Sampel Kode RunSpace03 (C#)

Berikut adalah kode sumber C# untuk aplikasi konsol yang dijelaskan dalam "Membuat Aplikasi Konsol yang Menjalankan Skrip Yang Ditentukan". Sampel ini menggunakan kelas System.Management.Automation.RunspaceInvoke untuk menjalankan skrip yang mengambil informasi proses dengan menggunakan daftar nama proses yang diteruskan ke dalam skrip. Ini menunjukkan cara meneruskan objek input ke skrip dan cara mengambil objek kesalahan serta objek output.

Nota

Anda dapat mengunduh file sumber C# (runspace03.cs) untuk sampel ini menggunakan Microsoft Windows Software Development Kit untuk Windows Vista dan Komponen Runtime Microsoft .NET Framework 3.0.
