当我点击第一种形式的Button1时 - ＆gt;出现第二种形式。但是当我在第二种形式中单击按钮1时，我有一个FileNotFound异常。我究竟做错了什么？有一个有趣的时刻。这个带有一些变化的例子在C＃中工作（http://stackoverflow.com/questions/5729403/compilling-assembly-from-the-other-just-compilled-assembly）也许有些人知道vb和c＃，并帮助我理解两个例子之间的差异？

您是否尝试通过简单调用assemblyDomain.DoCallBack(AddressOf assamblykub)函数替换assamblykub？

从另一个刚编译的程序集编译程序集
