Models in ASP.NET MVC


Models in ASP.NET MVC Explained


A model is a class that contains the business logic of your application. It also used for accessing data from the database. The model class does not handle directly input from the browser. In MVC, it is the Controller that handle input from the browser directly and process the request by receiving data from the model and pass it back to view as response. It does not contain any HTML code either.

It is a best practice but not mandatory for developers to not have any communications with the view directly, models should only contain a POCO (Plain Old CLR Objects) classes. All processing logic and communication with the view should be handled by another layer called Viewmodels.

Models are also refers as objects that are used to implement conceptual logic for the application. A controller interacts with the model, access the data, perform the logic and pass that data to the view.

Note that it is not mandatory, but it is a good programming practice to store all model classes within the Models folder of MVC application.

Creating a Model


Let's add a new model in exiting project created in our previous article here. Model contains set and get for its properties.

To add the model, just right click on the Models folder of the project, select Add then click on New Item as shown below


Under Visual C# installed template, click on Code on the left hand side of the Add new Item window select Class from the middle panel of the window as shown below;

Enter the name of the model class as Employee and click on Add as shown below;

Enter the properties of our Employee Class (Model) as follows;
Id, First Name, Middle Name, Last Name, Sex, Date of Birth, Address and phone number

The properties should entered in between the opening and closing curly brace of the Employee Class as shown below

Collections in C#

Collections in C# In our previous article , we have learned about how we can use arrays in C#. Arrays in programming are used to group a set of related objects. So one could create an array or a set of Integers, which could be accessed via one variable name. What is Collections in C#? Collections are similar to Arrays, it provides a more flexible way of working with a group of objects. In arrays, you would have noticed that you need to define the number of elements in an array beforehand. This had to be done when the array was declared. But in a collection, you don't need to define the size of the collection beforehand. You can add elements or even remove elements from the collection at any point of time. This article will focus on how we can work with the different collections available in C#. There are three distinct collection types in C#: standard generic concurrent The standard collections are found under the System.Collections. They do not store elemen...

System.IO Namesapce in C#

  System.IO Namesapce in C# A  file  is a collection of data stored in a disk with a specific name and a directory path. When a file is opened for reading or writing, it becomes a  stream . The stream is basically the sequence of bytes passing through the communication path. There are two main streams: the  input stream  and the  output stream . The  input stream  is used for reading data from file (read operation) and the  output stream  is used for writing into the file (write operation). From the above definition of file, the C# provides a namespace that enable us to manipulate file in C# called System.IO.   System.IO  is a  namespace  and it contains a standard IO (input/output) types such as classes , structures , enumerations , and  delegates  to perform a read/write operations on different sources like file, memory, network, etc.   System.IO Classes The table below shows differen...
