Month in C#

Question

Is there any function in C#, if we give the numeric value of a month it will give character as an output. For example: Input is say 1 Output is January Input is say 12 Output is December

Vulpes · Answer

There is in fact a way to do this directly from the .NET Framework using a method in the CultureInfo class: int monthNumber = 11; // say string monthName = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(monthNumber); Console.WriteLine(monthName); // November

Here's a link to the MSDN docs for the String.Substring method: http://msdn.microsoft.com/en-us/library/system.string.substring.aspx

Program is working. Thank you for your help. int m = int.Parse(bDay.Substring(0, 2)); This code is new to me. Please give me relevant website addresses where I can learn about this code.

The program is assuming that the birth date is being input in 'mm/dd/yyyy' format and that, consequently, the first two characters are the month number. You therefore need to enter a birth date in the format 01/01/1111 etc. or change it so that it can cope with single digit months or days.

Program is giving following output to the point below: Name #1 A Phone No 123456 Birth Day (mm/dd/yyyy) 1/1/1111 Name #2 Q Phone No 654321 Birth Day (mm/dd/yyyy) 2/2/2222 Name #3 Z Phone No 123567 Birth Day (mm/dd/yyyy) 3/3/3333 Name #1 A Phone No 123456 Birth Day 1/1/1111 Name #2 Q Phone No 654321 Birth Day 2/2/2222 Name #3 Z Phone No 123567 Birth Day 3/3/3333 Enter friend's name A At this point there is an error signal saying that Formal Exemptions was unhandled. It is indicating following step. int m = int.Parse(bDay.Substring(0, 2)); Program is attached.

Try this: using System; using System.Globalization; namespace _6e13_a_b_c_d_ { class Program { static void Main(string[] args) { Friend[] friend = new Friend[3]; for (int x = 0; x { friend[x] = new Friend(); Console.Write("Name #{0} ", x+1); friend[x].setName(Console.ReadLine()); Console.Write("Phone No "); friend[x].setPNo(Convert.ToInt32(Console.ReadLine())); Console.Write("Birth Day (mm/dd/yyyy) "); friend[x].setBday(Console.ReadLine()); Console.WriteLine(); } Array.Sort(friend); for (int x = 0; x Console.WriteLine("Name #{0} {1} Phone No {2} Birth Day {3}", x + 1, friend[x].getName(), friend[x].getPNo(), friend[x].getBday()); Console.WriteLine(); Console.Write("Enter friend's name "); string fn = Console.ReadLine(); for (int x = 0; x if (friend[x].getName()==fn) { string bDay = friend[x].getBday(); int m = int.Parse(bDay.Substring(0, 2)); string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(m); bDay = monthName + bDay.Substring(2).Replace("/", " "); Console.WriteLine("Name #{0} Phone No {1} Birth Day {2}", x + 1, friend[x].getPNo(), bDay); Console.WriteLine(); Console.WriteLine("Those other friends (if any) which have a birthday in the same month are listed below"); Console.WriteLine(); for(int y = 0; y { if (y == x) continue; string bDay2 = friend[y].getBday(); int m2 = int.Parse(bDay2.Substring(0, 2)); if (m == m2) { bDay2 = monthName + bDay2.Substring(2).Replace("/", " "); Console.WriteLine("Name #{0} {1} Phone No {2} Birth Day {3}", y + 1, friend[y].getName(), friend[y].getPNo(), bDay2); } } break; } Console.ReadKey(); } } } internal class Friend : IComparable { private string name; private int pNo; private string bDay; public string getName() { return this.name; } public void setName(string name) { this.name = name; } public int getPNo() { return this.pNo; } public void setPNo(int pNo) { this.pNo = pNo; } public string getBday() { return this.bDay; } public void setBday(string bDay) { this.bDay = bDay; } public int CompareTo(Friend firstName) { return string.Compare(this.name, firstName.name); } }

