BitsFromValue(PrimitiveDataType,UInt64,Int32) Method



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.DataTypeModel Namespace > SequenceData Class > BitsFromValue Method : BitsFromValue(PrimitiveDataType,UInt64,Int32) Method
The primitive data type to be associated with the elements.

The value of this parameter can be null (Nothing in Visual Basic).

The value to be converted to a sequence of bits.
The number of bits from the value to be converted.

Valid values of this parameter are in the range from 0 to 2147483647 (Int32.MaxValue).

Creates sequence data from bits of an unsigned integer value, given the primitive data type for the bits.

Parameters

bitDataType
The primitive data type to be associated with the elements.

The value of this parameter can be null (Nothing in Visual Basic).

value
The value to be converted to a sequence of bits.
bitCount
The number of bits from the value to be converted.

Valid values of this parameter are in the range from 0 to 2147483647 (Int32.MaxValue).

Return Value

This method never returns null (Nothing in Visual Basic).

Exceptions
ExceptionDescription

The value of an argument is outside the allowable range of values as defined by the invoked method.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks
This method overloads synthesizes a new sequence data type using bitDataType and associates it with the sequence data.
Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
