比如
http://www.cnblogs.com/mail-ricklee/archive/2007/09/25/905724.html
这个控件中的NickLee.Web.UI.dll
反编译正常
反混淆还不要几个方法就出错了，提示是没有将对象设置到实例
又或者
http://www.fcsoft.com.cn/xzzx.htm
下载e表V3.0 for .NET 试用版 (12M 2007-08-30更新)
dll中的ebiao.dll以及ebexcel.dll
打开后反编译先不能显示正常的结果
也是提示未将对象设置到实例
反混淆可以，但实际上是有错的
ebiao.dll反混淆最后提示
共有347个方法时出现异常，生成的PE文件可能不正确
反流程混淆处理完毕，准备生成PE文件
ebexcel.dll也一样
共有88个方法时出现异常，生成的PE文件可能不正确
反流程混淆处理完毕，准备生成PE文件
DONE!
另外生成后的dll都是exe属性
且不是.net dll了
// Assembly test
Location: D:\System\桌面\test.dll
Name: test, Module 'D:\System\桌面\test.dll' does not contain a CLI header.
有什么方面的技巧？
另外还有一些dll、exe就不举例了，也不清楚具体问题出现在哪
