See below the results of Get-WmiObject win32_processor -ComputerName <computername> 标题  &NBSP; &NBSP; &NBSP; &NBSP; ：x86 Family 15 Model 6 Stepping 5 DeviceID  &NBSP; &NBSP; &NBSP;  ：CPU0 制造商  &NBSP;  ：GenuineIntel MaxClockSpeed  &NBSP; ：2800 名称  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;  ：Intel（R）Pentium（R）D CPU 2.80GHz SocketDesignation： LGA775 标题  &NBSP; &NBSP; &NBSP; &NBSP; ：x86 Family 15 Model 6 Stepping 5 DeviceID  &NBSP; &NBSP; &NBSP;  ：CPU1 制造商  &NBSP;  ：GenuineIntel MaxClockSpeed  &NBSP; ：2800 名称  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;  ：Intel（R）Pentium（R）D CPU 2.80GHz SocketDesignation： LGA775Caption           : x86 Family 15 Model 6 Stepping 5DeviceID          : CPU0Manufacturer      : GenuineIntelMaxClockSpeed     : 2800Name              : Intel(R) Pentium(R) D CPU 2.80GHzSocketDesignation : LGA775Caption           : x86 Family 15 Model 6 Stepping 5DeviceID          : CPU1Manufacturer      : GenuineIntelMaxClockSpeed     : 2800Name              : Intel(R) Pentium(R) D CPU 2.80GHzSocketDesignation : LGA775我试图通过流水线"Where-Object"来减少结果的数量。像这样（我不包括圆形声明，认为在尝试对它运行数学之前获得单个数字结果会更好。）I attempted to lessen the number of results with a pipelined "Where-Object" like this (I am not including the round statement, figuring that it'd be better to get a single numeric result before attempting to run the math against it).(Get-WmiObject win32_processor -ComputerName <computername>).MaxClockSpeed | Where-Object {$_.DeviceID -like 'CPU0'}不幸的是，当我运行它时，而不是从标识为DeviceID"CPU0"的处理器获取MaxClockSpeed结果我什么都没得到。Unfortunately, when I run this, instead of getting the MaxClockSpeed result from the processor identified as DeviceID "CPU0", I get nothing at all.我认为这可能是因为我在Where-Object语句中使用了错误的限定符（我试过-eq而不是-like），但是还没有能够超越这一点。I thought this might be because I'm using the wrong qualifier in the Where-Object statement (I tried -eq instead of -like), but haven't been able to get past this point.建议，帮助和指针总是*赞赏。Suggestions, help and pointers are *always* appreciated.谢谢， Ben推荐答案 我想我找到了解决办法。  我管道它并使用select-object指定使用第一个结果。I think I found my solution.  I pipe it and use select-object specifying to use the first result.感谢您的观点！  如果您想出一个更优雅的解决方案，请随时回复。Thanks for the views!  If you come up with a more elegant solution feel free to reply.
