.NET：在验证/读取XML模式时阻止Web访问？
|
在尝试使用XML模式验证XML文档时，我试图阻止.NET Framework访问Web，因为我不希望它一直依赖于对Web的访问。为此，我在验证时有意创建了我正在使用的所有XSD \ s的本地硬盘副本，但在加载某些这些架构时仍然失败。
例如，这段代码失败（但仅当从网络上拔下我的机器时）：
using (Stream schemaStream = File.OpenRead(schemaFileName))
{
XmlSchema schema = XmlSchema.Read(schemaStream, ValidationCallBack);
xmlSchemaSet.Add(schema);
}
schemaFileName
System.Net.WebException: The remote name could not be resolved: \'www.w3.org\'

实现，可以重新路由到我的XSD文件的本地副本，但是现在我在加载XML模式时也需要将其用于DTD：using (Stream schemaStream = File.OpenRead(schemaFileName)) { XmlReaderSettings xmlReaderSettings = new XmlReaderSettings(); xmlReaderSettings.XmlResolver = myXmlNamespaceResolver; xmlReaderSettings.ProhibitDtd = false; using (XmlReader reader = XmlReader.Create(schemaStream, xmlReaderSettings)) { XmlSchema schema = XmlSchema.Read(reader, ValidationCallBack); xmlSchemaSet.Add(schema); } }
