How Can I Get the Owner of a Process in C# Using WMI?

Get process owner in C#

Accurate control and security management require access to process owner information. This article describes a method to obtain the owner of a process using Windows Management Instrumentation (WMI).

First, you need to quote System.Management.dll. This will allow you to use the WMI framework.

Get owner by process ID

The following code snippet gets the owner of a process based on its process ID:

<code class="language-csharp">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)
        {
            // 返回 DOMAIN\user 格式
            return argList[1] + "\" + argList[0];
        }
    }

    return "NO OWNER";
}</code>

Get owner by process name

To get the owner by process name, you can use the following code snippet:

<code class="language-csharp">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)
        {
            // 返回 DOMAIN\user 格式
            string owner = argList[1] + "\" + argList[0];
            return owner;
        }
    }

    return "NO OWNER";
}</code>
