I just changed the internal to public and added this to the first parameter of each method, and then sorted the methods in the class in order of simplicity to difficulty. Perhaps because Typehelper is an internal class, and there is a strong application context, Typehelper does not use the way of contract programming, even in the name of some omitted: such as Isenumerabletype, GetElementType Two methods are actually used to ha

combination ... Perhaps a class is good to do, if we define a lot of classes, dozens of, hundreds of how to do? One by one implementing ToString (string format) would have worn people out.
