问题 I'm using .NET Core 2.0. I have a POST action on my controller. It binds the data from the body of the request (JSON) into a C# DTO. On the DTO I have validation attributes - for instance: [Required] [MaxLength(512)] public string email { get; set; } These validators execute in the order that they are defined on the property. I would like to short-circuit the validation if a prior validator fails. For example - if the required validation fails, don't execute the max length validation. Is

问题 Razor Pages do not need any AreaAttribute and it is enough to place them into Areas/MyArea/Pages folder and this is enough to enable routing /MyArea/MyPage + My Proj + Areas + MyArea + Pages - MyPage.cshtml But when if I put API Controlller MyApi.cs to MyArea folder: + My Proj + Areas + MyArea + Pages - MyApi.cs then I am become forced to "hardcode" area name [Area("MyArea")] // !!! can't be missed [Route("[area]/api/[action]")] [Produces("application/json")] [ApiController] public class

[HttpPost] [Route("api/createstudent")] public async Task<ActionResult> CreateStudent([FromBody]Student student) { // Service logic } Model: public class Student { public Guid StudentId { get; set; } public string StudentName { get; set; } } My problem is that

问题 I have created an .NET Core API project. It works but it creates a new object for each get request. Where can I save the object so that I can reuse it? I have searched Google and found Session but that only seems to store bytes or serialised bytes. I don't think I can serialise the object. If doSomeInitialisation() takes 1 seconds, creating a new SomeLibrary at each get request when the arg1 is the same does not seem efficient and SomeLibrary is not serialisable so it cannot be stored to the

I know one way to achieve by calling method on client is in AXIOS interceptor like below. httpPromise.interceptors.response.use(undefined, err => { const { config, response

问题 I'm using the Kendo Upload control in an Angular app and it's 99% working, but it seems to be adding a small piece of text to the start of the text file I'm uploading.

问题 I have an enum such as public enum SampleFormats { unknown = 0, audio = 1, video = 2, } Is it possible to decorate the unknown member in a way that it is excluded by the generated swagger json? I could possibly write a schema/document filter, but was wondering if there was something out of the box. 回答1: You can try this: public enum SampleFormats { unknown = 0, audio = 1, video = 2, } public class ResultModel { public SampleFormats Format { get; set; } [JsonIgnore] public bool FormatSpecified
