Question

用C＃写的。第二个控制台程序我已经完成了。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机器。即使在尝试连接到远程计算机时，我也会收到相同的消息。

我删除了计算机名称，域名和用户名，但在输入信息时保留了文本。

错误在第50行，foreach（allProcesses中的CimInstance进程）

}

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。查阅目标上运行的WS-Management服务的日志和文档，最常见的是IIS或WinRM。如果目标是WinRM服务，请在目标上运行以下命令以分析和配置WinRM服务：“winrm quickconfig”。'

我已确认该服务正在本地和远程计算机上运行。我很茫然。

因此，在稍微打了一下后，我决定重新开始使用Microsoft的WMI Code Creator（URL：https://www.microsoft.com/en-us/download/details.aspx?id=8572）。这基本上构建了我使用不同于我登录的帐户远程连接所需的一切。

感谢那些花时间看这个的人。

"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
