  NameDescription
Add Adds the value of the specified TimeSpan to the value of this instance.
AddDays Adds the specified number of days to the value of this instance.
AddHours Adds the specified number of hours to the value of this instance.
AddMilliseconds Adds the specified number of milliseconds to the value of this instance.
AddMinutes Adds the specified number of minutes to the value of this instance.
AddMonths Adds the specified number of months to the value of this instance.
AddSeconds Adds the specified number of seconds to the value of this instance.
AddTicks Adds the specified number of ticks to the value of this instance.
AddYears Adds the specified number of years to the value of this instance.
Compare Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.
CompareToOverloaded. Compares the value of this instance to a specified DateTime value and indicates whether this instance is earlier than, the same as, or later than the specified DateTime value.
DaysInMonth Returns the number of days in the specified month and year.
EqualsOverloaded. Returns a value indicating whether two DateTime objects, or a DateTime instance and another object or DateTime are equal.
Finalize Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
FromBinary Deserializes a 64-bit binary value and recreates an original serialized DateTime object.
FromFileTime Converts the specified Windows file time to an equivalent local time.
FromFileTimeUtc Converts the specified Windows file time to an equivalent UTC time.
FromOADate Returns a DateTime equivalent to the specified OLE Automation Date.
GetDateTimeFormatsOverloaded. Converts the value of this instance to all the string representations supported by the standard DateTime format specifiers.
GetHashCode Returns the hash code for this instance. (Overrides ValueType..::.GetHashCode()()().)
GetType Gets the Type of the current instance. (Inherited from Object.)
GetTypeCode Returns the TypeCode for value type DateTime.
IsDaylightSavingTime Indicates whether this instance of DateTime is within the Daylight Saving Time range for the current time zone.
IsLeapYear Returns an indication whether the specified year is a leap year.
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ParseOverloaded. Converts the specified string representation of a date and time to its DateTime equivalent.
ParseExactOverloaded. Converts the specified string representation of a date and time to its DateTime equivalent. The format of the string representation must match a specified format exactly or an exception is thrown.
SpecifyKind Creates a new DateTime object that represents the same time as the specified DateTime, but is designated in either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value.
SubtractOverloaded. Subtracts the specified time or duration from this instance.
ToBinary Serializes the current DateTime object to a 64-bit binary value that subsequently can be used to recreate the DateTime object.
ToFileTime Converts the value of the current DateTime object to a Windows file time.
ToFileTimeUtc Converts the value of the current DateTime object to a Windows file time.
ToLocalTime Converts the value of the current DateTime object to local time.
ToLongDateString Converts the value of the current DateTime object to its equivalent long date string representation.
ToLongTimeString Converts the value of the current DateTime object to its equivalent long time string representation.
ToOADate Converts the value of this instance to the equivalent OLE Automation date.
ToShortDateString Converts the value of the current DateTime object to its equivalent short date string representation.
ToShortTimeString Converts the value of the current DateTime object to its equivalent short time string representation.
ToStringOverloaded. Converts the value of the current DateTime object to its equivalent string representation.
ToUniversalTime Converts the value of the current DateTime object to Coordinated Universal Time (UTC).
TryParseOverloaded. Converts the specified string representation of a date and time to its DateTime equivalent and returns a value that indicates whether the conversion succeeded.
TryParseExactOverloaded. Converts the specified string representation of a date and time to its DateTime equivalent. The format of the string representation must match a specified format exactly. The method returns a value that indicates whether the conversion succeeded.

  NameDescription
Addition Adds a specified time interval to a specified date and time, yielding a new date and time.
Equality Determines whether two specified instances of DateTime are equal.
GreaterThan Determines whether one specified DateTime is greater than another specified DateTime.
GreaterThanOrEqual Determines whether one specified DateTime is greater than or equal to another specified DateTime.
Inequality Determines whether two specified instances of DateTime are not equal.
LessThan Determines whether one specified DateTime is less than another specified DateTime.
LessThanOrEqual Determines whether one specified DateTime is less than or equal to another specified DateTime.
SubtractionOverloaded. Subtracts a specified DateTime or TimeSpan from a specified DateTime.
