The Function defined with in class is called method. It is a code designed to work on the member data of class.

 

Methods are operations associated with types. To provide a type with methods is to give it some useful functionality. Often this functionality is made generally available, so that it can be utilized by other types.

When many people work in creating the same program, it could be difficult to keep track of the names of various classes. If more than one programmer creates a class with the same name in the same program, there would be conflict and the program would not work. The solution to avoid this situation is to delimit sections of code with names.

C# has a strong feature in which we can define more than one class with the Main method. Since Main is the entry point for the program execution, there are now more than one entry points. In fact, there should be only one entry point. Which will be resolved by specifying which Main is to be used to the compiler at the time of compilation as shown below:

An enumeration is a special set of numeric type string literals which considered as a constants.

An enumeration is a special kind of value type limited to a restricted and unchangeable set of numerical values. By default, these numerical values are integers, but they can also be longs, bytes, etc. (any numerical/value except char) as will be illustrated below.

Structure is a user-defined value type which encapsulates member data and member function.

A struct is a user-defined value type. It is declared in a very similar way to a class, except that it can't inherit from any class, nor can any class inherit from it (as mentioned\ previously, however, all value types do inherit from System.object), The following example shows a partial declaration for a 'Coordinate' struch.

C# uses a series of words, called keywords, for its internal use. This means that you must avoid naming your objects using one of these keywords.

In the body of a method, you can also declare variables that would be used internally. A variable declared in the body is referred to as a local variable. It cannot be accessed outside of the method it belongs to. After declaring a local variable, it is made available to the method and you can use it.

Command line arguments are parameters supplied to the Main method at the time of invoking it for execution. To understand the concepts see the example given below:

Program of Command line argument to accept name from the command line and writes to the console. (Sample.cs)

Identifiers refer to the names of variables, functions arrays, classes, etc. created by programmer. They are fundamental requirement of any language. Each language has its own rules for naming these identifiers.
