DateTime::MaxValue Field

Represents the largest possible value of DateTime. This field is read-only.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public:
static initonly DateTime MaxValue

The value of this constant is equivalent to 23:59:59.9999999, December 31, 9999, exactly one 100-nanosecond tick before 00:00:00, January 1, 10000.

Some calendars, such as the UmAlQuraCalendar, support an upper date range that is earlier than MaxValue. In these cases, trying to access MaxValue in variable assignments or formatting and parsing operations can throw an ArgumentOutOfRangeException. Rather than retrieving the value of DateTime::MaxValue, you can retrieve the value of the specified culture's latest valid date value from the System.Globalization.CultureInfo.DateTimeFormat.Calendar.MaxSupportedDateTime property.

The following example instantiates a DateTime object by passing its constructor an Int64 value that represents a number of ticks. Before invoking the constructor, the example ensures that this value is greater than or equal to DateTime.MinValue.Ticks and less than or equal to DateTime.MaxValue.Ticks. If not, it throws an ArgumentOutOfRangeException.
