WMI 查询中的转义字符问题

Question

processName.Name = @"\dfs\ns1\Application_Data\tiny\Development\tinyLOS\tinyLOS.exe";

string wmiQuery = string.Format("select CommandLine from Win32_Process where PathName='{0}'", processName.Name);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmiQuery);
ManagementObjectCollection retObjectCollection = searcher.Get();

我正在尝试运行使用 WMI 在 C# 中编写上述代码，但在执行时我一直收到无效查询错误。我怀疑转义反斜杠是个问题，但我想我已经用 @ 解决了这个问题。我是否遗漏了一些简单的东西，因为这看起来应该可以正常执行？

（注：反斜杠去掉后执行查询）

您需要传递转义斜杠，它是 ExecutablePath 而不是 PathName

wmiQuery = @"SELECT CommandLine FROM Win32_Process WHERE ExecutablePath =
            'C:\Program Files\Microsoft Security Client\msseces.exe'";

var searcher = new ManagementObjectSearcher("root\CIMV2", wmiQuery);

foreach (ManagementObject queryObj in searcher.Get())
    Console.WriteLine("CommandLine: {0}", queryObj["CommandLine"]);

对于

CommandLine: "C:\Program Files\Microsoft Security Client\msseces.exe" -hide -runkey
