C# 终止进程需要WQL“;选择*.quot;?
我正在编写代码,以便在指定的时间后终止特定进程。我正在使用以下代码(简化后): 问题在于,使用C# 终止进程需要WQL“;选择*.quot;?,c#,.net,wmi,wql,C#,.net,Wmi,Wql,我正在编写代码,以便在指定的时间后终止特定进程。我正在使用以下代码(简化后): 问题在于,使用SELECT Name的WQL语句,CreationDate在尝试执行以下操作时引发异常: "Operation is not valid due to the current state of the object." …但是,使用SELECT*可以工作并终止进程。为什么--结果集中是否需要特定的WMI列 谢谢 当执行WMI方法时,将执行WMI内部searh,以便通过该方法识别实例 在这种情况下,对
SELECT Name的WQL语句,CreationDate
在尝试执行以下操作时引发异常:
"Operation is not valid due to the current state of the object."
…但是,使用SELECT*
可以工作并终止进程。为什么--结果集中是否需要特定的WMI列
谢谢 当执行WMI方法时,将执行WMI内部searh,以便通过该方法识别实例 在这种情况下,对于WMI类,WMI对象路径类似于Win32_Process.Handle=“8112”,因此正如您所看到的,
Handle
属性是WMI对象路径的一部分,必须包含在WQL语句中

你是说“选择句柄,名称,创建日期”是需要的吗?我刚刚测试过——是的,只需将句柄添加到WQL就可以实现终止。谢谢你是说“选择句柄,名称,创建日期”是需要的吗?我刚刚测试过——是的,只需将句柄添加到WQL就可以实现终止。谢谢
