当我在第一种形式中单击 Button1 -> 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。这个示例在 C# 中进行了一些更改（http://stackoverflow.com/questions/5729403/compilling-assembly-from-the-other-just-compilled-assembly）也许有人知道 vb 和 c# 并帮助我了解两个示例之间的差异吗？

您是否尝试assemblyDomain.DoCallBack(AddressOf assamblykub)用简单的assamblykub函数调用替换？
