to pull this of with decorator, but I'd expect you have to struggle with a lot of subtleties of the language. And even if you do you're still bound to use metaclass in one way or another since you don't want to use the default __repr__ to represent C.Python’s primitive data types include float, integer, Boolean, and string. The programming language provides several functions you can use to convert any of these data types to the other. One of those functions we’ll look at in this article is str(). It’s a built-in function you can use to convertIt then adds the property name as a key in the dictionary and, if a value exists, it adds the value, otherwise it adds null. public static Dictionary<string, object> ObjectToDictionary (object obj) { Dictionary<string, object> ret = new Dictionary<string, object> (); foreach (PropertyInfo prop in obj.GetType ().GetProperties ()) { string ...Two things: first, you cannot add to an existing class without modifying the class definition. If you have a class that you want convertible to std::string (or to double or whatever), you should define a conversion operator: in your case:A String object is a sequential collection of System.Char objects that represent a string; a System.Char object corresponds to a UTF-16 code unit. The value of the String object is the content of the sequential collection of System.Char objects, and that value is immutable (that is, it is read-only).2. Maven Dependency.
