c#获取进程用户名

Question

如题，我想通过c#做一个进程查看工具，但是不知道要如何获得启动进程的用户名？请高手指教

Answer 1

用 Process.GetProcesses() 找到进程实例后，Process 类型上就有对应的 StartInfo 属性，然后用 UserName 属性可以直接得到用户名。

Answer 2

Process.GetProcesses() 获取进程集合，遍历就行了

Answer 3

using System.Diagnostics;

using System.Management;

 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;
        }


 private void button1_Click(object sender, EventArgs e)
        {
          
            foreach (Process p in Process.GetProcesses())
            {
                Console.Write(p.ProcessName);
                MessageBox.Show(p.ProcessName + "---" + GetProcessUserName(p.Id));

            }



        }

Answer 4

得到的所有进程的username都是空的

Answer 5

确实是空的，看来我得办法行不通。

using System.Diagnostics;

using System.Management;

 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;
        }


 private void button1_Click(object sender, EventArgs e)
        {
          
            foreach (Process p in Process.GetProcesses())

                Console.Write(p.ProcessName);
                MessageBox.Show(p.ProcessName + "---" + GetProcessUserName(p.Id));

            }



        }

你好！

上面的方法能正确获取到用户名。

Answer 7

谢谢，确实能够读出来；不过我想每次获取到所有进程的用户名，用这个函数效率太慢了，有没有什么优化方法吗？

Answer 8

你好！

我查了一下资料并没有找到其它可以得到用户名的方式。我把上面的过程优化了一下，效率提高了一倍多，希望对你有帮助。

class ProcessInfo
{
    public string Id { get; set; }
    public string Name { get; set; }
    public string UserName { get; set; }

    public ProcessInfo(string id, string name, string userName)
    {
        this.Id = id;
        this.Name = name;
        this.UserName = userName;
    }
}

static void Main(string[] args)
{
    DateTime begin = DateTime.Now;

    List<ProcessInfo> processInfoCollection = new List<ProcessInfo>();

    ManagementObjectCollection queryCollection = new ManagementObjectSearcher("SELECT * FROM Win32_Process").Get();

    foreach (ManagementObject mo in queryCollection)
    {
        ManagementBaseObject inPar = mo.GetMethodParameters("GetOwner"); ;
        ManagementBaseObject outPar = mo.InvokeMethod("GetOwner", inPar, null);

        string userName = (outPar["User"] == null) ? string.Empty : outPar["User"].ToString();
        processInfoCollection.Add(new ProcessInfo(mo["ProcessID"].ToString(), mo["Name"].ToString(), userName));
    }

    foreach (ProcessInfo p in processInfoCollection)
    {
        Console.WriteLine("ProcessID      : {0}", p.Id);
        Console.WriteLine("ProcessName    : {0}", p.Name);
        Console.WriteLine("ProcessUserName: {0}", p.UserName);
        Console.WriteLine();
    }

    Console.WriteLine("CostSeconds: {0}", (DateTime.Now - begin).TotalSeconds.ToString("f2"));
    Console.ReadKey();
}

Answer 9

谢谢，不过就是有点看不太懂。能给讲讲吗？还有，通过这个还能获取到进程的其它信息吗？比如路径、内存之类的
