Question

我正在尝试编写一个C＃核心程序，以在远程linux系统上运行powershell脚本。在.net core上运行是此项目的要求。我正试图宽松地遵循在CodeProject上找到的指南。

这是我的代码：

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

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {

            SSHConnectionInfo connectionInfo = new SSHConnectionInfo(userName: "user", computerName: "server", keyFilePath: "id_rsa");


            using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
            {
                runspace.Open(); // The program errors out here
                runspace.Close();

            }

        }
    }
}

我的“ id_rsa”文件位于与程序相同的文件夹中。我已验证Windows的openssh，powershell核心6.0.2和.net核心2 SDK已安装并正常工作。我正在使用Microsoft Powershell Core repository中的以下nuget软件包：Microsoft.PowerShell.SDK（6.0.2）和Sytem.Managment.Automation（6.0.2）

这是我收到的错误：

Unhandled Exception: System.Management.Automation.Remoting.PSRemotingDataStructureException: An error has occurred which PowerShell cannot handle. A remote session might have ended. ---> System.ArgumentException: The path is not of a legal form.
Parameter name: path
   at System.IO.Path.GetDirectoryName(String path)

   at System.Management.Automation.RemoteRunspace.Open()
   at ConsoleApp1.Program.Main(String[] args) in C:\ConsoleApp1\ConsoleApp1\Program.cs:line 18
Press any key to continue . . .

这时我不确定我缺少什么。

我最终在github上打开了一个issue来解决此错误。当前要解决此问题，您将需要在程序中添加以下代码，直到在以后的Powershell内核版本（> 6.0.4或> 6.1.0-rc.1）中解决此issue为止。 Here is the specific post regarding the issue.

if (System.Management.Automation.Runspaces.Runspace.DefaultRunspace == null)
{
    var defaultRunspace = RunspaceFactory.CreateRunspace();
    defaultRunspace.Open();
    System.Management.Automation.Runspaces.Runspace.DefaultRunspace = defaultRunspace;
}

c＃Core System.Management.Automation远程连接错误
