Question

我正在关注教程how-to-use-highcharts-js-with-asp-net-mvc-4

当我构建应用程序时，我收到错误

找不到类型或命名空间名称'DotNet'（您是否缺少using指令或汇编引用？）

我在我的控制器中

using HighChart.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DotNet.Highcharts;
using DotNet.Highcharts.Helpers;
using DotNet.Highcharts.Options;
using DotNet.Highcharts.Enums;

在这一点上，DotNet下面有一个蓝色波浪形。以及我的参考文件夹中的参考“DotNet.Highcharts”。

我正在使用VS 2012专业版（如果重要的话）

我是否需要在我的webconfig中添加一些我缺少的东西，或者我是否需要设置参考路径？我以前使用过nuget包而没有遇到过这个问题所以不确定我需要做什么。

我做了什么。

重新启动VS
关闭/重新开启项目
从头开始项目（mvc 4为空）并添加到nuget的DotNet.Highcharts和Jquery包中，并按照上面列出的教程进行操作。

模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace HighChart.Models
{
    public class TransactionCount
    {
        public string MonthName { get; set; }
        public int Count { get; set; }
    }
}

            //instanciate an object o the highcharts type

            })

                new Series {Name = "Hour", Data = new Data(yDataCounts)},
                //you can add more y data to create a second line
                // new series { Name = "Other Name", Data = new Data(OtherData)}
            });
            return View(chart);

Answer 1

您是否在引用中添加了dll？您需要通过浏览到dll位置手动执行此操作。

Answer 2

在我的情况下，我不得不专门下载“Net 4.0”DLL。 https://dotnethighcharts.codeplex.com/releases/view/121251

老实说，我认为nuget包会处理这个

DotNet.Highcharts包问题
