Question

我试图在.NET 4.5上使用WMI / C＃终止远程计算机上的进程。在下面的代码中，当在ManagementObjectSearcher实例上调用Get方法时，不会返回任何内容，因此未到达foreach中的行。 ManagementScope已连接，查询变量包含终止进程的名称。感谢任何帮助。

try
        {
            ConnectionOptions connOptions = new ConnectionOptions();
            connOptions.Impersonation = ImpersonationLevel.Impersonate;
            connOptions.EnablePrivileges = true;
            ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", NetworkName), connOptions);
            manScope.Connect();
            var query = new SelectQuery("select * from Win32_process where name = '" + ProcessName + "'");

            using (var searcher = new ManagementObjectSearcher(manScope, query))
            {
                foreach (ManagementObject process in searcher.Get())
                {
                    process.InvokeMethod("Terminate", null);
                }
            }
        }
        catch (ManagementException err)
        {
            //Do something with error message here
        }

正如我在上面的评论中所述，为了完整性，这里的代码包含我的更改，如下所示。

        try
        {
            ConnectionOptions connOptions = new ConnectionOptions();
            connOptions.Impersonation = ImpersonationLevel.Impersonate;
            connOptions.EnablePrivileges = true;
            ManagementScope manScope = new ManagementScope(String.Format(@"\\{0}\ROOT\CIMV2", NetworkName), connOptions);
            manScope.Connect();
            ProcessName = ProcessName + ".exe";

            using (var searcher = new ManagementObjectSearcher(manScope, new SelectQuery("select * from Win32_Process where Name = '" + ProcessName + "'")))
            {
                foreach (ManagementObject process in searcher.Get())
                {
                    process.InvokeMethod("Terminate", null);
                }
            }
        }
        catch (ManagementException err)
        {
            //Do something with error message here
        }

Answer 2

使用Count属性检查是否包含任何记录。也就是说，if(searcher.Get().count == 0)返回true，表示没有记录。

Answer 3

就我而言，我无法使用WMI查询远程接收CPU利用率值：

SELECT PercentProcessorTime FROM Win32_PerfFormattedData_PerfOS_Processor WHERE Name='_Total'

我将项目构建平台的目标从任何CPU 更改为 x64 ，以匹配我的系统位数，从而解决了问题。另一种方法是，取消选中任何CPU 的首选32位复选框。

ManagementObjectSearcher Get（）方法不返回任何结果
