针对具有C＃中biztalk模式集合的模式的多线程xml验证

Question

我试图使用下面的代码验证架构

 string[] assemblyNameParts = schemaStrongName.Split(new char[] { ',' }, PARTS_IN_SCHEMA_STRONG_NAME);
            string className = assemblyNameParts[PART_CLASS_NAME].Trim();
            string fullyQualifiedAssemblyName = assemblyNameParts[PART_QUALIFIED_ASSEMBLY_NAME].Trim();

            Assembly schemaAssembly = Assembly.Load(fullyQualifiedAssemblyName);
            Type schemaType = schemaAssembly.GetType(className);
            SchemaBase btsSchemaCollection = (SchemaBase)Activator.CreateInstance(schemaType);

            XmlReaderSettings xmlReadeSettings = new XmlReaderSettings();
            //xmlReadeSettings.DtdProcessing = DtdProcessing.Ignore;
            xmlReadeSettings.ValidationType = ValidationType.Schema;
            xmlReadeSettings.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings | XmlSchemaValidationFlags.ProcessIdentityConstraints;// | XmlSchemaValidationFlags.AllowXmlAttributes;
            foreach (XmlSchema xschema in btsSchemaCollection.SchemaCollection)
            {
                String schemaXMl = xschema.ToString();
               xmlReadeSettings.Schemas.Add(xschema);
               //XmlSchema schema = XmlSchema.Read(new StringReader(schemaXMl));//, (sender, args) => { });
            }

            xmlReadeSettings.ValidationEventHandler += new ValidationEventHandler(ValidationHandler);

            XmlTextReader xmlTextReader = new XmlTextReader(new StringReader(requestMessage.OuterXml));
            XmlReader xmlReader = XmlReader.Create(xmlTextReader, xmlReadeSettings);

            while (xmlReader.Read()) ;
            xmlReader.Close();

但我发现XMLSchema不是线程安全的，如下面的链接

所述

Multithreaded xml validation against schema in .net

现在我的问题是如何将模式缓存为btsSchemaCollection.SchemaCollection的字符串

我需要使用下面的代码

 XmlSchema schema = XmlSchema.Read(new StringReader(schemaXml), (sender, args) => { });
            settings.Schemas.Add(schema);

并替换下面的代码

foreach (XmlSchema xschema in btsSchemaCollection.SchemaCollection)
            {
                String schemaXMl = xschema.ToString();
               xmlReadeSettings.Schemas.Add(xschema);
               //XmlSchema schema = XmlSchema.Read(new StringReader(schemaXMl));//, (sender, args) => { });
            }
