连接到远程 PC 以监控正在运行的服务时出错

Question

这是用 C# 编写的。我完成的第二个控制台程序。它编译并运行。但是当它连接到客户端时。它说客户端不存在。我通过 PC 名称在代码中连接到我的本地计算机。即使尝试连接到远程计算机，我也会收到相同的消息。

我删除了计算机名称、域和用户名，但在输入信息时留下了文字。

错误出现在第 50 行，foreach（所有进程中的 CimInstance 进程）

            }
        }Console.ReadLine();
    }   
}

}

以下是我得到的错误

Microsoft.Management.Infrastructure.CimException: '客户端无法连接到请求中指定的目标。验证目标上的服务是否正在运行并且正在接受请求。请查阅在目标（最常见的是 IIS 或 WinRM）上运行的 WS-Management 服务的日志和文档。如果目标是 WinRM 服务，在目标上运行以下命令来分析和配置 WinRM 服务：“winrm quickconfig”。'

我已确认该服务正在我的本地和远程计算机上运行。我很茫然。

因此，在解决了这个问题之后，我决定重新开始使用 Microsoft 的 WMI Code Creator（网址：https://www.microsoft.com/en-us/download/details.aspx?id=8572）。这基本上构建了我使用与我登录时不同的帐户进行远程连接所需的一切。

感谢那些花时间仔细研究的人。

"The error means you haven’t got the winrm service running on the local/remote machine. On modern Windows remoting, and therefore winrm, are enable by default for servers but disable for client OS e.g. Windows 10. Easiest way to get this to work is run 'Enable-PSremoting' from and elevated PowerShell prompt."

We should not be using WMI anymore because it is deprecated
