What is a namespace in Visual Basic?
What is a namespace in Visual Basic?
Namespaces organize the objects defined in an assembly. Assemblies can contain multiple namespaces, which can in turn contain other namespaces. Namespaces prevent ambiguity and simplify references when using large groups of objects such as class libraries.
Is namespace and class the same?
Classes are data types. They are an expanded concept of structures, they can contain data members, but they can also contain functions as members whereas a namespace is simply an abstract way of grouping items together.
What two types of namespaces are there?
When creating a namespace, you must choose one of two namespace types: a stand-alone namespace or a domain-based namespace. In addition, if you choose a domain-based namespace, you must choose a namespace mode: Windows 2000 Server mode or Windows Server 2008 mode.
What are namespaces and classes?
Difference between namespace and class in C++ The namespace and classes are two different concepts. Classes are datatypes. Classes can contain data members and functions as members, but namespaces can contain variables and functions by grouping them into one. The namespaces cannot be created as objects.
What is namespace explain in detail?
A namespace is a declarative region that provides a scope to the identifiers (the names of types, functions, variables, etc) inside it. Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially when your code base includes multiple libraries.
Why do we use namespace?
Namespaces allow us to group named entities that otherwise would have global scope into narrower scopes, giving them namespace scope. This allows organizing the elements of programs into different logical scopes referred to by names. Namespace is a feature added in C++ and not present in C.
How many classes are in a namespace?
Two classes with the same name can be created inside 2 different namespaces in a single program. Inside a namespace, no two classes can have the same name. In C#, the full name of the class starts from its namespace name followed by dot(.)
Are type and class the same?
Types generally represent nouns, such as a person, place or thing, or something nominalized, A class represents an implementation of the type. Different concrete classes can produce objects of the same abstract type (depending on type system). Similarly, a given class may have several different constructors.
