Powergui中有個工具，可以將PowerShell指令碼轉換成獨立的可執行程式EXE。所以，我想寫一個PowerShell函式，能夠將一個Ps1指令碼檔案轉換成同名的可執行檔案。

知識點分析

• 關鍵應當使用到.Net動態編譯類Microsoft.CSharp.CSharpCodeProvider。在記憶體中編譯，輸出為可執行程式EXE。
• 編譯不通過時，輸出編譯錯誤資訊，包含行號和列號；編譯通過時，輸出應用程式路徑。
• 將要編譯的指令碼作為Resource檔案嵌入到目標應用程式中。
• 為了確保最大的相容性，不適用c#執行PowerShell指令碼，直接使用Process開啟PowerShell.exe ,將指令碼檔案存到臨時目錄傳遞過去執行。
• 將Process執行過程中產生的標準輸出，非同步重定向應用程式。

測試

新建PowerShell指令碼檔案，命名為second.ps1，輸入內容：

1..5 | foreach {
Get-Random
sleep -Milliseconds 500
}
$date=get-date
"Hello,now is $date"
