Method Overloading in C#


The Method Overloading is defined as Defining More than One Method with the same Name or In Other words we can say that, contain Multiple Methods with the Same Name under the same Class.
These Methods Are differentiated by the type of parameter or variating by the having more than one parameter But Changing of return type of Method is Invalid and Complier will throw error. Not a valid Method. These are mainly derived from the Base library – “System” Class.
Example,


Here in This Example,
Form1 Class Has Method – “MethodOverLoadingDemo”, And this Has been Overloaded with Multiple times as mentioned in the image.
MethodOverLoadingDemo à Normal Private Method has been Defined.
MethodOverLoadingDemo(string str= “MethodOverLoadingDemo”) à Overloaded the previous
Method by String Parameter.
MethodOverLoadingDemo(int MethodCount = 3) à Overloaded the previous Method by int Parameter.
And All the Above Methods are Non-Value Return Type I.e. Void Type but Below Method is string return Type, this is not a valid Statement Allowed in c#, because this an invalid Overloading it will throw an error as already same method is defined- Mentioned in the image
String MethodOverLoadingDemo(int MethodCount = 3) à Invalid Overloading

Abstract Class And Abstract Methods in C# The Abstract class is a class can contain both Abstract and Non-Abstract Method, to consume the non-Abstract method available in the abstract class then it is required or mandate to implement the abstract method of abstract Class. Abstract Methods  à  Defining the declaration of method I.e. Method without method body and the implementation of this method is available in the child class. Example, abstract   public   class   ParentClass // Parent Class          {              public   abstract   void  Display();              public   void  NormalMethod()              {               ...

Attribute in c# An attribute is mainly derived from the library –  “System.Diagnostics”  but all the attributes were inherited from the Sealed class called Attribute this attribute class were basically implemented with the help of  “System.Relfection and System.Runtime.InteropServices”.  this will help to avoid writing complicated logic to validate the basic details and to restrict the operation to be performed with the properties/class/Methods. What is Attribute in c#? Attribute is used to provide a details information about a property or class or a method and even for structure behavior as well during the run time of an application execution (even for a console application). An Attribute is defined above a class or method or a property will define the functionality of that element. A attribute is defined by  square ([ ]) Brace  used above the required element. The .Net Framework supports 2 attributes types: 1.     ...

Reflection   in C# The Reflection is mainly derived from the Base library –  “System.Reflection ”,  This reflection can be mainly used to specify the details such as meta data, In Other words, Reflection is used to provide the meta details of a property or a class or method. Suppose we have a class to be referred and need to access the object or a method from that class, in this case, we can go for reflection to access the property by providing the valid data about the property and can retrieve the value of the property in our calling class. It will throw error incase we have provided invalid property name or class name or simply the name of element at compile time, but it will throw exception in case of failure at the run time of the application. Example, AssemblyName                  è            Retrieve the unique name of an assembly EventInfo  ...
