In your example, you could add a static property (or method) that provides you with the info you want. Something like: class Foo { public static string ClassName { get { return MethodBase.GetCurrentMethod ().DeclaringType.Name; } } }The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.. Strings are constant; their values cannot be changed after they are created.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:Strings are useful for holding data that can be represented in text form. Some of the most-used operations on strings are to check their length, to build and concatenate them using the + and += string operators, checking for the existence or location of substrings with the indexOf() method, or extracting substrings with the substring() method.String toString () is the built-in method of java.lang which return itself a string. So here no actual conversion is performed.
