Class ScalarTypeAttribute

Namespace

LinqToDB.Mapping

Assembly

linq2db.dll

Overrides default scalar detection for target class or structure. By default linq2db treats primitives and structs as scalar types. This attribute allows you to mark class or struct as scalar type or mark struct as non-scalar type. Also see IsStructIsScalarType. Note that if you marks some type as scalar, you will need to define custom mapping logic between object of that type and data parameter using SetConvertExpression(Type, Type, LambdaExpression, bool, ConversionType) methods.
