User Defined Method() tutorials

  • Up till now we have worked with Main() method only. It is one and only method that consists of header and body of program. Now its time to use another method.

  • For smaller program Main() method is sufficient, while for complex and bigger program we can write separate functions and call it. This is known as method call, which is point at which function is called, where by actual function is inserted in program during linking to library files.

  • When program becomes large, it becomes difficult to manage it as single program. Hence one can divide program into smaller parts known as functions.

  • Function act individually and gives result.

  • Similarly, statements required repeatedly within programs can be written once as method, and can be called many times.

  • A function is a self-contained program that carries out some specific task.

  • Each C Program consists of one or more functions.

  • One of these Method must be Main(). Program execution begin from Main( ). And each function in program is called in the sequence specified by method call in Main().

  • Additional method will be subordinate to Main().

  • After each function completes its task, control returns to Main(). When all statements and other method calls completes, the program ends.

 

Components

  • Defining methods in C#: When you define a method, you basically declare the elements of its structure.

  • The syntax for defining a method in C# is as follows:

<access specifier> <return type> <method name> (parameter list)

{

Method body

}

Below is the various element of a method:

  • Access Specifier: This determines the visibility of a variable or a method from another class.

  • Return type: A method may return a value. The return type is the data type of the value the method returns. If the method is not returning any values, then the return type is void.

  • Method name: Method name is a unique identifier and it is case sensitive. It cannot be same as any other identifier declared in the class.

  • Parameter list: Enclosed between parentheses, the parameters are used to pass and receive data from a method. The parameter list refers to the type, order, and number of the parameters of a method. Parameters are optional; that is, a method may contain no parameters.

  • Method body: This contains the set of instructions needed to complete the required activity.

  • Calling a Method: User defined Method can be called inside Main thread by using Class object followed by period and object name as below example:

MyClassobj.method_name();
