当query调用AsEnumerable时，如何使oData不区分大小写？

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.OData.Edm;
using Microsoft.OData.Query;

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class ProductService
{
    private List<Product> products = new List<Product>
    {
        new Product { Id = 1, Name = "Apple" },
        new Product { Id = 2, Name = "banana" },
        new Product { Id = 3, Name = "Cherry" }
    };

    public IEnumerable<Product> GetProducts(string query)
    {
        var lowerCaseQuery = query.ToLower();
        return products.AsEnumerable()
            .Where(p => p.Name.ToLower().Contains(lowerCaseQuery));
    }
}

class Program
{
    static void Main()
    {
        var productService = new ProductService();
        var results = productService.GetProducts("apple");
        foreach (var product in results)
        {
            Console.WriteLine(product.Name);
        }
    }
}
