c# - 序列化 View 模型时出错 : "Type ' System. Web.HttpPostedFileWrapper' 无法序列化。”

Question

这是我的 View 模型:

[Serializable]
public class MyViewModel
{
    public int VendorId { get; set; }

    public HttpPostedFileBase SpreadsheetFile { get; set; }       

    public IEnumerable<Vendor> Vendors { get; set; }        
}

我正在用数据加载我的 View 模型并将其传递给 View 并序列化它:

@Html.Serialize("MyModel", myViewModel)

但是我收到了这个错误

Type 'System.Web.HttpPostedFileWrapper' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.

我不确定如何使用 DataContractAttribute 标记某些内容。有没有办法将 HttpPostedFileBase 属性标记为不可序列化？

Answer 1

尝试标记它 NonSerialized .

[Serializable]
public class MyViewModel
{
    public int VendorId { get; set; }

    [NonSerialized]
    public HttpPostedFileBase SpreadsheetFile { get; set; }       

    public IEnumerable<Vendor> Vendors { get; set; }        
}
