将PowerShell脚本编译成EXE

Powergui中有个工具，可以将PowerShell脚本转换成独立的可执行程序EXE。所以，我想写一个PowerShell函数，能够将一个Ps1脚本文件转换成同名的可执行文件。

知识点分析

• 关键应当使用到.Net动态编译类Microsoft.CSharp.CSharpCodeProvider。在内存中编译，输出为可执行程序EXE。

• 编译不通过时，输出编译错误信息，包含行号和列号；编译通过时，输出应用程序路径。

• 将要编译的脚本作为Resource文件嵌入到目标应用程序中。

• 为了确保最大的兼容性，不适用c#执行PowerShell脚本，直接使用Process打开PowerShell.exe ,将脚本文件存到临时目录传递过去运行。

• 将Process运行过程中产生的标准输出，异步重定向应用程序。