Above idea is incorporated into this program to do the part 13(c) but no idea to do the last part that is 13(d). Anyone have idea please tell me. This is chapter 6 which I attach. using System; using System.Globalization; namespace _6e13_a_b_c_d_ { class Program { static void Main(string[] args) { Friend[] friend = new Friend[3]; for (int x = 0; x { friend[x] = new Friend(); Console.Write("Name #{0} ", x+1); friend[x].setName(Console.ReadLine()); Console.Write("Phone No "); friend[x].setPNo(Convert.ToInt32(Console.ReadLine())); Console.Write("Birth Day (mm/dd/yyyy) "); friend[x].setBday(Console.ReadLine()); Console.WriteLine(); } Array.Sort(friend); for (int x = 0; x Console.WriteLine("Name #{0} {1} Phone No {2} Birth Day {3}", x + 1, friend[x].getName(), friend[x].getPNo(), friend[x].getBday()); Console.WriteLine(); Console.Write("Enter friends name "); string fn = Console.ReadLine(); for (int x = 0; x if (friend[x].getName()==fn) Console.WriteLine("Phone No {0} Birth Day mm/dd/yyyy {1}", friend[x].getPNo(), friend[x].getBday()); Console.WriteLine(); Console.Write("Birthday month in a numeric format: "); int m = Convert.ToInt32(Console.ReadLine()); string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(m); Console.WriteLine("Birthday is in {0}", monthName); Console.ReadKey(); } } } internal class Friend : IComparable { private string name; private int pNo; private string bDay; public string getName() { return this.name; } public void setName(string name) { this.name = name; } public int getPNo() { return this.pNo; } public void setPNo(int pNo) { this.pNo = pNo; } public string getBday() { return this.bDay; } public void setBday(string bDay) { this.bDay = bDay; } public int CompareTo(Friend firstName) { return string.Compare(this.name, firstName.name); } }

Sure, you can add a using directive as follows: using System; using System.Globalization; class Test { static void Main() { Console.Write("Month No "); int m = Convert.ToInt32(Console.ReadLine()); string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(m); Console.WriteLine(monthName); Console.ReadKey(); } } Notice also that it's easy to get the month names in different languages with this approach. For example, if you change the above line to: string monthName = CultureInfo.GetCultureInfo("fr-FR").DateTimeFormat.GetMonthName(monthNumber); and enter 11 for monthNumber, then the output will be: novembre

Maha · Answer

This is what I am looking for. I slightly modify your idea. I wish to use using directive for the following one. Because it is too long. string monthName = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(m); Please tell me the correct using directive for this. Also thank you for your help. using System; class Test { static void Main() { Console.Write("Month No "); int m = Convert.ToInt32(Console.ReadLine()); string monthName = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(m); Console.WriteLine(monthName); Console.ReadKey(); } }

If you give the GetMonth method a month number between 1 and 12, it will in fact return the month as a string - January to December. Try it and see.

Hi, I think there is no Build in function in .Net to do this. You may try this function 1) Give " Microsoft.SqlServer.Smo " dll reference to your Project. 2) Try using Microsoft.SqlServer.Management.Smo; public string GetMonthName(int Month_ID) { switch (Month_ID) { case (int)Month.January: return Month.January.ToString(); break; case (int)Month.February: return Month.February.ToString(); break; default: return "Invalid Input"; break; } } If this post helps you, then mark as "Correct Answer". Thank You

Maha · Answer

Sorry my question is not clear enough therefore I didn't get the required reply. For example: Console input is 1 Console output is January

Vulpes · Answer

Try this: using System; class Test { static void Main() { string s = GetMonth(1); Console.WriteLine(s); s = GetMonth(12); Console.WriteLine(s); Console.ReadKey(); } static string GetMonth(int monthNumber) { if (monthNumber 12) throw new ArgumentOutOfRangeException(); return new DateTime(1, monthNumber, 1).ToString("MMMM"); } }
