如果您能帮助我摆脱下面的这些警告，那就太好了。我一直没能找到一个好的文件。由于警告仅集中在该private void ValidateConfiguration( XmlNode section )部分中，因此如果您以前遇到过此问题，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'System.Configuration.ConfigurationException.ConfigurationException(string)' is obsolete: 'This class is obsolete, to create a new exception create a System.Configuration!System.Configuration.ConfigurationErrorsException'   

'System.Xml.XmlValidatingReader' is obsolete: 'Use XmlReader created by XmlReader.Create() method using appropriate XmlReaderSettings instead.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 );
    }
}

基本上，它告诉您使用已弃用XmlReaderSettings的 the 而不是。XmlValidatingReader

我个人不打算进行转换，我认为您实际上这样做会对您的编码开发有好处，所以这里有一些资源：

查看XmlReader.Create()方法的重载，特别是this。

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

试一试，看看会发生什么，如果仍然有问题，请再问一个问题 :)

  1. 替换 throw new ConfigurationException(....) 为

    throw new ConfigurationErrorsException(....)

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

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