OpenXml开发-验证OpenXml文件

采用程序自动生成文件的方式时，偶尔会遇到文件不合法的情况，所以最好对生成的文件验证一下，
下面是一个简单的验证程序（是从一个例子里看到的）：

        static void ValidateOpenXMLFile(byte[] data, XmlSchemaSet schemas)
        {
            using (PackageHelper package = new PackageHelper(data))
            {
                foreach (PackagePartHelper part in package.GetItems())
                {
                    Console.WriteLine("Validating part {0}", part.PartName);
                    XmlReaderSettings settings = new XmlReaderSettings();
                    settings.Schemas.Add(schemas);
                    settings.ValidationType = ValidationType.Schema;
                    settings.ValidationEventHandler += DisplayValidationError;
                    using (XmlReader reader = XmlReader.Create(part.GetStream()))
                    {
                        while (reader.Read()) ;
                    }
                }
            }
        }

        static void DisplayValidationError(object sender, ValidationEventArgs e)
        {
            Console.Error.WriteLine("Validation error: {0}", e.Message);
        }

   class SchemaLoader
        {
        public static XmlSchemaSet LoadWordProcessingMLSchemas()
        {
            return CreateSchemaSet(
                "..//..//..//Schemas//wml.xsd");
        }

        public static XmlSchemaSet LoadSpreadsheetMLSchemas()
        {
            return CreateSchemaSet(
                "..//..//..//Schemas//sml-workbook.xsd",
                "..//..//..//Schemas//sml-sheet.xsd");
        }

        public static XmlSchemaSet LoadPresentationMLSchemas()
        {
            return CreateSchemaSet(
                "..//..//..//Schemas//pml-presentation.xsd",
                "..//..//..//Schemas//pml-slide.xsd");
        }

        private static XmlSchemaSet CreateSchemaSet(params string[] schemaFiles)
        {
            XmlSchemaSet schemas = new XmlSchemaSet();
            foreach (string schemaFile in schemaFiles)
            {
                AddSchemaFile(schemas, schemaFile);
            }
            schemas.Compile();
            return schemas;
        }

        private static void AddSchemaFile(XmlSchemaSet schemas, string path)
        {
            using (XmlReader reader = XmlReader.Create(path))
            {
                schemas.Add(XmlSchema.Read(reader, DisplaySchemaError));
            }
        }

        private static void DisplaySchemaError(object sender, ValidationEventArgs e)
        {
            Console.Error.WriteLine("Schema load error: {0}", e.Message);
        }
       }
      
   调用：
        Console.WriteLine("Validating WordProcessingML");
            ValidateOpenXMLFile(Properties.Resources.WordProcessingMLReport,
                SchemaLoader.LoadWordProcessingMLSchemas());

            Console.WriteLine("Validating SpreadsheetML");
            ValidateOpenXMLFile(Properties.Resources.SpreadsheetMLReport,
                SchemaLoader.LoadSpreadsheetMLSchemas());

            Console.WriteLine("Validating PresentationML");
            ValidateOpenXMLFile(Properties.Resources.PresentationMLReport,
                SchemaLoader.LoadPresentationMLSchemas());
