Gets or sets the value of the specified section or bit flag.

Gets or sets the value stored in the specified BitVector32.Section.

property int default[System::Collections::Specialized::BitVector32::Section] { int get(System::Collections::Specialized::BitVector32::Section section); void set(System::Collections::Specialized::BitVector32::Section section, int value); };public int this[System.Collections.Specialized.BitVector32.Section section] { get; set; }member this.Item(System.Collections.Specialized.BitVector32.Section) : int with get, setDefault Public Property Item(section As BitVector32.Section) As IntegerParameters
- section
- BitVector32.Section
A BitVector32.Section that contains the value to get or set.
Property Value
The value stored in the specified BitVector32.Section.
Remarks
The Item[] [Section] property is the indexer for a BitVector32 that is set up as sections, and the Item[] [int] property is the indexer for a BitVector32 that is set up as bit flags.
A BitVector32.Section is a window into the BitVector32 and is composed of the smallest number of consecutive bits that can contain the maximum value specified in CreateSection. For example, a section with a maximum value of 1 is composed of only one bit, whereas a section with a maximum value of 5 is composed of three bits. You can create a BitVector32.Section with a maximum value of 1 to serve as a Boolean, thereby allowing you to store integers and Booleans in the same BitVector32.
The C# language uses the this keyword to define the indexers instead of implementing the Item[] property. Visual Basic implements Item[] as a default property, which provides the same indexing functionality.
Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.

Gets or sets the state of the bit flag indicated by the specified mask.
public:
property bool default[int] { bool get(int bit); void set(int bit, bool value); };public bool this[int bit] { get; set; }member this.Item(int) : bool with get, setDefault Public Property Item(bit As Integer) As BooleanParameters
- bit
- Int32
A mask that indicates the bit to get or set.
Property Value
true if the specified bit flag is on (1); otherwise, false.
Remarks
The Item[] [Section] property is the indexer for a BitVector32 that is set up as sections, and the Item[] [int] property is the indexer for a BitVector32 that is set up as bit flags.
Using this property on a BitVector32 that is set up as sections might cause unexpected results.
