3. PowerShell そのものの内容は薄いです。たぶん。予定は未定 PowerShell をC# から実行したい！ • C# というか .NET Framework からですが、コードはC# のみです • 通常の外部プロセス実行だと落とし穴が • コマンドパイプラインも使いたい • リモートコンピューターにも実行したい 最後におまけが！？ 資料と出てくるソースコードは今日中に公開します

13. using (var rs = RunspaceFactory.CreateRunspace()) { rs.Open(); using (var ps = PowerShell.Create()) { ps.Runspace = rs; ps.AddCommand("Get-Service"); ps.Invoke() .Select(result => string.Format("{0} {1}", result.Properties["Status"].Value, result.Properties["Name"].Value)) .ToList() .ForEach(Console.WriteLine); } }
14. using (var rs = RunspaceFactory.CreateRunspace()) { rs.Open(); using (var ps = PowerShell.Create()) { ps.Runspace = rs; ps.AddCommand("Get-Service"); ps.Invoke() .Select(result => string.Format("{0} {1}", result.Properties["Status"].Value, result.Properties["Name"].Value)) .ToList() .ForEach(Console.WriteLine); } }
15. //これでもプロパティ取得できます ps.Invoke() .Select(result => result.BaseObject) .Cast<dynamic>() .Select(result => string.Format("{0} {1}", result.Status, result.ServiceName)) .ToList() .ForEach(Console.WriteLine);
18. DEMO
19. using (var ps = PowerShell.Create()) { ps.Runspace = rs; ps.AddCommand("Get-Process"); ps.AddArgument("chrome"); ps.AddCommand("Sort-Object"); ps.AddParameter("Descending"); ps.AddArgument("CPU"); var results = ps.Invoke(); results.Select(result => string.Format("{0} {1} {2}", result.Properties["Id"].Value, result.Properties["ProcessName"].Value, result.Members["CPU"].Value)) .ToList() .ForEach(Console.WriteLine); }
