AutoSorter

Easy collection sorting on Attributes

Example

Old way

Imagine, you have CRM-like webapp with availability to sort through fields of customers.

Let's assume you have model like this:

public class Customer
{
  public int Id { get; set; }
  public string Name { get; set; }
  public byte Age { get; set; }
  public bool IsDeleted { get; set; }
}

The basic implementation of data sorting will look smth like this:

public class CustomerController
{
  public async Task<List<Customer>> GetCustomers(int sortingValue, bool sortByDesc) 
  {
    var customers = await _db.GetCustomers();
  
    switch(sortingValue) 
    {
      case 0: sortByDesc ? customers.OrderByDescending(c => c.Id) : customers.OrderBy(c => c.Id); break;
      case 1: sortByDesc ? customers.OrderByDescending(c => c.Name) : customers.OrderBy(c => c.Name); break;
      case 2: sortByDesc ? customers.OrderByDescending(c => c.Age) : customers.OrderBy(c => c.Age); break;
      case 3: sortByDesc ? customers.OrderByDescending(c => c.IsDeleted) : customers.OrderBy(c => c.IsDeleted); break;
      // more redurant cases....
    }
    
    return customers;
  }
}

New way

With AutoSorter there is new, simpler way to do sorting by fields logic. Firsty, assign attributes:

using AutoSorting.Attributes;

public class Customer
{
  [AutoSort(0)]
  public int Id { get; set; }
  [AutoSort(1)]
  public string Name { get; set; }
  [AutoSort(2)]
  public byte Age { get; set; }
  [AutoSort(3)]
  public bool IsDeleted { get; set; }
}

Now you can sort with one simple method call:

using AutoSorter;

public class CustomerController
{
  public async Task<List<Customer>> GetCustomers(int sortingValue, bool sortByDesc) 
  {
    var customers = await _db.GetCustomers();
    
    customers = AutoSorter.Sort(customers, sortingValue, sortByDesc); // That's all!
    
    return customers;
  }
}
