Qread

Qread is a source-generated data reader implementation rather than using reflection to set properties on your DTOs.

Qread expects that your DTOs are used only for reading data from an IDataReader. Your DTO may be a class, a record, or a struct.

Using Qread is dead simple:

using Qread; ... public sealed partial class MyService { public async Task<IReadOnlyList<Record>> GetRecords() { // Get an IDataReader... var dtos = MyDto.ListFromDataReader(dataReader); // Alternatively, use MyDto.FromDataReader(dataReader) to get a single MyDto. // Map MyDto to Record and return. } [GenerateDataReader] private sealed partial record MyDto { public required Guid Id { get; init; } public required string Name { get; init; } } }

If your DTO properties are in exactly the same order as your SQL select columns you can make Qread even faster by specifying the IsExact property:

[GenerateDataReader(IsExact = true)] private sealed partial record MyDto { ... }
