Dynamic languages have been developing very quickly this year, with a variety of scripting languages with a number of dynamic language features. Dynamic language has won the favor of many people with its flexible syntax and rich run-time behavior. In the. NET Camp, C # has been playing the role of static language, although 3.0 of the syntax changes are radical, but still focus on compile-time type checking and constraints. The use of the dynamic characteristics of the bad will produce more run-t

This section introduces two new features of VB9 as an auxiliary feature for data development. CLR adds many new features about delegation in. NET 2.0 (but most of them are not supported by any language ).CovariantThis feature allows you to relax the signature check when the delegate is bound to the function (supported by C #2.0 ). In order to pursue higher flexibility, VB9 decided to introduceLoose Delegation. Specify a function for the delegated instance according to the following rules: 1. The

When talking about the differences between dynamic and Static languages, there is a classic saying: Static typing when possible, dynamic typing when needed. Visual Basic supports post-binding and dynamic identifiers. Therefore, you can perform operations based on the object runtime type. Only later binding or dynamic identifiers do not have constraints on the type of parameters or return values. They only o

Visual Basic 9.0 supports the query function integrated with the next generation of languages, and supports relational queries on DLinq data objects or XLinq XML data, these queries are implemented by using a group of methods (or operators) on DLinq or XLinq related objects. VB9 developers think that this query method should also be used to organize existing object data, such as IEnumerable and other sets.
