將PowerShell腳本編譯成EXE

Powergui中有個工具，能夠將PowerShell腳本轉換成獨立的可執行程序EXE。因此，我想寫一個PowerShell函數，可以將一個Ps1腳本文件轉換成同名的可執行文件。

知識點分析

• 關鍵應當使用到.Net動態編譯類Microsoft.CSharp.CSharpCodeProvider。在內存中編譯，輸出爲可執行程序EXE。

• 編譯不經過時，輸出編譯錯誤信息，包含行號和列號；編譯經過時，輸出應用程序路徑。

• 將要編譯的腳本做爲Resource文件嵌入到目標應用程序中。

• 爲了確保最大的兼容性，不適用c#執行PowerShell腳本，直接使用Process打開PowerShell.exe ,將腳本文件存到臨時目錄傳遞過去運行。

• 將Process運行過程當中產生的標準輸出，異步重定向應用程序。
