C# OOP Concepts: Apply C# OOP Concepts On Real C# Projects

A general introduction about the course. It represents which topics will be taught?

This video answers the what is OOP in C# question.

Class and object may be basis of OOP. These video explains class and object concepts and also explains relationship between class and object with examples.

Sometimes programmers may want to hold data safely. Such cases Encapsulation will be usefull. Encapsulation means protect important data inside the class which we don’t want to be exposed outside the class. Encapsulation process means binding the data members and member function in a single unit.  This video explains using of encapsulation with examples.

Static is a keyword that can be used to declare a member of a type so that it is specific to that type. When a member is declared static, it can be accessed with the name of its class directly. This video explains using of static statement in C# with examples.

Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. Inheritance provide us security and simplicity in code. This video explains using of inheritance types in C# with real examples.

Sometimes programmers need to use a contract to make all class similar for some properties. An interface is more like a contract and the class or struct that implements an interface must provide an implementation for all the members that are specified in the interface definition. This video explains all properties of interface with real examples in C#.

Polymorphism means providing an ability to take more than one form and it’s a one of the main pillar concept of object oriented programming, after encapsulation and inheritance. This video explains all information about Polymorphism with real examples in C#.

An abstract class is designed to be inherited by subclasses that either implement or override its methods. This video explains using of abstract class with real examples in C#

Normally classes are declared within a namespace, or in the default namespace if one is not specified. A nested class is defined within the code block of another class, which itself may be a nested class to permit multiple nesting levels. This video explains using of nested classes in .Net.

This video explains using and advantages of partial and sealed class in .Net framework.

Enumeration or enum is a value data type which is mainly used to assign the names or string values to integral constants, that make a program easy to read and maintain. This video explains using of enum in .Net with examples.

A function can have one or more parameters of different data types, but what if you want to pass a function itself as a parameter? How does C sharp handle the callback functions or event handler? The answer is delegate. This video explains using of Delegates in .Net with examples.

Exception Handling is a process to handle runtime errors. This video explains all information about exception handling with examples in .Net.

In professional projects each programmer needs to use files in project. such cases you have to use System IO class. This video explains most used property in System IO class in .Net framework.

For example in a project you can to control any folder like delete folder or create folder . Such cases you need Directory and Directory Class. This video explains using of Directory and Directory info class in .Net framework with real examples.

In projects you may want to make some file operations like add a photo or delete a pdf document. Such cases you need File and File Info Class. This video explains using of file and file info class in .Net with real examples.

In project folder or file properties may be very important for check. You can take any property of file or folder with Path class. This video explains using of Path class in .Net framework.

N-tier architecture is a client-server architecture concept in software engineering where the presentation, processing and data management functions are both logically and physically separated. In N-tier, "N" refers to a number of tiers or layers are being used like – 2-tier, 3-tier or 4-tier, etc. It is also called Multi-Tier Architecture Or multi-layer architecture.

In my opinion to make a program with best codes we have to determine all necessaries in project that we will need. This video shows us final version of personal tracking app that we will make step by step in following videos.

While making a project first you have to determine project Construction stages to follow true steps . this video explains the project Construction stages of personal tracking app that we will make step by step in following videos.

For holding any data in your project as you know you have to use a database. This video is a part of making personal tracking app video list that we will create our project’s database.

We will use 3 tier architecture in our project. This video is a part of making personal tracking app video list that we will create our project’s structure with adding layers.

This video is a part of making personal tracking app video list that we will design salary and salary list pages.

This video is a part of making personal tracking app video list that we will connect forms for access each form in project

In .Net there are some options to make SQL operations easily like entity framework or LINQ to SQL . in our project we will use LINQ. This video is a part of making personal tracking app video list that we will connect our database to project with help of LINQ.

This video is a part of making personal tracking app video list, that we will add department with help of insert command in LINQ.

This video is a part of making personal tracking app video list, that we will select all departments and show in datagrid view on department list form.

This video is a part of making personal tracking app video list, that we will add position with help of insert command in LINQ.

As you know each user may make some errors during the adding process. So in any program if you have an add process also you need an update process. This video is a part of making personal tracking app video list, that we will update permissions easily with help of submit changes command in LINQ.

This video is a part of making personal tracking app video list, that we will update tasks easily with help of submit changes command in LINQ.

This video is a part of making personal tracking app video list, that we will delete unnecessary salaries easily with help of delete on submit command in LINQ.

In big project there will be some relationship with some tables . for example in our project permission is an employee property if you delete any employee this means you have to delete all properties of employee. Such cases to make this process easily we can use triggers.

This video is a part of making personal tracking app video list, that we will delete unnecessary positions easily with help of delete on submit command in LINQ and using Triggers.

This video is a part of making personal tracking app video list, that we will delete unnecessary departments easily with help of delete on submit command in LINQ and using Triggers.

As you know in professional programs have some authority to hide some properties from limited authorized users. For example an admin user makes everything in project but a standard user can not delete any user etc. This video is a part of making personal tracking app video list, that we will make Authorization Operations.

As you know excel is an important assistance that people use for tables data and as youknow data grids are also a table. Peoples like to send data from program to excel for make some operations easily. This video is a part of making personal tracking app video list, that we will make Export to Excel Operations.

Software design patterns are common solutions to problems which are regularly encountered in programming. This video explains design pattern’s advantages and types. And following videos we will examine some of them.

Design patterns are classified in tree groups. Creational, Structural and Behavioral. This video explains using of Abstract Factory pattern which is classified in Creational design patterns in C# with examples.

Design patterns are classified in tree groups. Creational, Structural and Behavioral. This video explains using of Observer pattern which is classified in behavioral design patterns in C# with examples.
