C# Data Types

Data Types 

 In C# programming language, Data Types are used to define a type of data the variable can hold such as integer, float, string, boolean. in a software application.

 C# is a Strongly Typed programming language so before we perform any operation on variables, it’s mandatory to define a variable with required data type to indicate what type of data that variable can hold in a software application.


Syntax of declaring Data Type in C#

[Data Type] [Variable Name];
[Data Type] [Variable Name] = [Value];

From the above syntax, we added a required data type before the variable name to tell the compiler about what type of data the variable can hold or which data type the variable belongs to.

[Data Type] - It’s a type of data the variable can hold such as integer, string, decimal, boolean etc.

[Variable Name] - It’s a name of the variable to hold the values in an application.

[Value] - Assigning a required value to the variable.

Data Types Example using C#

namespace CSharpnaijaDataType
{
    class Program
    {
        static void Main(string[] args)
        {
            int number = 15;
            string name = "Musa Sule";
            double percentage = 15.23;
            char gender = 'M';
            bool isGood = true;
        }
    }
}

Different Data Type in C#


There are basically three different types of Data Type in C# Programming Language, these include
1.  Value Data Type - int, bool, char, double, float, etc
2.  Reference Data Type - string, class, object, interface, delegate, etc
3.  Pointer Data Type - Pointers

Classes in C# Explained

C# Class Explained A class is nothing but an encapsulation of properties and methods that are used to represent a real-time entity, as explained by Guru99 . For instance, if you want to work with Guest’s data as in our previous DataDriven Web application . The properties of the Guest would be the Id, GuestName, Address, Phone number etc of the Guest. The methods would include the entry and modification of Guest data. All of these operations can be represented as a class in C# as shown below. using System; namespace CsharpnaijaClassTutorial {     public class Guest     {         public int Id { get ; set ; }         public string GuestName { get ; set ; }         public string Address { get ; set ; }         public string WhomToSee { get ; set ; }     ...

ASP.NET MVC Routing

ASP.NET MVC Routing ASP.NET MVC routing is a pattern matching system that is responsible for mapping incoming browser requests to specified MVC controller actions. When the ASP.NET MVC application launches then the application registers one or more patterns with the framework's route table to tell the routing engine what to do with any requests that matches those patterns. When the routing engine receives a request at runtime, it matches that request's URL against the URL patterns registered with it and gives the response according to a pattern match. Routing pattern is as follows A URL is requested from a browser, the URL is parsed (that is, break into controller and action), the parsed URL is compared to registered route pattern in the framework’s route table, if a route is found, its process and send response to the browser with the required response, otherwise, the HTTP 404 error is send to the browser. Route Properties ASP.NET MVC routes are res...
