PTrampert.QueryObjects

NuGet Version

Attribute-based query objects for LINQ/IQueryable in .NET

Overview

PTrampert.QueryObjects is a .NET library that enables you to define query objects using attributes, making it easy to build dynamic, type-safe queries for IQueryable<T> sources. By annotating properties on your query object, you can declaratively specify how each property should filter your data, and then apply the query object to any IQueryable<T> using a simple extension method.

Features

  • Attribute-based query object filtering
  • Supports custom query logic via IQueryObject<T>
  • Works with any IQueryable<T> (e.g. Entity Framework, MongoDB) or IEnumerable<T>

Example Usage

Suppose you have a target class and a query object:

public class Person
{
    public int Age { get; set; }
    public string Name { get; set; } = string.Empty;
}

public class PersonQuery
{
    [EqualsQuery]
    public int? Age { get; set; }

    [StringContainsQuery]
    public string? Name { get; set; }
}

You can use your query object to filter an IQueryable<Person>:

using PTrampert.QueryObjects;

var people = new List<Person>
{
    new Person { Age = 30, Name = "Alice" },
    new Person { Age = 40, Name = "Bob" },
    new Person { Age = 30, Name = "Caroline" }
};

var query = new PersonQuery { Age = 30, Name = "li" };

var filtered = people.Where(query).ToList();
// filtered contains Alice and Caroline
