需要添加对 system.management.dll 的引用

复制代码代码如下:

using system.diagnostics; 
using system.management;static void main(string[] args) 
{ 
foreach (process p in process.getprocesses()) 
{ 
console.write(p.processname); 
console.write("----"); 
console.writeline(getprocessusername(p.id)); 
} 
console.readkey(); 
}private static string getprocessusername(int pid) 
{ 
string text1 = null; 
selectquery query1 = new selectquery("select * from win32_process where processid=" + pid); 
managementobjectsearcher searcher1 = new managementobjectsearcher(query1); 
try 
{ 
foreach (managementobject disk in searcher1.get()) 
{ 
managementbaseobject inpar = null; 
managementbaseobject outpar = null; 
inpar = disk.getmethodparameters("getowner"); 
outpar = disk.invokemethod("getowner", inpar, null); 
text1 = outpar["user"].tostring(); 
break; 
} 
} 
catch 
{ 
text1 = "system"; 
} 
return text1; 
}
