如何从 C# 执行 PowerShell 命令“open-device”？

Question

我正在使用open-device 127.0.0.1 连接远程设备。如何从 C# 调用它？这段代码：

PowerShell powerShell = PowerShell.Create(); 
PSCommand connect = new PSCommand();
connect.AddCommand("open-device");
powerShell.Commands = connect;
PSOutput = powerShell.Invoke()

导致错误：

System.Management.Automation.CommandNotFoundException：术语open-device 未被识别为 cmdlet、函数、脚本文件或可运行程序的名称。检查名称的拼写，如果包含路径，请验证路径是否正确，然后重试。 at

 System.Management.Automation.Runspaces.PipelineBase.Invoke(IEnumerable input) at
 System.Management.Automation.Runspaces.Pipeline.Invoke() at
 System.Management.Automation.PowerShell.Worker.ConstructPipelineAndDoWork(Runspa‌​ce rs, Boolean performSyncInvoke)

但是，我可以使用Invoke 运行get-service 命令。

您需要首先使用 Import-Module cmdlet 等效项 => 加载其模块，这是通过 InitialSessionState 的 ImportPSModule() 方法完成的。

下面是我的 DnsClient 模块示例：

using System;
using System.Collections.ObjectModel;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Text;

namespace PowershellTest1
{
    class Program
    {
        static void Main(string[] args)
        {
            InitialSessionState initial = InitialSessionState.CreateDefault();
            String[] modules = { "DnsClient" };
            initial.ImportPSModule(modules);
            Runspace runspace = RunspaceFactory.CreateRunspace(initial);
            runspace.Open();
            RunspaceInvoke invoker = new RunspaceInvoke(runspace);

            Collection<PSObject> results = invoker.Invoke("Resolve-DnsName 'localhost'");
            runspace.Close();

            // convert the script result into a single string

            StringBuilder stringBuilder = new StringBuilder();
            foreach (PSObject obj in results)
            {
                foreach (PSMemberInfo m in obj.Members)
                {
                    stringBuilder.AppendLine(m.Name + ":");
                    stringBuilder.AppendLine(m.Value.ToString());
                }
            }

            Console.WriteLine(stringBuilder.ToString());
            Console.ReadKey();
        }
    }
}
