// Assume we have the following DbContext and entity class:
// public class MyDbContext : DbContext { public DbSet<Product> Products { get; set; } }
// public class Product { public int Id { get; set; } public string Sku { get; set; } }

// Get a list of all products from the database
using (var db = new MyDbContext())
{
    var products = db.Products.ToList();
    
    // Loop through each product and split its SKU into an array
    foreach (var product in products)
    {
        var skuParts = product.Sku.Split('/');

        // Loop through each part of the SKU and save it to the database as a new product
        foreach (var skuPart in skuParts)
        {
            db.Products.Add(new Product { Sku = skuPart });
        }

    db.SaveChanges();

// Send an email complaining about the splitting operation
