模型对象验证 (TryValidateModel) 但不更新 (TryUpdateModel)
模型对象拒绝在生产服务器上更新，但在开发计算机上没有问题。出于测试目的，我检索模型对象，然后立即检查其验证和更新状态，例如：
Timesheet timesheet = _timesheetRepository.GetTimesheet(timesheetId);
Helpers.ErrorHandler check = new Helpers.ErrorHandler();
check.write("can I validate immediately? :- ", TryValidateModel(timesheet).ToString());
check.write("can I save immediately? :- ", TryUpdateModel(timesheet).ToString());
TryValidateModel - 返回 true TryUpdateModel - 返回 false
有什么建议吗？
The Model object refuses to update on production server but has no issues on development machine. For the purposes of testing, I retrieve the model object and then immediately check its validation and update states, for example:
Timesheet timesheet = _timesheetRepository.GetTimesheet(timesheetId);
Helpers.ErrorHandler check = new Helpers.ErrorHandler();
check.write("can I validate immediately? :- ", TryValidateModel(timesheet).ToString());
check.write("can I save immediately? :- ", TryUpdateModel(timesheet).ToString());
TryValidateModel - returns true
TryUpdateModel - returns false
Any recommendations?

验证和绑定是不同的。通常可以绑定无效数据（这是一项功能；它使得在出现错误时重新显示页面变得更加容易）和“有效”数据（根据您的验证规则，如果有的话）有时由于打字冲突而无法绑定。
Validation and binding are different. Invalid data can often be bound (this is a feature; it makes re-displaying a page in the case of an error much easier), and "valid" (per your validation rules, if any) data sometimes can't be bound, due to typing conflicts.
