vb.net代码生成器,VB编程器

vb.net 自建类生成类e似xx.item(0).value或者xx.Name("zhangshan").Value

'这是数组的一个方法了，可是可以给数组定义扩展方法来实现这种形式。不过要给Item每个成员能动态生成相应方法，想不出其它简单点的办法，只能一个一个的添加扩展方法。

vb.net源代码如何生成exe格式

vb.net编译出来的exe只有依赖.net

framework才能运行

但有一些第三方工具可以用来把exe用到的assembly和dll打包成一个exe文件，不过这样的结果就是exe体积非常大

比如.netz工具，它的官方地址：

使用很简单，比如你的exe文件是a.exe，直接netz

a.exe就可以把a和它用到的.net代码一起打包成一个exe
