c# - Linux 系统在 .NET Core 应用程序上引发错误

Question

我在 .NET Core 中为 Linux 编写了一个控制台应用程序。当我尝试在我的 linux vps 上运行它时，它会抛出该错误:

Could not resolve type with token 01000010
  at Lumo.Program.Main (System.String[] args) [0x00039] in <dff92c70c42444648f6bf1be28aa709c>:0
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not resolve type with token 01000010
  at Lumo.Program.Main (System.String[] args) [0x00039] in <dff92c70c42444648f6bf1be28aa709c>:0

这是我的主要 C# 代码:

string city;
 Console.WriteLine("lolyweather");
  Thread.Sleep(1000);
   Console.Write("Enter your city: ");
   city = Console.ReadLine();
   string link = "https://api.openweathermap.org/data/2.5/weather?q=" + city + "&appid=" + API_KEY + "&units=metric&cnt=6";
 GetWeather(link, city);

这是 GetWeather 函数:

 public static void GetWeather(string url, string city)
        {
            HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
            httpWebRequest.Method = "GET";
            try
            {
                using (WebResponse response = httpWebRequest.GetResponse())
                {
                    HttpWebResponse httpResponse = response as HttpWebResponse;
                    using (StreamReader reader = new StreamReader(httpResponse.GetResponseStream()))
                    {
                        var json = reader.ReadToEnd();
                        var obj = JsonConvert.DeserializeObject<WD.RootObject>(json);
                        WD.RootObject weather = obj;


                        Console.WriteLine("There are " + weather.weather[0].main.ToString() + " in {0}", city);
                        Console.WriteLine("There are {0} \u00B0C.", Math.Round(weather.main.temp));
                        Console.WriteLine("Max temperature: {0}, Minimum temperature: {1}", Math.Round(weather.main.temp_max), Math.Round(weather.main.temp_min));
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Program crashed: {ex.Message} (Check if you wrote your city's name correctly!)");
                Thread.Sleep(1_000);
            }
        }

有人知道怎么回事吗？

从您的上一条评论来看，您似乎构建了 .NET Core 应用程序的依赖于框架的版本。您不能只上传 dll 并在不安装 .NET 运行时或创建自包含部署的情况下执行它。我建议您在 VPS 上安装 .NET 运行时，其中包括复制 dotnet 发布命令的所有输出，或者创建一个独立的部署作为发布步骤的一部分并上传。

尝试此命令并将输出复制到发布文件夹中，并让我们知道它是否有效。

dotnet publish -c Release -r linux-x64 --self-contained true
