asp.net – 从命令行包含项目中的文件

首先,简单的部分.以下是从命令提示符运行脚本的方法.

powershell -File C:AddExistingItem.ps1 -solutionPath "C:Test.sln" -projectName "TestAddItem" -item "C:Test.txt"

现在可怕的部分,AddExistingItem.ps1：

param([String]$solutionPath,[String]$projectName,[String]$item)

95％的代码只允许您从命令提示符运行.如果您直接在PowerShell中编写和运行代码,则可以将其保留并直接转到$IDE = New-Object -ComObject VisualStudio.DTE.

Here是一篇博客文章,解释了为什么需要这些可怕的东西.
而here是另一个同样的东西,但在C#中.

另一件值得注意的事情.我尝试使用EnvDTE程序集,就像在.net中一样,但我一直收到COM注册错误.一旦我开始使用COM对象直接一切正常.我不太了解COM真的冒险猜测为什么会这样.

如果在尝试从命令提示符运行脚本时收到此错误：

然后你需要先运行它(你应该只需要运行一次.)

powershell -command“Set-ExecutionPolicy -ExecutionPolicy RemoteSigned”

Here是对该命令正在做什么的一个很好的,深入的解释.
