最近看到一个考试系统,有个功能是用来监视进程的。一旦发现如communicator.exe这样的违禁软件就立即杀死进程并上报给服务器。我稍 微研究了一下,这个功能实现起来其实很简单。就是使用managementobjectsearcher获取进程列表,然后放在一个collection 里,之后就可以按照自己的逻辑去做了。

复制代码 代码如下:

using system;
using system.management;

namespace consoleapplication3
{

    class program
    {
        static void main(string[] args)
        {
            // show process list
            console.writeline("===========process list===========");
            managementobjectcollection objects = new managementobjectsearcher("select * from win32_process").get();
            foreach (managementobject item in objects)
            {
                console.writeline((item["name"].tostring()));
            }

            // create ban list
            console.writeline("===========ban list===========");
            string lst = "communicator.exe,powerpnt.exe,notepad.exe";
            string[] bannedproc = lst.split(‘,‘);
            foreach (string s in bannedproc)
            {
                console.writeline(s);
            }

            // search and destroy
            console.writeline("===========search and destroy===========");
            console.writeline("searching for banned process...");
            int count = 0;
            foreach (string item in bannedproc)
            {
                if (detectprocess(item))
                {
                    count++;
                    console.writeline("process [{0}] detected!", item);
                    console.writeline("[{0}] was killed {1}.", item, killprocess(item) ? "successfully" : "unsucessfully");
                }
            }
            console.writeline("done, {0} banned process found", count);
        }

        protected static bool detectprocess(string pprocessname)
        {
            managementobjectcollection objects = new managementobjectsearcher("select * from win32_process").get();
            foreach (managementobject item in objects)
            {
                string str = item["name"].tostring();
                if (str.trim().toupper() == pprocessname.trim().toupper())
                {
                    return true;
                }
            }
            return false;
        }

        public static bool killprocess(string pprocessname)
        {
            managementobjectcollection objects = new managementobjectsearcher("select * from win32_process").get();
            foreach (managementobject item in objects)
            {
                string str = item["name"].tostring();
                if (str.trim().toupper() == pprocessname.trim().toupper())
                {
                    string[] args = new string[] { "0" };
                    item.invokemethod("terminate", args);
                    return true;
                }
            }
            return false;
        }
    }
}


效果如下:
