    Class BitStringArrayHandler

    A special handler for arrays of bit strings. Differs from the standard array handlers in that it returns arrays of bool for BIT(1) and arrays of BitArray otherwise (just like the scalar BitStringHandler does).

    public class BitStringArrayHandler : ArrayHandler<BitArray>
    Remarks

    The type handler API allows customizing Npgsql's behavior in powerful ways. However, although it is public, it should be considered somewhat unstable, and may change in breaking ways, including in non-major releases. Use it at your own risk.

    Constructors

    BitStringArrayHandler(PostgresType, BitStringHandler)

    Declaration
    public BitStringArrayHandler(PostgresType postgresType, BitStringHandler elementHandler)
    Parameters
    Type Name Description
    PostgresType postgresType
    BitStringHandler elementHandler

    Methods

    Read<TAny>(NpgsqlReadBuffer, Int32, Boolean, FieldDescription)

    Reads a value of type TAny with the given length from the provided buffer, using either sync or async I/O.

    Declaration
    protected override async ValueTask<TAny> Read<TAny>(NpgsqlReadBuffer buf, int len, bool async, FieldDescription fieldDescription = null)
    Parameters
    Type Name Description
    NpgsqlReadBuffer buf

    The buffer from which to read.

    Int32 len

    The byte length of the value. The buffer might not contain the full length, requiring I/O to be performed.

    Boolean async

    If I/O is required to read the full length of the value, whether it should be performed synchronously or asynchronously.

    FieldDescription fieldDescription

    Additional PostgreSQL information about the type, such as the length in varchar(30).

    Returns
    Type Description
    ValueTask<TAny>

    The fully-read value.

    Type Parameters
    Name Description
    TAny
    Overrides
    Npgsql.TypeHandlers.ArrayHandler<System.Collections.BitArray>.Read<TAny>(Npgsql.NpgsqlReadBuffer, System.Int32, System.Boolean, Npgsql.BackendMessages.FieldDescription)
