Asp.net mvc 3 映射ICollection<；字符串>；使用fluentapi

FluentAPI无法基于以下代码创建关系模型：

public class Project
{
    public Guid ID { get; private set; }
    public string Name { get; set; }
    public virtual ICollection<string> Images { get; set; }
}

public class ProjectConfiguration : EntityTypeConfiguration<Project>
{
    public ProjectConfiguration()
    {
        HasKey(p => p.ID)
            .Property(p => p.ID)
                .IsRequired();

        Property(p => p.Name)
            .HasMaxLength(60)
            .IsRequired();

        HasRequired(p => p.Images).WithMany(); //???? Correct ??
        //HasMany(p => p.Images);  //???? Correct ??
    }
}

不支持基元类型集合的映射，它们不是有效的导航属性。您必须定义实体类并使用它，而不是在

集合中使用

字符串

：

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

public class Project
{
    // ...
    public virtual ICollection<Image> Images { get; set; }
}

public IQueryable<Project> GetAll(params Expression<Func<Project, object>>[] includeProperties)
{
    return includeProperties.Aggregate<Expression<Func<Project, object>>,
        IQueryable<Project>>(Context.Projects, (current, includeProperty) => current.Include(includeProperty));
}

public IQueryable<Project> GetAll(int pageIndex, int pageSize, params Expression<Func<Project, object>>[] includeProperties)
{
    return includeProperties.Aggregate<Expression<Func<Project, object>>,
        IQueryable<Project>>(Context.Projects, (current, includeProperty) => current.Include(includeProperty)).OrderBy(p => p.Name).Skip(pageIndex).Take(pageSize);
}

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

public class Project
{
    // ...
    public virtual ICollection<Image> Images { get; set; }
}

public ProjectConfiguration()
{
    // ...
    HasMany(p => p.Images).WithRequired();
    // for a one-to-many relationship
    // it will also setup cascading delete
}
