问题 I have a post method that sends json to my api. My endpoint works in postman so my problem is in my xamarin post request: async void RegisterUser(object sender, System.EventArgs e) { string URL = "http://blablahblah:51001/register"; HttpClient client = new HttpClient(); var model = new RegisterViewModel { Email = EntryEmail.Text, FirstName = FirstName.Text, LastName = LastName.Text, Password = EntryPasswrd.Text }; var content = JsonConvert.SerializeObject(model); await client.PostAsync(URL,

问题 I'm making a tree structure. As a result, I want to receive such a structure: [ { name: 'node1', subNodes: [ { name: 'node1-1', subNodes: [], }, { name: 'node1-2', subNodes: [], }, ], }, { name: 'node2', subNodes: [], }, { name: 'node3', subNodes: [ { name: 'node3-1', subNodes: [ { name: 'node3-1-1', subNodes: [], }, { name: 'node3-1-2', subNodes: [], }, ], }, { name: 'node3-2', subNodes: [], } ], }, ]; To do this I created a Api endpoint: [HttpGet] public async Task<IActionResult> GetTree()

问题 Technology stack : One REST API developed in .Net Core 3.1. Two client apps one in Android and other in iOS Scenario : Store enum value in the database such that when the data is uploaded to the API it makes sense (API can take decisions based on the enum). Option 1 : Store enum as a number and copy it in the API. In this scenario, the enum value would be saved in the DB and transferred to the API. When the API need to use the enum for a condition or some other use, it would use the copy of

问题 I have referenced the .Net framework ddl to .Net standard 2.0 . It will show me below errors. System.Reflection.ReflectionTypeLoadException: 'Unable to load one or more of the requested types.

问题 In VS 2015, for my Web.API project, I installed MVC 5 from nuget via npm. This installation added references and generated web.config file under Views folder. I added new Controller with generated CRUD functions. When I right click and go to View on action it goes with no problem. But reverse action does not work. If I navigate to view via browser it works as well. Web app compiles as well. Is there any way for me to fix this navigation problem in VS? Did I forget to add something? Following

问题 I am converting from .NET CORE 2.2 to 3.1. Is it possible to force the controller to use System.Text.Json to serialize and deserialize any incoming request and response? Basically, when the request comes in I want to use System.Text.Json and when a response goes out I want to use System.Text.Json . If yes, how? The reason for doing this is that Microsoft is really pushing this library as the replacement for Newtonsoft.Json as being so much safer and faster. But, I cannot seem to find any

问题 I'm trying to access a query string parameter that was sent using the POST method (WebClient) to the Web API in ASP.NET MVC 5 (in an overridden AuthorizationFilterAttribute). For Get, I've used the following trick: var param= actionContext.Request.GetQueryNameValuePairs().SingleOrDefault(x => x.Key.Equals("param")).Value; However, once I use POST, this does work and the variable paran is set to null. I think that's because the query string method only applies to the url, not the body. Is
