Namespace is a feature added in C++ and not present in C. A namespace is a declarative region that provides a scope to the identifiers (names of the types, function, variables etc) inside it. Multiple namespace blocks with the same name are allowed. All declarations within those blocks are declared in the named scope.

Why namespace is used in C#?

Namespaces are used to provide a “named space” in which your application resides. They’re used especially to provide the C# compiler a context for all the named information in your program, such as variable names. Without namespaces, for example, you wouldn’t be able to make a class named Console, as .

What is the difference between class and namespace?

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. Using a class implies that you can create an instance of that class, not true with namespaces.

Can you have more than one namespace in C#?

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(.)

What is a method in C#?

A method is a code block that contains a series of statements. A program causes the statements to be executed by calling the method and specifying any required method arguments. In C#, every executed instruction is performed in the context of a method. This article discusses named methods.

What is the difference between class and method in C#?

A class consists of member variables, functions, properties etc. A method is a block of code in C# programming. The function makes program modular and easy to understand. In object oriented programming, classes and methods are the essential thing.

What is namespace example?

Namespace. A namespace is a group of related elements that each have a unique name or identifier. A file path, which uses syntax defined by the operating system, is considered a namespace.

What is namespace C?

How do you use namespaces?

The way you can use classes from other namespaces is surprisingly very similar to the way in java. You can either use “use NAMESPACE” which is similar to an “import PACKAGE” statement, e.g. use std. Or you specify the package as prefix of the class separated with “::”, e.g. std::string. This is similar to “java.

What is the purpose of namespace?

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.

What is alias in C#?

The C# language allows developers to create aliases for lengthy fully qualified names or class names. The alias lives within the scope of the namespace it Is declared in. When the code compiles, a token is created for the fully qualified name and the alias is then in effect.
