Message in Chinese (Simplified) (中文(简体))
无法解析实体引用“<var>X</var>”，因为已忽略 DTD。若要启用 DTD 处理，请将 XmlReaderSettings 上的 DtdProcessing 属性设置为 Parse，并将设置传递到 XmlReader.Create 方法中。
Unlocalized message
Cannot resolve entity reference '<var>X</var>' because the DTD has been ignored. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method.
