The remote server returned an error: (500) Internal Server Error on website

Question

我通过 http://datalan.aspone.cz/ 访问运行网站时遇到问题，红色 table 中的数据仍然不可用，结果返回以下错误消息 “错误关闭远程服务器返回错误：(500) 内部服务器错误。"

此外，网站已经运行在本地主机上，没有问题。

我不知道我哪里错了，但如果有人能帮助解决这些问题，我将不胜感激。

我附上下面的代码：

public List<Data> Generate()
    {
        List<Data> data = new List<Data>();

        WebRequest request = WebRequest.Create("http://192.168.1.100/st0.xml");

        request.Credentials = new System.Net.NetworkCredential("admin", "admin");

        WebResponse response;
        Stream ReceiveStream;
        XmlTextReader reader = null;

        try
        {
            response = request.GetResponse();
            ReceiveStream = response.GetResponseStream();
            reader = new XmlTextReader(ReceiveStream);
        }
        catch (WebException ex)
        {
            response = ex.Response;
            ReceiveStream = response.GetResponseStream();
        }

        List<Tuple<string, string, int>> values = new List<Tuple<string, string, int>>();

        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {
                switch (reader.Name)
                {
                    case "ia0":
                        double temp = Convert.ToDouble(reader.ReadString()) / 10;
                        values.Add(new Tuple<string, string, int>(String.Format(temp.ToString() + " °C"), "Temperature", 0));
                        break;
                    case "ia1":
                        double vol = Convert.ToDouble(reader.ReadString()) / 10;
                        values.Add(new Tuple<string, string, int>(String.Format(vol.ToString() + "V"), "Voltage", 1));
                        break;
                    case "di0":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD0", 2));
                        break;
                    case "di1":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD1", 3));
                        break;
                    case "di2":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD2", 4));
                        break;
                    case "di3":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "INPD3", 5));
                        break;
                    case "out0":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT0", 6));
                        break;
                    case "out1":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT1", 7));
                        break;
                    case "out2":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT2", 8));
                        break;
                    case "out3":
                        values.Add(new Tuple<string, string, int>(reader.ReadString(), "OUT3", 9));
                        break;
                }
            }
        }

        for (int i = 0; i < values.Count; i++)
        {
            for (int j = 0; j < values.Count; j++)
            {
                if (i == values[j].Item3)
                {
                    data.AddRange(new List<Data> { new Data { Type = values[j].Item2, Value = values[j].Item1 } });
                }
            }
        }

        return data;
    }

很可能与这段代码有关：

WebRequest request = WebRequest.Create("http://192.168.1.100/st0.xml");

您正在调用一个本地 IP 地址，如果它是在共享主机上，它可能不会喜欢这个请求。

Answer 2

我已经解决了这些问题。

找到解决方案后，我通过以下步骤编辑了 Web.config 中的代码：

<location path="." inheritInChildApplications="false">  
<system.web>  
...
...
...   
</system.web>  
</location>

下次可以帮到别人。
