[英]C# Model validation throws “Cannot convert from System.DateTime to System.Array”
I'm trying to insert to a table from excel using LinqToExcel and when I call 我正在尝试使用LinqToExcel从excel插入到表中,当我调用时
ValidateModel(u);
It throws an exception: 它引发了一个异常:
Cannot convert from System.DateTime to System.Array
无法从System.DateTime转换为System.Array
I'm using DataAnnotations on the viewmodel. 我在viewmodel上使用DataAnnotations。
Datetime in ViewModel: ViewModel中的日期时间:
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
public DateTime FECHA_ADQ { get; set; }
Controller: 控制器:
foreach (var a in excel.Worksheet<ViewModel>(sheet.First()))
{
//Validations//
try
{
Context db = new Context();
ViewModel u = a;
ModelState.Clear();
ValidateModel(u);
//Insert//
}
catch(Exception)
{
// ...
}
}
Datetime in excel file: excel文件中的日期时间:
This is what it looks like on the debugger: 这是它在调试器上的样子:
I couldn't resolve the issue with excel so i just ended up validating after the mapping to the base model and it worked. 我无法用excel解决这个问题,所以我最终在映射到基本模型后验证并且它工作正常。
ModelState.Clear();
var config = new MapperConfiguration(cfg => {
cfg.CreateMap<ViewModel, Model>();
});
IMapper mapper = config.CreateMapper();
var inv = mapper.Map<ViewModel, Model>(u);
if (inv.FECHA_ADQ.Year <= 2005) {
errors.AppendLine("Serial: " + a.SERIAL + " Error on Row: " + row + " Cause: Invalid Date.");
counter++;
} else {
ValidateModel(inv);
Context.ModelDB.Add(inv);
Context.SaveChanges();
}
