试图让我的.net核心应用程序在Visual Studio代码中运行

Question

我的Windows硬盘驱动器最近有点尘土飞扬，最近我在使用.net core 1.1的vs 2015中开发了一个有角度的2 .net core应用程序。 我有一台装有ubuntu的计算机，所以我虽然不为什么不下载VS代码并克隆我的项目并开始正确工作.....好吧，我遇到了问题，希望有人可以提供帮助。

我安装c＃我安装C＃扩展。 但这是我得到的错误

建立失败。 /home/deshazer/Documents/code/HannaOilGas2/HannaOilAndGas2/project.json(1,1）：错误MSB4025：无法加载项目文件。 根级别的数据无效。 第1行，位置1。0警告1错误经过的时间00：00：00.06

现在我的project.json文件看起来像这样

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.1.0",
      "type": "platform"
    },

  },

  "tooling": {
    "defaultNamespace": "HannaOilAndGas2"
  }
}

我还在模型和控制器中发现问题，我在使用Web API，有人可以在vs代码中为我提供帮助吗？

using System;
using System.Collections.Generic;

namespace HannaOilAndGas2.Data
{
    public partial class MainView
    {
        public int RecId { get; set; }
        public string Location { get; set; }
        public double? SpotFlowRate { get; set; }
        public double? PreviousDayVolume { get; set; }
        public double? LinePressure { get; set; }
        public double? DifferentialPressure { get; set; }
        public double? Temperature { get; set; }
        public double? BatteryVoltage { get; set; }
        public double? Fcp { get; set; }
        public double? Ftp { get; set; }
        public DateTime? Timestamp { get; set; }
        public string LastCommunicationMethod { get; set; }
        public string MeterId { get; set; }
        public string ImportMethod { get; set; }
        public int HannaDeviceId { get; set; }


    }
}

说找不到类型系统，它要求我将int放入方法eh。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using HannaOilAndGas2.Data;

    [Produces("application/json")]
    [Route("api/mainview")]
    public class MainViewApi : Controller
    {
        private readonly ScadaContext _context;

        public MainViewApi(ScadaContext context)
        {
            _context = context;
        }
        // GET: api/values
        [HttpGet]
        [Route("allmainview")]          //front end - done
        public IEnumerable<MainView> GetAllMainView()
        {
            return _context.Main_View.Where(x => !x.MeterId.StartsWith("HOGC"));            
        }

        [HttpGet]
        [Route("allwinccuview")]        //front end - done
        public IEnumerable<MainView> GetAllWinccuView()
        {
            return _context.Main_View.Where(x => x.ImportMethod == "WINCCU" );
        }

        [HttpGet]
        [Route("allmanualview")]        //front end - done
        public IEnumerable<MainView> GetAllManualView()
        {
            return _context.Main_View.Where(x => x.ImportMethod == "SPREADSHEET");
        }

        [HttpGet]
        [Route("allservicestarview")]   //front end - done
        public IEnumerable<MainView> GetAllServiceStarView()
        {
            return _context.Main_View.Where(x => x.ImportMethod == "SERVICESTAR-POLL");
        }

        {
            return _context.Main_View.Where(x => x.MeterId.StartsWith("HOGC"));
        }

        // GET api/values/5
        [HttpGet("{id}")]
        public IEnumerable<MainView> GetMainViewDataById(int id)
        {
            return _context.Main_View.Where(x => x.RecId == id);
        }

        // POST api/values
        [HttpPost]
        public void Post([FromBody]string value)
        {
        }

        // PUT api/values/5
        [HttpPut("{id}")]
        public void Put(int id, [FromBody]string value)
        {
        }

        // DELETE api/values/5
        [HttpDelete("{id}")]
        public void Delete(int id)
        {
        }
    }
}

这就是说未定义预定义类型的系统字符串或再次在我的project.json中导入了netcoreapp1.1，请提供任何帮助。

Answer 1

Project.json更改回.csproj。 我建议您使用

dotnet migration命令

在Linux中运行时在CLI中。
