為什么我使用.net的XMLWriter創建的每個XML文件都無法通過W3C驗證？

Question

W3C驗證器告訴我

Line 256, Column 12: non SGML character number 0

這兩個錯誤都發生在文件的末尾。

這是我的縮寫代碼：

            dim writer as XmlWriter
            dim xmlSettings as new XmlWriterSettings
            xmlSettings.Encoding = Encoding.UTF8
            xmlSettings.CheckCharacters = true
            xmlSettings.ConformanceLevel = ConformanceLevel.Document
            xmlSettings.Indent = true

            writer = XmlWriter.Create("D:\somedata.xml", xmlSettings)

            writer.WriteStartDocument()
            writer.WriteStartElement("listings")

            while invReader.Read( )

                writer.WriteStartElement("listing")

                'a bunch of .writeElementString calls here

                writer.WriteEndElement()
            end while       
            writer.WriteEndElement()
            writer.WriteEndDocument()
            writer.Close()

您似乎正在嘗試寫出驗證者認為非法的字符
