Getting a Month Name Using Month Number in C#

Last Updated : 26 Oct, 2020

Given a number N (1<= N <=12), the task is to get a month name from a month number in C#.

Examples:

Input: N = 2
Output: February
  
Input: N = 5
Output: May

Method 1: Using DateTime.ToString() Method: This method can be used to get the both full and abbreviated name of the month.

Step 1: Get the Number N.
Step 2: Create an object of DateTime using the DateTime Struct.
DateTime date = new DateTime(year, month, day);;
Step 3: Converts the value of the current DateTime object to its equivalent string representation.
// to get the Abbreviated month name 
string month_name = date.ToString("MMM");

// to get the full month name 
string month_name = date.ToString("MMMM");
Step 4: This string contains the name of the month.

Below is the implementation of the above approach:

C#

// C# program to Get a Month Name
// from a Month Number
using System;
   
public class GFG{
     
    // function to get the abbreviated month name
    static string getAbbreviatedName(int month) 
    {
        DateTime date = new DateTime(2020, month, 1);
         
        return date.ToString("MMM");
    }
     
    // function to get the full month name
    static string getFullName(int month) 
    {
        DateTime date = new DateTime(2020, month, 1);
         
        return date.ToString("MMMM");
    }
     
    static public void Main ()
    { 
        int N = 3; 
        Console.WriteLine("Full Month Name : " + getFullName(N));
         
        N = 7;
        Console.WriteLine("Abbreviated Month : " + getAbbreviatedName(N));
    } 
}

Output:

Full Month Name : March
Abbreviated Month : Jul

Method 2: Using GetMonthName() Method: This method is used to get the full name of the month.

Step 1: Get the Number N.
Step 2: Create an object of CultureInfo and then get the month name using DateTimeFormat.GetMonthName() method.
// to get the full month name
string monthName = CultureInfo.CurrentCulture.
DateTimeFormat.GetMonthName(month);
Step 3: This string contains the name of the month.

Below is the implementation of the above approach:

C#

// C# program to Get a Month Name
// from a Month Number
using System;
using System.Globalization;
   
public class GFG{
     
    // function to get the full month name
    static string getFullName(int month) 
    {
        return CultureInfo.CurrentCulture.
            DateTimeFormat.GetMonthName
            (month);
    }
     
    static public void Main ()
    { 
        int N = 3; 
        Console.WriteLine("Full Month Name : " + getFullName(N));
         
        N = 7;
        Console.WriteLine("Full Month Month : " + getFullName(N));
    } 
}

Output:

Full Month Name : March
Full Month Month : July

Method 3: Using GetAbbreviatedMonthName() Method: This method is used to get the Abbreviated name of the month.

Step 1: Get the Number N.
Step 2: Create an object of CultureInfo and then get the month name using DateTimeFormat.GetAbbreviatedMonthName() method.
// to get the Abbreviated month name
string monthName = CultureInfo.CurrentCulture.
DateTimeFormat.GetAbbreviatedMonthName(month);
Step 3: This string contains the name of the month.

Below is the implementation of the above approach:

C#

// C# program to Get a Month Name
// from a Month Number
using System;
using System.Globalization;
   
public class GFG{
     
    // function to get the Abbreviated month name
    static string getAbbreviatedName(int month) 
    {
        return CultureInfo.CurrentCulture.
            DateTimeFormat.GetAbbreviatedMonthName
            (month);
    }
     
    static public void Main ()
    { 
        int N = 3; 
        Console.WriteLine("Abbreviated Month Name : " + getAbbreviatedName(N));
         
        N = 7;
        Console.WriteLine("Abbreviated Month Month : " + getAbbreviatedName(N));
    } 
}

Output:

Abbreviated Month Name : Mar
Abbreviated Month Month : Jul
