Get Month name from month number

Question

For short month names use:

string monthName = new DateTime(2010, 8, 1)
    .ToString("MMM", CultureInfo.InvariantCulture);

For long/full month names for Spanish ("es") culture

string fullMonthName = new DateTime(2015, i, 1).ToString("MMMM", CultureInfo.CreateSpecificCulture("es"));

For Abbreviated Month Names : "Aug"

DateTimeFormatInfo.GetAbbreviatedMonthName Method (Int32)

Returns the culture-specific abbreviated name of the specified month based on the culture associated with the current DateTimeFormatInfo object.

string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(8)

For Full Month Names : "August"

DateTimeFormatInfo.GetMonthName Method (Int32)

Returns the culture-specific full name of the specified month based on the culture associated with the current DateTimeFormatInfo object.

string monthName = CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(8);

Replace GetMonthName with GetAbbreviatedMonthName so that it reads:

string strMonthName = mfi.GetAbbreviatedMonthName(8);

You can get this in following way,

DateTimeFormatInfo mfi = new DateTimeFormatInfo();
string strMonthName = mfi.GetMonthName(8).ToString(); //August

Now, get first three characters

string shortMonthName = strMonthName.Substring(0, 3); //Aug
