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

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...

The String.Join Method in C# Explained

The String.Join Method in C#   The string.Join concatenates the elements of a specified array or the members of a collection, using the specified separator between each element or member. Overloads of string.Join Method Description Join(Char, Object[]) Concatenates the string representations of an array of objects, using the specified separator between each member. Join(Char, String[]) Concatenates an array of strings, using the specified separator between each member. Join(String, IEnumerable<String>) Concatenates the members of a constructed IEnumerable<T> collection of type String, using the specified separator between each member. Join(String, Object[]) Concatenates the elements of an object array, using the specified separator between each element. Join(String, String[]) Concatenates all the elements of a string array, usi...

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...
