Method Description
CopyValueInternal ( int record, object store, BitArray nullbits, int storeIndex ) : void
DetermineIfValueType ( StorageType typeCode, Type dataType ) : bool
GetEmptyStorageInternal ( int recordCount ) : object
GetQualifiedName ( Type type ) : string

wrapper around Type.AssemblyQualifiedName
GetStorageType ( Type dataType ) : StorageType
GetType ( string value ) : Type

wrapper around Type.GetType

Types like "System.Guid" will load regardless of AssemblyQualifiedName because they are special Types like "System.Data.SqlTypes.SqlString" will load because they are in the same assembly as this code Types like "System.Numerics.BigInteger" won't load because they are not special and not same assembly as this code
