Extension Methods

VBVarTypeExtensions.VarType(VBType)

Remarks

The managed type of a value of this data type is DateTime.
👉 Date values are also representable as a double via SerialValue (OLE Automation/OADate value).

Constructors

VBDateType()

A VBIntrinsicType<T> representing the Date data type.

public VBDateType()

Remarks

The managed type of a value of this data type is DateTime.
👉 Date values are also representable as a double via SerialValue (OLE Automation/OADate value).

Fields

MaxSerial

The maximum valid value for a DateSerial.

public const double MaxSerial = 2958465.999998843

Field Value

double

Remarks

Corresponds to 9999-12-31T23:59:59Z

MinSerial

The minimum valid value for a DateSerial.

public const double MinSerial = -657434

Field Value

double

Properties

DefaultValue

Gets the default value for this data type.

public override VBTypedValue DefaultValue { get; }

Property Value

VBTypedValue

Remarks

⚠️ Derived types must back the implementation of this property with a thread-safe private static readonly Lazy<T>. Failure to do so would lock up the static context initialization of the StaticSymbol symbols.

MaxValue

Gets the maximum representable value for this data type.

public static VBDateValue MaxValue { get; }

Property Value

VBDateValue

MinValue

Gets the minimum representable value for this data type.

public static VBDateValue MinValue { get; }

Property Value

VBDateValue

TypeInfo

The Date data type.

public static VBDateType TypeInfo { get; }

Property Value

VBDateType

Zero

Gets the value 0 (zero) representation of this data type.

public static VBDateValue Zero { get; }

Property Value

VBDateValue

Methods

CreateValue(IBindingHandle)

Creates a value of this type bound to handle.

public override VBTypedValue CreateValue(IBindingHandle handle)

Parameters

handle IBindingHandle

Returns

VBTypedValue

Remarks

The base implementation throws: only types that can hold a runtime value override this (matches the intent of the removed VBTypedValueFactory.CreateValue(VBType) switch, which returned null for the rest).

IsValidSerial(double)

Whether a Date holds serial: any serial strictly between -657435 and 2958466, a time of day from 100-01-01 to 9999-12-31, which is wider than MinSerial and MaxSerial by the fractions of a second past them (MS-VBA, recorded in Excel). A value past either end is not a Date: converting it to one, or a Date operation that yields it, is run-time error 6, Overflow.

public static bool IsValidSerial(double serial)

Parameters

serial double

The serial (Double) representation of a date.

Returns

bool
