请帮我将 .NET 1.1 Xml 验证代码转换为 .NET 2.0

Question

如果您能帮助我消除下面的这些警告，那就太好了。 我一直找不到好的文档。由于警告仅集中在 private void ValidateConfiguration( XmlNode section ) 部分，因此如果您以前遇到过这种情况，希望这不是很难回答。

谢谢！

'System.Configuration.ConfigurationException.ConfigurationException(string)' is obsolete: 'This class is obsolete, to create a new exception create a System.Configuration!System.Configuration.ConfigurationErrorsException'   

'System.Xml.XmlValidatingReader' is obsolete: 'Use XmlReader created by XmlReader.Create() method using appropriate XmlReaderSettings instead. http://go.microsoft.com/fwlink/?linkid=14202'

private void ValidateConfiguration( XmlNode section )
{                
    // throw if there is no configuration node.
    if( null == section )
    {
        throw new ConfigurationException("The configuration section passed within the ... class was null ... there must be a configuration file defined.", section );
    }
    //Validate the document using a schema
    XmlValidatingReader vreader = new XmlValidatingReader( new XmlTextReader( new StringReader( section.OuterXml ) ) );
    //  open stream on Resources; the XSD is set as an "embedded resource" so Resource can open a stream on it
    using (Stream xsdFile = XYZ.GetStream("ABC.xsd"))
    using (StreamReader sr = new StreamReader(xsdFile))
    {
        vreader.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
        vreader.Schemas.Add(XmlSchema.Read(new XmlTextReader(sr), null));
        vreader.ValidationType = ValidationType.Schema;
        // Validate the document
        while (vreader.Read()) { }

        if (!_isValidDocument)
        {
            _schemaErrors = _sb.ToString();
            throw new ConfigurationException("XML Document not valid");
        }
    }
}

// Does not cause warnings.
private void ValidationCallBack( object sender, ValidationEventArgs args )
{
    //  check what KIND of problem the schema validation reader has;
    //  on FX 1.0, it gives a warning for "<xs:any...skip" sections.  Don't worry about those, only set validation false
    //  for real errors
    if( args.Severity == XmlSeverityType.Error )
    {
        _isValidDocument = false;
        _sb.Append( args.Message + Environment.NewLine );
    }
}

Answer 1

1. 替换
   <代码>
   抛出新的配置异常（....）

   与

   <代码>
   抛出新的 ConfigurationErrorsException(....)
   替换

2. 替换XmlValidatingReader vreader = new XmlValidatingReader(...)
   用

var vreader = XmlReader.Create(new StringReader(section.OuterXml), 
                               new XmlReaderSettings
                               {
                                  ValidationType = ValidationType.Schema
                               });

Answer 2

基本上，它告诉您使用 XmlReaderSettings 而不是 XmlValidatingReader，后者已被弃用。

就我个人而言，我不会进行转换，我认为您实际上这样做将有利于您的编码开发，因此这里有一些资源：

查看 XmlReader.Create() 的重载方法，特别是这个。

然后查看与 XmlReaderSettings 类关联的不同属性：http://msdn.microsoft.com/en-us/library/system.xml.xmlreadersettings_members.aspx

尝试一下，看看会发生什么，如果仍然遇到问题，请询问另一个问题:)
