从另一个刚刚编译的程序集编译程序集 [英] compiling assembly from the other just compiled assembly
问题描述
我需要在内存中编译程序集,可以编译另一个.有一个带有一个按钮的表单.这是表格的代码
I need to compile assembly in memory, that can compile another one. There is a form with one button. Here is a code of the form

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.此示例在 C# 中进行了一些更改(http://stackoverflow.com/questions/5729403/compilling-assembly-from-the-other-just-compilled-assembly) 也许有人懂 vb 和 c# 并帮助我理解两个例子之间的区别?
When I click Button1 in first form -> appears second form. but when I click Button 1 in the second form I have an FileNotFound Exception. What am I doing wrong? There is an interesting moment. This example with some changes work in C#(http://stackoverflow.com/questions/5729403/compilling-assembly-from-the-other-just-compilled-assembly) Maybe There are people who knows vb and c# and helps me to understand differences between two examples?
推荐答案
您是否尝试将 assemblyDomain.DoCallBack(AddressOf assamblykub)
替换为 assamblykub
函数的简单调用?
Did you tried to replace assemblyDomain.DoCallBack(AddressOf assamblykub)
with simple call of assamblykub
function ?
