我试图从ICollection中选择一个属性[filename]到一个List中,其中dr405有很多属性.
return GetDR405ById(c,id).dr405files.Select(p => p.FileName).ToList< String>();
public class dr405files
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int FileId { get; set; }
public String TangiblePropertyId { get; set; }
public String FileName { get; set; }
public DateTime? UploadDate { get; set; }
public Byte[] FileData {get;set;}
public long? FileLength { get; set; }
}
我想要SELECT [Column1] FROM [Table1]的sql等价物而不是`SELECT * FROM [Table1]
