Question

以下代码抛出XML反序列化错误（20,2），我不知道为什么。 XmlSerialiser是否有一些特殊的特殊功能可以知道DataSets的反序列化？

Dim strStringReader As StringReader = New StringReader(strValue)
Dim oXS As XmlSerializer = New XmlSerializer(strObjectType)
Deserialize = oXS.Deserialize(strStringReader)

这是xml（在字符串strValue中可用）：

<?xml version='1.0' encoding='utf-16'?>

对于DataSet和DataTables，有write和read Xml的特殊方法。 DataSet和DataTables可以通过多种方式进行序列化，因此存在一些过载。从您在问题中显示的XML中，我怀疑调用者向您的Web服务发送DiffGram DataTable，这是一种特殊格式，包含对DataSet或DataTable中的数据所做的更改。 /> 您可以使用ReadXml重载之一来阅读DiffGram。
