Date Structure |  |
Internal type that implements the VO Compatible DATE type
This type has many operators and implicit converters that normally are never directly called from user code. It holds year, month, day in 32 bits. For date calculations it uses the System.DateTime calculation logic. There are implicit converters between Date and DateTime.

| CompareTo(Object) | Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object. |
| CompareTo(Date) | Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object. |
| Equals(Object) | Indicates whether this instance and a specified object are equal. (Overrides Equals(Object).) |
| Equals(Date) | Indicates whether the current object is equal to another object of the same type. |
| GetHashCode | Returns the hash code for this instance. (Overrides GetHashCode.) |
| GetObjectData | Populates a SerializationInfo with the data needed to serialize the target object. |
| GetTypeCode | Returns the TypeCode for this instance. |
| Subtract(Double) | |
| Subtract(Long) | |
| Subtract(Int64) | |
| Subtract(TimeSpan) | |
| Subtract(DWord) | |
| Subtract(UInt64) | |
| Subtract(Date) | |
| Subtract(Usual) | |
| ToString | Returns the fully qualified type name of this instance. (Overrides ToString.) |
| ToString(IFormatProvider) | Converts the value of this instance to an equivalent String using the specified culture-specific formatting information. |
| ToString(String) | Converts the value of the current DateTime object to its equivalent string representation using the specified format and the formatting conventions of the current culture. |
| ToString(String, IFormatProvider) | Formats the value of the current instance using the specified format. |
