问题 In a simple controller action in ASP.NET Core 3.1 that accepts multipart/form-data parameters: using System.ComponentModel.DataAnnotations; using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; namespace WebApplication { public class Controller : ControllerBase { [HttpPost("length")] public IActionResult Post([FromForm] Input input) { if (!ModelState.IsValid) return new BadRequestObjectResult(ModelState); return Ok(input.File.Length); } public class Input { [Required] public

问题 I have a WCF connected service in a .net core application. I'm using the code that is autogenerated taken the wsdl definition. Currently at the top of the request xml is including this line: <?xml version="1.0" encoding="utf-16"?> I can't find a simple way to change this encoding to UTF-8 when sending the request. Since I could find a configuration option a the request/client objects, I've tried to change the message with following code at IClientMessageInspector.BeforeSendRequest public

问题 We have a commercial library that I am working to port to .NET Core. There are a couple of calls in it I want to retain to use only if running in .NET standard. (For the curious, one set is to read a file on a Windows server that requires credentials to access.) Is there: A call that will tell me if I am running under .NET Standard vs. .NET Core. Is there a way to have a class that is only going to be instantiated/called if running under standard, but the DLL will still load fine under Core?

问题 We have a ASP.NET Core system and we need to connect to another webservice using SOAP (we received the WSDL from the customer). In the past, we should have use the "add service reference" using WCF options in Visual Studio. For dotnet core projects, the options is no more available but there are several options to get the same solutions: Use SvcUtil in the command line or install the plugin here https://blogs.msdn.microsoft.com/webdev/2016/06/26/wcf-connected-service-for-net-core-1-0-0-and

问题 How can I localize the following enum entries on asp.net core? I found few issues on asp.net-core github repository ( https://github.com/aspnet/Mvc/pull/5185 ), but I can't find a proper way to do it.

问题 I have a DbContext where I would like to run a query to return only specific columns, to avoid fetching all the data. The problem is that I would like to specify the column names with a set of strings, and I would like to obtain an IQueryable of the original type, i.e. without constructing an anonymous type. Here is an example: // Install-Package Microsoft.AspNetCore.All // Install-Package Microsoft.EntityFrameworkCore using Microsoft.EntityFrameworkCore; using System; using System.Linq;

问题 I have a netcore application depends on my custom project. Because I cannot reference it directly, I have written postbuildevents that are copying my files to output: xcopy "$(SolutionDir)Ethereum.Contracts\bin\$(ConfigurationName)\*.abi" "$(TargetDir)" /Y /I xcopy "$(SolutionDir)Ethereum.Contracts\bin\$(ConfigurationName)\*.bin" "$(TargetDir)" /Y /I It works fine when I build and run project, but when run publish command it doesn't include these files. How can it be done? I tried this
