如何删除级联EF核

// 定义实体类
public class Category
{
    public int Id { get; set; }
    public string Name { get; set; }
    public List<Product> Products { get; set; }
}

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

// 在DbContext中配置关系
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Category>()
        .HasMany(c => c.Products)
        .WithOne(p => p.Category)
        .OnDelete(DeleteBehavior.Cascade);
}

// 执行删除操作
using (var context = new YourDbContext())
{
    var category = context.Categories.FirstOrDefault(c => c.Id == categoryId);
    if (category != null)
    {
        context.Remove(category);
        context.SaveChanges();
    }
}
