解决方案二：
换个思路就好了，分段操作，分段序列化，分段写入，别让内存太累。。。
解决方案三：
可以使用文件流试试try{XmlSerializerxmlFormat=newXmlSerializer(typeof(List<KeyWords>));using(StreamfStream=newFileStream(serializeFileFullName,FileMode.Create,FileAccess.Write,FileShare.None)){xmlFormat.Serialize(fStream,listKeyWords);}}catch(Exceptione){Trace.WriteLine(e.ToString());}
