SqlDateTime Struct

Definition

Namespace:

System.Data.SqlTypes

Assembly:

System.Data.Common.dll

Source:

SQLDateTime.cs

Represents the date and time data ranging in value from January 1, 1753 to December 31, 9999 to an accuracy of 3.33 milliseconds to be stored in or retrieved from a database. The SqlDateTime structure has a different underlying data structure from its corresponding .NET type, DateTime, which can represent any time between 12:00:00 AM 1/1/0001 and 11:59:59 PM 12/31/9999, to the accuracy of 100 nanoseconds. SqlDateTime actually stores the relative difference to 00:00:00 AM 1/1/1900. Therefore, a conversion from "00:00:00 AM 1/1/1900" to an integer will return 0.

Constructors

SqlDateTime(DateTime)	Initializes a new instance of the SqlDateTime structure using the specified DateTime value.
SqlDateTime(Int32, Int32, Int32, Int32, Int32, Int32, Double)	Initializes a new instance of the SqlDateTime structure using the supplied parameters to initialize the year, month, day, hour, minute, second, and millisecond of the new structure.
SqlDateTime(Int32, Int32, Int32, Int32, Int32, Int32, Int32)	Initializes a new instance of the SqlDateTime structure using the supplied parameters to initialize the year, month, day, hour, minute, second, and microsecond of the new structure.
SqlDateTime(Int32, Int32, Int32, Int32, Int32, Int32)	Initializes a new instance of the SqlDateTime structure using the supplied parameters to initialize the year, month, day, hour, minute, and second of the new structure.
SqlDateTime(Int32, Int32, Int32)	Initializes a new instance of the SqlDateTime structure using the supplied parameters to initialize the year, month, day.
SqlDateTime(Int32, Int32)	Initializes a new instance of the SqlDateTime structure using the supplied parameters.

Fields

MaxValue	Represents the maximum valid date value for a SqlDateTime structure.
MinValue	Represents the minimum valid date value for a SqlDateTime structure.
Null	Represents a DBNull that can be assigned to this instance of the SqlDateTime structure.
SQLTicksPerHour	A constant whose value is the number of ticks equivalent to one hour.
SQLTicksPerMinute	A constant whose value is the number of ticks equivalent to one minute.
SQLTicksPerSecond	A constant whose value is the number of ticks equivalent to one second.

Properties

DayTicks	Gets the number of ticks representing the date of this SqlDateTime structure.
IsNull	Indicates whether this SqlDateTime structure is null.
TimeTicks	Gets the number of ticks representing the time of this SqlDateTime structure.
Value	Gets the value of the SqlDateTime structure. This property is read-only.

Methods

Add(SqlDateTime, TimeSpan)	Adds a SqlDateTime to the specified TimeSpan.
CompareTo(Object)	Compares this SqlDateTime structure to the supplied Object and returns an indication of their relative values.
CompareTo(SqlDateTime)	Compares this SqlDateTime structure to the supplied SqlDateTime structure and returns an indication of their relative values.
Equals(Object)	Compares the supplied object parameter to the Value property of the SqlDateTime object.
Equals(SqlDateTime, SqlDateTime)	Performs a logical comparison of two SqlDateTime structures to determine whether they are equal.
Equals(SqlDateTime)	Indicates whether the current instance is equal to another instance of the same type.
GetHashCode()	Gets the hash code for this instance.
GetXsdType(XmlSchemaSet)	Returns the XML Schema definition language (XSD) of the specified XmlSchemaSet.
GreaterThan(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is greater than the second.
GreaterThanOrEqual(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is greater than or equal to the second.
LessThan(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is less than the second.
LessThanOrEqual(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is less than or equal to the second.
NotEquals(SqlDateTime, SqlDateTime)	Performs a logical comparison of two instances of SqlDateTime to determine whether they are not equal.
Parse(String)	Converts the specified String representation of a date and time to its SqlDateTime equivalent.
Subtract(SqlDateTime, TimeSpan)	Subtracts the specified Timespan from this SqlDateTime instance.
ToSqlString()	Converts this SqlDateTime structure to SqlString.
ToString()	Converts this SqlDateTime structure to a String.

Operators

Addition(SqlDateTime, TimeSpan)	Adds the period of time indicated by the supplied TimeSpan parameter, t, to the supplied SqlDateTime structure.
Equality(SqlDateTime, SqlDateTime)	Performs a logical comparison of two SqlDateTime structures to determine whether they are equal.
Explicit(SqlDateTime to DateTime)	Converts the SqlDateTime structure to a DateTime structure.
Explicit(SqlString to SqlDateTime)	Converts the SqlString parameter to a SqlDateTime.
GreaterThan(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is greater than the second.
GreaterThanOrEqual(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is greater than or equal to the second.
Implicit(DateTime to SqlDateTime)	Converts a DateTime structure to a SqlDateTime structure.
Inequality(SqlDateTime, SqlDateTime)	Performs a logical comparison of two instances of SqlDateTime to determine whether they are not equal.
LessThan(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is less than the second.
LessThanOrEqual(SqlDateTime, SqlDateTime)	Compares two instances of SqlDateTime to determine whether the first is less than or equal to the second.
Subtraction(SqlDateTime, TimeSpan)	Subtracts the supplied TimeSpan structure, t, from the supplied SqlDateTime structure.
