推荐答案

我们不知道什么是PdfWRiter或htmlparser.它们不是.NET框架的一部分.我们不知道错误是什么，您没有告诉我们.我们无法读懂思想或做魔术.您需要告诉我们更多信息，或者与您使用的控件的提供者进行交谈.

We don''t know what PdfWRiter or htmlparser are. They are not part of the .NET framework. We don''t know what the error is, you did not tell us. We cannot read minds or do magic. You need to tell us more, or perhaps talk to the provider of the controls you''re using.
