问题是，当您遵循XML规则时，必须具有单个根元素.但是，当您真的想丢失它时，最直接的方法是替换</NewDataSet>"和< NewDataSet>"和 "".***使用IndexOf和LastIndexOf之类的方法将其删除.

祝你好运！

The problem is that when you follow XML rules it is mandatory to have a single root element. But when you would really like to lose it, the most straight way would be to replace "</NewDataSet>" and "<NewDataSet>" with "". It would be better to use methods like IndexOf and LastIndexOf to remove it.
