DateTimeFormatInfo.MonthNames Property

Gets or sets a one-dimensional array of type String containing the culture-specific full names of the months.

[Visual Basic]
Public Property MonthNames As String ()
public string[] MonthNames {get; set;}
public: __property String* get_MonthNames();
public: __property void set_MonthNames(String* __gc[]);
public function get MonthNames() : String[];
public function set MonthNames(String[]);

Property Value

A one-dimensional array of type String containing the culture-specific full names of the months. In a 12-month calendar, the 13th element of the array is an empty string. The array for InvariantInfo contains "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December", and "".


Exception Type Condition
ArgumentNullException The property is being set to a null reference (Nothing in Visual Basic).
ArgumentException The property is being set to an array that is multidimensional or whose length is not exactly 13.
InvalidOperationException The property is being set and the DateTimeFormatInfo is read-only.


If setting this property, the array must be one-dimensional and must have exactly 13 elements. Calendar objects accommodate calendars with 13 months.

If the custom pattern includes the format pattern "MMMM", DateTime.ToString displays the value of MonthNames in place of the "MMMM" in the format pattern.

This property is affected if the value of the Calendar property changes.
