如何构建WMI查询

我想找到名称以param1开头的结果，并以param2结尾但我的代码不起作用

string wmiQuery = string.Format("SELECT CommandLine FROM Win32_Process WHERE Name LIKE '{0}%' AND Name LIKE '%{1}'", param1, param2); ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmiQuery); ManagementObjectCollection retObjectCollection = searcher.Get(); 

怎么了？

比较

 string wmiQuery = string.Format("SELECT CommandLine FROM Win32_Process WHERE Name LIKE '{0}%'", param1); 

效果很好

Answer 1

试试这个：

 string wmiQuery = string.Format("SELECT CommandLine FROM Win32_Process WHERE Name LIKE '{0}%{1}'", param1, param2); 

添加一些测试信息：

 string wmiQuery = string.Format ( "SELECT Name, ProcessID FROM Win32_Process WHERE Name LIKE '{0}%{1}'", "wpf", ".exe" ); Console.WriteLine ( "Query: {0}", wmiQuery ); ManagementObjectSearcher searcher = new ManagementObjectSearcher ( wmiQuery ); ManagementObjectCollection retObjectCollection = searcher.Get ( ); foreach (ManagementObject retObject in retObjectCollection) { Console.WriteLine ( "[{0}]\tName: {1}", retObject[ "ProcessID" ], retObject["Name"] ); } 

输出：

查询：SELECT Name，ProcessID FROM Win32_Process WHERE Name LIKE’wpf％.exe’
[896]名称：WPFFontCache_v0400.exe
