问题 my problem is with creating an angular directive. I want to create a group of checkboxes with just one single ng-model. It's like a bitfield or flags, i.e. the checkboxes have values from 0, 1, 2, 3 up to n but for ng-model I just want to add 2^value of all checked checkboxes.

That domaincontrol has a couple of properties and then its own nested list... none of its properties get set, they are all null public class AssetSearchModel { public List<SearchControlModel> SearchControls { get; set;

问题 I'm writing and ASP.NET Core 1 application, which has a Web API Controller where supplier will post data. This is a simplified version of the Model class to which I will bind the incoming data: public class Lead { public int SupplierId { get; set; } public DateTime Date { get; set; } } The problem is that the dates will be posted with German formatting, for instance, 30.09.2016 . I do not want to set the global culture of the application to de-DE because a) I'm not German, and b) the rest of
