最近,随着System Center Virtual Machine Management 2012 SP1 的发布,越来越多的人,加入到私有云的开发中来,特别是,开发测试云,但国内的技术文档及资料相当匮乏。前几天,一个外地的同事在问 “怎么用C# 调用PowerShell并且取得返回值”的问题。
解决方案如下:
- 调用系统的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.调用VMM产品,这里以“Get-VM -Name vm001” 为例:
/// <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;
