Question

我正在开发xamarin.ios应用程序，它在两个三个月之前运行良好，没有任何问题。但是现在我偶尔会收到以下错误。

“路径上的共享冲突/用户/ vofox3 / Library / Developer / CoreSimulator / Devices / A357B468-BDBA-4397-B2D7-40A6333E93CD / data / Containers / Data / Application / 5D715BAA-DD43-404D-8D94-0E11224745E8 / Documents /WBidMax/User.xml”。

我使用下面的代码来读取User.XML文件。

/// <summary>
      /// Load configuration details from XML
      /// </summary>
      /// <typeparam name="T"></typeparam>
      /// <param name="filePath"></param>
      /// <returns></returns>
      public static T DeserializeFromXml<T>(string filePath)
      {
          try
          {

              T wBidConfiguration;
              using (TextReader configurationFileStream = new StreamReader(filePath))
              {
                  XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
                  wBidConfiguration = (T)xmlSerializer.Deserialize(configurationFileStream);
                  return wBidConfiguration;
              }


          }
          catch (Exception ex)
          {
              throw;
          }
      }

以下用于编写XML文件的代码。

public static bool SerializeToXml<T>(T configType, string filePath)
       {
           bool status = false;
           try
           {
               XmlWriterSettings xmlWriterSettings;
               XmlSerializerNamespaces xmlSerializerNamespaces;

               xmlWriterSettings = new XmlWriterSettings
               {
                   Indent = true,
                   OmitXmlDeclaration = false,
                   NamespaceHandling = NamespaceHandling.OmitDuplicates,
                   Encoding = Encoding.UTF8
                   CloseOutput = true


               };
               xmlSerializerNamespaces = new XmlSerializerNamespaces();
               xmlSerializerNamespaces.Add("", "");

               if (!Directory.Exists(Path.GetDirectoryName(filePath)))
                   Directory.CreateDirectory(Path.GetDirectoryName(filePath));

               using (FileStream configurationFileStream = new FileStream(filePath, FileMode.Create))
               {

                   using (XmlWriter xmlWriter = XmlWriter.Create(configurationFileStream, xmlWriterSettings))
                   {
                       XmlSerializer serializer = new XmlSerializer(typeof(T));
                       serializer.Serialize(xmlWriter, configType, xmlSerializerNamespaces);
                   }
               }

               status = true;
           }
           catch (Exception ex)
           {
               status = false;
           }

           return status;
       }

你能告诉我这个错误的原因吗？

看起来发生了并发文件访问。在写入操作期间锁定文件可能会为您解决此问题。特别是如果您从不同的线程或任务访问该文件。

在c＃中共享路径违规（对于xamarin.ios）
