How do I determine the owner of a process in C#?

I am looking for a process by the name of "MyApp.exe" and I want to make sure I get the process that is owned by a particular user.

I use the following code to get a list of the processes:

Process[] processes = Process.GetProcessesByName("MyApp");

This gives me a list of processes, but there does not appear to be a way in the Process class to determine who owns that process? Any thoughts on how I can do this?

From stackoverflow

• You can use WMI to get the user owning a certain process:

  By process id:

  public string GetProcessOwner(int processId)
  {
      string query = "Select * From Win32_Process Where ProcessID = " + processId;
      ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
      ManagementObjectCollection processList = searcher.Get();
  
      foreach (ManagementObject obj in processList)
      {
          string[] argList = new string[] { string.Empty, string.Empty };
          int returnVal = Convert.ToInt32(obj.InvokeMethod("GetOwner", argList));
          if (returnVal == 0)
          {
              // return DOMAIN\user
              return argList[1] + "\\" + argList[0];
          }
      }
  
      return "NO OWNER";
  }
  

  By process name (finds the first process only, adjust accordingly):

  public string GetProcessOwner(string processName)
  {
      string query = "Select * from Win32_Process Where Name = \"" + processName + "\"";
      ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
      ManagementObjectCollection processList = searcher.Get();
  
      foreach (ManagementObject obj in processList)
      {
          string[] argList = new string[] { string.Empty, string.Empty };
          int returnVal = Convert.ToInt32(obj.InvokeMethod("GetOwner", argList));
          if (returnVal == 0)
          {
              // return DOMAIN\user
              string owner = argList[1] + "\\" + argList[0];
              return owner;       
          }
      }
  
      return "NO OWNER";
  }
  

  MikeHerrera : In your second method, your nested if contains a string, owner. I believe you were intending to return that string, instead.

  0xA3 : Thanks Mike, fixed it.

• Unfortunately there's no native .Net way of getting the process owner.

  Have a look at these for a potential solution:
