我在http://teamcity.codebetter.com/project.html?projectId=project41使用 filehelper 2.9.9将我的数据导出为 CSV 格式。
我使用 [FieldNotInFile] 忽略一些我不想导出的字段。
当我的数据库更改时，我还使用 MetadataType 来避免编辑模型
这是我的代码：

public partial class book
{
    public long id { get; set; }
    public string book { get; set; }
    public virtual author author { get; set; }
}


[MetadataType(typeof(bookMetadata))]
[DelimitedRecord(",")]
public partial class book
{

}

public class bookMetadata
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    [FieldNotInFile] //It don't work at all
    public long id;

    [DisplayName("Book")]
    public string book { get; set; }
    public author author;



    [FieldNotInFile] //It don't work at all
    private author _author;

    public author author
    {
        get { return _author; }
        set { _author = value; }
    }
}

我的问题是当我在元数据中应用 [FieldNotInFile] 属性时，它根本不起作用。
当我将字段封装在由数据库生成的模型中并应用属性时，它可以完美运行。但是，每次数据库更改时，我都必须手动合并它们。

任何帮助表示赞赏
提前感谢

This is probably the limitation of FileHelper (it probably just uses reflection to find attributes on the serialized class and is not aware of metadata buddy class).

Try creating a Model class for it, copy the data using AutoMapper and that apply your attribute to the Model class. Editing generated code is to error-prone, IMHO.
