对于那么多参数，我可能使用一个类 - 我可能会创建一个包含option，optionImage，optionImageFileExtension和clearOptionImage的类，并使用 params 来传递它们中的一些：

For that many parameters, I'd probably use a class - and I'd probably create one which held option, optionImage, optionImageFileExtension, and clearOptionImage, and use params to pass a number of them through:

public int UpdateMC(Guid Id, string description, decimal score, int optionAnswer, params MyClass[] options)

如果有些需要所有参数，我可能会创建一个类全部保留：

And if some need all of the parameters, I'd probably create a class that held them all:

public class MyParameterClass
   {
         public string description {get; set;}
         public decimal score {get; set;}
         public int optionAnswer {get; set;}
         public bool allowUploadAttachment {get; set;}
         public byte[] image{get; set;}
         public string imageFileExtension {get; set;}
         public bool clearImage {get; set;}
         public byte[] attachment {get; set;}
         public string attachmentFileExtension {get; set;}
         public bool clearAttachment {get; set;}
         public List<MyClass> options {get; set;}
   }
