Question

我编写了一个XML库但是我无法弄清楚为什么我不能阅读我PC上的XML文件。我有大约1.5M的XML文件来解析并转换为SQL。这是我的代码：

    class XMLConverter
        {
            public string XMLConverterSQL(int ID, string lang)
            {
                // int i = ID; // Starting Elements
                Stopwatch stopwatch = new Stopwatch();

                XmlDocument xml;
                XmlElement element;
                XmlNodeList nodes;
                string result;

                //Console.WriteLine(id_min);
                //Console.WriteLine(id_max);
                result = "";
                xml = new XmlDocument();
                xml.LoadXml("C:\\Users\\Phil1\\Desktop\\V1\\XMLDownloader\\bin\\Debug\\XMLData\\" + lang + "\\" + ID + ".xml");
                element = xml.DocumentElement;
                nodes = element.SelectNodes("/wowhead");
                if (xml.SelectSingleNode("/wowhead/error") != null)
                {
                    Console.WriteLine("Item ID {0} does not exist yet or not in WoWHead Database ", ID);
                }
                else
                {
                result += "INSERT INTO item_wh (entry, class, subclass, displayId, ,quality, name, level) VALUES (";
                foreach (XmlNode node in nodes)
                {
                    // entry
                    result += node["item"].Attributes["id"].InnerText;
                    result += ", ";
                    // class
                    result += node["item"]["class"].Attributes["id"].InnerText;
                    result += ", ";
                    // subclass
                    result += node["item"]["subclass"].Attributes["id"].InnerText;
                    result += ", ";
                    // displayId
                    result += node["item"]["icon"].Attributes["displayId"].InnerText;
                    result += ", ";
                    // quality
                    result += node["item"]["quality"].Attributes["id"].InnerText;
                    result += ", \"";
                    // name
                    result += node["item"]["name"].InnerText;
                    result += "\", ";
                    // level
                    result += node["item"]["level"].InnerText;
                    result += ");";
                    // bakcline
                    result += "\r\n";
                    }
                }
                return (result);
            }
        }

主要：

int min = int.Parse(txtMin_ID.Text);
int max = int.Parse(txtMax_ID.Text);
                List<string> results;

                results = new List<string>();
                // ParseXML.CreateDictionary("en");
                // ParseWH.startParse(min, max);  
                var sTab = new ConcurrentBag<int>(Enumerable.Range(min, max + 1));
                Parallel.ForEach(sTab, (i) =>
                {
                    Task.Factory.StartNew(() =>
                    {
                        string Convert = new XMLConverter().XMLConverterSQL(i, "EN");
                        lock (results)
                        {
                            results.Add(Convert);
                        }
                    });
                });
                Task.WaitAny();
                File.WriteAllText("C:\\Users\\Phil1\\Desktop\\result.sql", String.Join("", results));

and here is an example of XML if have to read

为了获得更快的性能我试图将所有XML加载到ConcurrentDictionary中，但是我的内存运行速度非常快，所有XML文件各约为1到9 KB。

我收到了

根级别的数据无效。第1行第1位

但是，对于断点，

错误似乎正确地认为是XML转换器代码

没关系，删除任务工厂

解决了这个问题

var sTab = new ConcurrentBag<int>(Enumerable.Range(min, max));
Parallel.ForEach(sTab, (i) =>
            {
                string Convert = new XMLConverter().XMLConverterSQL(i, "EN");
                lock (results)
                {
                    results.Add(Convert);
                }
            });

XML转SQL转换器c＃
