c# - 从 C# 远程连接到 powershell

Question

我想使用 ASP.NET 将 powershell 从 Windows 7 远程连接到 Windows Server 2008 R2(安装在 VMware 中)。

这是我的代码:

    string shell = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
    var target = new Uri("http://win-qkheb9s51i8/wsman");

    Pipeline p = runSpace.CreatePipeline();
    SecureString passing = new SecureString();
    string password = "A123456a";

    foreach (char c in password)
    {
        passing.AppendChar(c);
    }
    passing.MakeReadOnly();

    var cred = new PSCredential(@"win-qkheb9s51i8\Administrator", passing);

    var connectionInfo = new WSManConnectionInfo(target, shell, cred);
    connectionInfo.OperationTimeout = 4 * 60 * 1000; // 4 minutes.
    connectionInfo.OpenTimeout = 1 * 60 * 1000;
   runSpace = RunspaceFactory.CreateRunspace(connectionInfo);
   runSpace.Open();

但是在runSpace.open()中有时会报这个错

Connecting to remote server failed with the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic.

有时这个错误:

ERROR: The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests.

我阅读了 about_Remote_Troubleshooting 但我不明白为什么会出现这些错误。谁能帮帮我？

好吧，你说两台机器都在同一个域中，但我看到你正在尝试使用本地管理员帐户。这可能是一个问题，但不一定。为了复制这个，我在 VM 上设置了 Win2k8R2 并按照以下步骤操作:

第 1 步和第 2 步适用于 Server 2008 R2 核心安装。如果您有完整安装，请跳至#3。

1. 运行以下命令以安装 .NET2 和 PowerShell(在 cmd.exe 中)
   • DISM/Online/Enable-Feature/Featurename:NetFx2-ServerCore
   • DISM/Online/Enable-Feature/FeatureName:MicrosoftWindowsPowerShell
2. 安装一些有用的 PS CmdLets(在 cmd.exe 中)
   • DISM/online/enable-feature/featurename=ServerManager-PSH-Cmdlets
   • DISM/online/enable-feature/featurename=BestPractices-PSH-Cmdlets
3. 启用远程 Shell(在 powershell.exe 中)
   • 设置执行策略 RemoteSigend
   • Configure-SMRemoting.ps1 -force -enable

然后我拿了你的示例代码，我并没有对它做任何实质性的改动

        Console.Write("Target: ");
        var target = Console.ReadLine();
        Console.Write("User: ");
        var user = Console.ReadLine();
        user = string.Format("{0}\\{1}", target, user);
        string shell = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
        var targetWsMan = new Uri(string.Format("http://{0}:5985/wsman", target));

        using (var passing = new SecureString())
        {
            Console.Write("Password: ");
            var cki = default(ConsoleKeyInfo);
            do
            {
                cki = Console.ReadKey(true);
                if (cki.Key == ConsoleKey.Enter)
                    Console.Write(cki.KeyChar);
                else
                    passing.AppendChar(cki.KeyChar);
            }
            while (cki.Key != ConsoleKey.Enter);
            passing.MakeReadOnly();

            var cred = new PSCredential(user, passing);

            var connectionInfo = new WSManConnectionInfo(targetWsMan, shell, cred);
            connectionInfo.OperationTimeout = 4 * 60 * 1000; // 4 minutes.
            connectionInfo.OpenTimeout = 1 * 60 * 1000;
            using (var runSpace = RunspaceFactory.CreateRunspace(connectionInfo))
            {
                var p = runSpace.CreatePipeline();
                runSpace.Open();
                Console.WriteLine("Connected to {0}", targetWsMan);
                Console.WriteLine("As {0}", user);
                Console.Write("Command to run: ");
                var cmd = Console.ReadLine();
                p.Commands.Add(cmd);
                var returnValue = p.Invoke();
                foreach (var v in returnValue)
                    Console.WriteLine(v.ToString());
            }
        }

        Console.WriteLine("End...");
        Console.ReadLine();

我确实添加了对 C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0\System.Management.Automation.dll 的 dll 引用，以防万一它不是您使用的.

然后就成功了。所以我的感觉是，这不是您的代码，而是您的凭据或目标机器上的远程设置。
