用C# 調用PowerShell 3.0

       最近，隨著System Center Virtual Machine Management 2012 SP1 的發布，越來越多的人，加入到私人雲端的開發中來，特別是，開發測試雲端，但國內的技術文檔及資料相當匱乏。前幾天，一個外地的同事在問 “怎麼用C# 調用PowerShell並且取得傳回值”的問題。

解決方案如下：

1. 調用系統的PowerShell，可以用： 

 /// <summary>        /// invoke system powershell        /// </summary>        /// <param name="cmd"></param>        public static void InvokeSystemPS(string cmd)        {            List<string> ps = new List<string>();            ps.Add("Set-ExecutionPolicy RemoteSigned");            ps.Add("Set-ExecutionPolicy -ExecutionPolicy Unrestricted");            ps.Add("& " + cmd);            Runspace runspace = RunspaceFactory.CreateRunspace();            runspace.Open();            Pipeline pipeline = runspace.CreatePipeline();            foreach (var scr in ps)            {                pipeline.Commands.AddScript(scr);            }            pipeline.Invoke();//Execute the ps script            runspace.Close();        }

　　2.調用VMM產品，這裡以“Get-VM -Name vm001” 為例：

 /// <summary>        /// Invoke VMM Poershell        /// </summary>        public static void InvokeVMMPS()        {            RunspaceConfiguration rconfig = RunspaceConfiguration.Create();            PSSnapInException Pwarn = new PSSnapInException();                       Runspace runspace = RunspaceFactory.CreateRunspace();             string test = "Import-Module VirtualMachineManager\r\n";            runspace = RunspaceFactory.CreateRunspace(rconfig); runspace.Open();            Pipeline pipeline = runspace.CreatePipeline();             pipeline.Commands.AddScript(test);             try {                 var results = pipeline.Invoke();                using (Pipeline pipe = runspace.CreatePipeline())                {                    //Get-VM -Name vm001                    Command cmd = new Command("Get-VM");                    cmd.Parameters.Add("Name", "vm001");                    pipe.Commands.Add(cmd);                    var result = pipe.Invoke();                }            }            catch (Exception ex)             {                throw ex;            }        }

Firstly,  you need to add reference "System.Management.Automation".  Then, add two name space:

using System.Management.Automation.Runspaces;

using System.Management.Automation;
