如何从C#运行PowerShell脚本

Answer 1

在C#中调用powershell脚本，需要引用的namespace如下：

using System.Management.Automation;
using System.Management.Automation.Runspaces;

添加System.Management.Automation.dll的引用，需要使用浏览，如果不知道位置，可以先在本机查找下。

代码如下：

1 //RunPowershell(@".\x.ps1", "");
2 private Collection<PSObject> RunPowershell(string filePath, string parameters)
3 {
4 RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
5 Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
6 runspace.Open();
7 RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
8 Pipeline pipeline = runspace.CreatePipeline();
9 Command scriptCommand = new Command(filePath);
10 Collection<CommandParameter> commandParameters = new Collection<CommandParameter>();
11
12 string[] tempParas = parameters.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
13 for (int i = 0; i < tempParas.Length; i += 2)
14 {
15 CommandParameter commandParm = new CommandParameter(tempParas[i], tempParas[i + 1]);
16 commandParameters.Add(commandParm);
17 scriptCommand.Parameters.Add(commandParm);
18 }
19
20 pipeline.Commands.Add(scriptCommand);
21 Collection<PSObject> psObjects;
22 psObjects = pipeline.Invoke();
23
24 if (pipeline.Error.Count > 0)
25 {
26 throw new Exception("脚本执行失败");
27 }
28
29 runspace.Close();
30
31 return psObjects;
32 }
