在C＃中使用Deedle需要哪些using语句？ “无法加载类型'Deedle.Frame'”异常

如何解决在C＃中使用Deedle需要哪些using语句？ “无法加载类型'Deedle.Frame'”异常

第二次编辑：我找到了一个MS日志查看器，但没有启发我。显示的内容如下：

编辑：我更改了名称空间，但错误消息没有更改。

我有一个非常简短的C＃程序。我正在尝试第一次使用deedle。不幸的是，我在网上找到的所有示例仅显示可执行代码，而顶部则不需要任何using语句。搜索时没有找到解决该问题的页面。这是错误消息。

System.TypeLoadException HResult = 0x80131522 消息=无法从程序集'deedle，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null'中加载类型'deedle.Frame'。 Source = 堆栈跟踪：

这是我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using deedle;

namespace deedleCaller
{
    class Program
    {
        static void Main(string[] args)
        {
            var msftRaw = Frame.ReadCsv(@"C:\Users\afargnoli\Documents\ASRD\Devel\SRFN Data Analytics\link_success_rates\kennett_intervals_jan.csv");
            msftRaw.Print();
            Console.WriteLine("\nPause");
            string unused = Console.ReadLine();
        }
    }
}

解决方法

...Message=Could not load type 'Deedle.Frame' from assembly 'Deedle...

这告诉您，您没有在Nued of Deedle中出现的程序集：https://www.nuget.org/packages/Deedle

而且，正如托马斯所说，如果更改名称空间会更好。即“ DoodleProject”。

通过使用新名称空间创建一个新项目来完成最后一件事，然后下载块，它应该可以正常工作。
