例如: function CreateXMLAndLoadFromStream(S: TStream): TNativeXml; begin Result := TNativeXml.Create...Result.LoadFromStream(S); end; 如果你知道你的流具有一定的编码,你可以强制NativeXml使用这种编码,例如: function CreateXMLAndLoadFromUTF8Stream(S: TStream
TStream,TFileStream,TMemoryStream和TResourceStream类都可以读写数据流,TStream是所有数据流类的基类,当处理磁盘上的文件时就会用到TFileStream
