我需要關聯表來實現InspChars和材質之間的M:M關係,但應該有一個額外的字段。這就是爲什麼我創建另一個表InspCharsToMaterials。 一切正常,但是,如果創建了自己生成的自動生成的關聯表,我根本不需要它。如何禁止自動創建關聯表EF
如何應對?如何關閉ef的這種可能性(僅適用於多對多)。
[Table("tbl_Materials")]
public class Material
{
[Key]
public int key { get; set; }
[Required]
[Column(TypeName = "NVARCHAR")]
[StringLength(18)]
public string MaterialID { get; set; }
[Required]
[Column(TypeName = "NVARCHAR")]
[StringLength(128)]
public string MaterialName { get; set; }
[Column(TypeName = "bit")]
public bool Deleted { get; set; }
public virtual ICollection<InspectionCharacteristic> InspCharLinks { get; set; }
}
[Table("tbl_InspectionCharacteristic")]
public class InspectionCharacteristic
{
[Key]
[Required]
public int key { get; set; }
[Required]
[Column(TypeName = "NVARCHAR")]
[StringLength(40)]
public string InspCharID { get; set; }
[Required]
[Column(TypeName = "NVARCHAR")]
[StringLength(40)]
public string InspCharName { get; set; }
[Column(TypeName ="BIT")]
public bool IsCatalogType { get; set; }
/*[Column(TypeName = "NVARCHAR")]
[StringLength(8)]
public string CatalogGroupLink { get; set; }*/
[Column("CatalogGroupID")]
public int? CatalogGroupKeyID { get; set; }
//public virtual CatalogGroup CatalogGroup { get; set; }
public virtual ICollection<Material> Materials { get; set; }
}
我的關聯表:
[Table("tbl_InspCharToMaterials")]
public class InspCharToMaterial
{
[Key]
public int key { get; set; }
public virtual Material Material { get; set; }
public virtual InspectionCharacteristic InspectionCharacteristic { get; set; }
public bool Deleted { get; set; }
}
可能的重複[首先創建代碼,多對多,關聯表中有附加字段](http://stackoverflow.com/questions/7050404/create-code-first-many-to-many-with-additional -fields-在關聯表) –
