实体框架代码优先：如何指定索引名称

Question

I'm using code first to generate my database. I will also be using Full Text for searching. However, I cant create the full text index programatically because the primary key index name given by EF is random. Is there a way to explicitly set this?

For example, I have an Items class like below:

public class Item
{

    public string ItemId { get; set; }
    public string ShortName { get; set; }
    public decimal Price { get; set; }
    public string Description { get; set; }
    public string ImageUri { get; set; }
    public string Tags { get; set; }

    public int CategoryId { get; set; }
    public string LastModifiedBy { get; set; }

    public virtual User LastModifiedBy { get; set; }
    public virtual ItemCategory Category { get; set; }
    public virtual ICollection<ItemMetaDataValue> MetaData{get;set;}
    public virtual ICollection<PriceHistoryLog> PriceHistory { get; set; }
}

Now I want to EF to create a full text catalog for the Tags property so I would call something like this using the DbContext.SqlCommand() method.

CREATE FULLTEXT CATALOG [DEFAULT]WITH ACCENT_SENSITIVITY = OFF
AS DEFAULT
AUTHORIZATION [dbo]

CREATE FULLTEXT INDEX ON [dbo].[Items] KEY INDEX [PK__Items__727E838B07020F21] ON ([DEFAULT]) WITH (CHANGE_TRACKING AUTO)

ALTER FULLTEXT INDEX ON [dbo].[Items] ADD ([Tags])

ALTER FULLTEXT INDEX ON [dbo].[Items] ENABLE

However, as you might notice, the primary key index name is not what I expect it to be: PK_ Items _727E838B07020F21. Is there anyway to explicitly specify this key?

Thanks.

Answer 1

Try using [Key] attribute ?

using System.ComponentModel.DataAnnotations;

[Key]
public string ItemId { get; set; }

Answer 2

EF不提供任何指定密钥名称的可能性，更不用说索引名称了。
