区分大小写 Entity Framework 代码优先

Question

我使用 Entity Framework CodeFirst 创建数据库。我看了其他问题，但其中任何一个都没有具体 answer.I 尝试将这两个 KEY 作为不同的行保存到我的 table.:

12E60AED-7491-49B3-8006-78ECEA63B376 12e60aed-7491-49b3-8006-78ecea63b376

这是我的 class 属性：

[AttributeUsage(AttributeTargets.Property, AllowMultiple = true)]
    public class CaseSensitive : Attribute
    {
            public CaseSensitive()
            {
                IsEnabled = true;
            }
            public bool IsEnabled { get; set; }
    }

这是我的数据库模型：

[Table("StandardBusinessDocument", Schema = "EFatura")]
    public class StandardBusinessDocument{
        [Key]
        [Column( TypeName= "varchar" , Order =0), MaxLength(36) ]
        [CaseSensitive]
        public string StandardBusinessDocumentGuid { get; set; }

        [Key]
        [Column(TypeName = "bit", Order = 1)]
        public Boolean StandardBusinessDocumentType { get; set; }

        [Column(TypeName = "varchar"), MaxLength(4)]
        public string Code{ get; set; }
}

这是 entityContex:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Conventions.Add
                (new AttributeToColumnAnnotationConvention<CaseSensitive, bool>
                ("CaseSensitive", (property, attributes) => attributes.Single().IsEnabled));
}

但它不起作用，当我从 tableDesigner-Collation CaseSensitive 中查看 caseSensitive 时，它已被禁用。我该如何操作？

Answer 1

我找到了答案。我在 [Key] 之后写 CaseSensitive 和这项工作。我不知道怎么...:[=11=]

[Key]
[CaseSensitive]
[Column( TypeName= "varchar" , Order =0), MaxLength(36) ]
public string StandardBusinessDocumentGuid { get; set; }
