Single Inheritance in C#

-
In this article we are going to see, Inheritance in C#.So, What is an Inheritance in C# ? An Inheritance is a concept or approach where one type can derived from other type. Just like a son gets his DNA from his parents. In c#, we can derive a type from other type. So the child type can inherit its parent type members. ( Members mean Methods,Property etc.)Now , we will see Single Inheritance where a class and inherit only one class. A class can not be derived from more than one class that’s why we called it as Single Inheritance. (Type means Classes,Interfaces and Abstract classes).Following is a simple program to understand it.

Code Snippet:-

/// <summary>
/// Abstract class
/// </summary>
public abstract class AbsClass
{

/// <summary>
/// Abstract method declaration
/// </summary>
/// <param name="_input"></param>
public abstract void WhatUgot(int _input);

}

/// <summary>
/// Non Abstract Class derived from Abstract class
/// </summary>
public class NonAbsClass : AbsClass
{

///// <summary>
///// Overriden Mthod
///// </summary>
///// <param name="_input"></param>
public override void WhatUgot(int _input)
{
Console.WriteLine("This is Overriden Method");
}
}

public class SingleInheritance
{ 
public static void Main()
{
NonAbsClass obj = new NonAbsClass();
obj.WhatUgot(1);
Console.ReadLine();
}
}

In the above example, We have derived “NonAbsClass” from Abstract class “AbsClass” and inherited its Method. Means we overrode the Abstract method of Abstract Class “AbsClass” in Non-Abstract Class “NonAbsClass”. Point to remember is we can not derive a normal class from more than one Class or Abstract Class that’s why we called it Single Inheritance.

In this article we are going to see, How to transpose DataTable in C#? It means we are going to convert DataRow into DataColumn and DataColumn intoDataRow.Following is the simple and self-explanatory example in the form of code comment. Code Snippet:- using System; using System.Collections.Generic; using System.Data; using System.Linq; using System.Text; using System.Threading.Tasks; namespace BlogsProgram { public class TansposeDataTableClass { public void TransposeDataTable() { // Defined Table as "Employee". DataTable dt = new DataTable("Employee"); // Defined "EmpID" column as Integer Datatype. dt.Columns.Add("EmpID", typeof(Int32)); // Defined "EmpName" column as String Datatype. dt.Columns.Add("EmpName", typeof(string)); // Defined "EmpRank" column as String Datatype. dt.Columns.Add(...

Multiple Inheritance in C#

In this article we are going to see, Inheritance in C#. So, What is an Inheritance in C#? An Inheritance is a concept or approach where one type can be derived from other types Just like a son gets his DNA from his parents. In c#, we can derive a type from other types. So the child type can inherit its parent type members such as Methods, Property, etc. Now, we will see Multiple Inheritance where a class can derive from more than one type. But for that, a class has to derive from Interfaces. Because Interfaces supports multiple Inheritance, a normal class derived from only one Class and multiple interfaces. (Type means Classes, Interfaces, and Abstract classes)Following is a simple program to understand it. Code Snippet:- public interface Interface1 { /// <summary> /// Abstract method declaration /// </summary> /// <param name="_input"></param> void WhatUgot(int _input); } public interface Interface2 { /// <summary> /// Abstract...
