orm – 实体框架4仅代码从MetaData获取POCO域对象的表名

下面是为了退出Product类的表和模式名称的代码：

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

public class ProductConfiguration : EntityTypeConfiguration<Product>
{
    public ProductConfiguration()
    {
        HasKey(e => e.Id);

        Property(e => e.Id)
            .HasColumnName(typeof(Product).Name + "Id");

        Map(m =>
        {
            m.MapInheritedProperties();
            m.ToTable("ProductsTable");
        });

        Property(p => p.Name)
            .IsRequired()
            .IsUnicode();
    }
}

public class Database : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Configurations.Add(new ProductConfiguration());
    }

    public DbSet<Product> Products { get; set; }
}

现在,要检索Product类的表名,您必须创建DbContext并使用以下代码：

using(var dbContext = new Database())
{
    var adapter = ((IObjectContextAdapter)dbContext).ObjectContext;
    StoreItemCollection storageModel = (StoreItemCollection)adapter.MetadataWorkspace.GetItemCollection(DataSpace.SSpace);
    var containers = storageModel.GetItems<EntityContainer>();

    EntitySetBase productEntitySetBase = containers.SelectMany(c => c.BaseEntitySets.Where(bes => bes.Name == typeof(Product).Name)).First();

    // Here are variables that will hold table and schema name
    string tableName = productEntitySetBase.MetadataProperties.First(p => p.Name == "Table").Value.ToString();
    string schemaName = productEntitySetBase.MetadataProperties.First(p => p.Name == "Schema").
}

我怀疑这是一个完美的解决方案,但正如我之前使用它并且它没有问题.
