List domain users with wmi - windows

Question

I want to list all users of a Windows domain with WMI in C#.
Can someone help me?
Here is my code:
try
{
ConnectionOptions connection = new ConnectionOptions();
connection.Username = user;
connection.Authority = "ntlmdomain:" + domain;
connection.Password = pwd;
SelectQuery query = new SelectQuery("SELECT * FROM Win32_UserAccount");
ManagementScope scope = new ManagementScope(#"\\FullComputerName\\root\\CIMV2", connection);
scope.Connect();
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("Account Type: " + queryObj["AccountType"]);
Console.WriteLine("Caption: " + queryObj["Caption"]);
Console.WriteLine("Description: " + queryObj["Description"]);
Console.WriteLine("Disabled: " + queryObj["Disabled"]);
Console.WriteLine("Domain: " + queryObj["Domain"]);
Console.WriteLine("Full Name: " + queryObj["FullName"]);
Console.WriteLine("Local Account: " + queryObj["LocalAccount"]);
Console.WriteLine("Lockout: " + queryObj["Lockout"]);
Console.WriteLine("Name: " + queryObj["Name"].ToString());
Console.WriteLine("Password Changeable: " + queryObj["PasswordChangeable"]);
Console.WriteLine("Password Expires: " + queryObj["PasswordExpires"]);
Console.WriteLine("Password Required: " + queryObj["PasswordRequired"]);
Console.WriteLine("SID: " + queryObj["SID"]);
Console.WriteLine("SID Type: " + queryObj["SIDType"]);
Console.WriteLine("Status: " + queryObj["Status"]);
Console.WriteLine("");
}
}
catch (ManagementException err)
{
Console.WriteLine("An error occured while querying for WMI data: " + err.Message);
}
catch (System.UnauthorizedAccessException unauthorizedErr)
{
Console.WriteLine("Connection error " + "(user name or password might be incorrect): " + unauthorizedErr.Message);
}

There's a typo in the namespace path in your ManagementScope constructor:
ManagementScope scope = new ManagementScope(#"\\FullComputerName\\root\\CIMV2", connection);
The string should be either #"\\FullComputerName\root\CIMV2" or "\\\\FullComputerName\\root\\CIMV2".
Note that you cannot specify the user account for local connections. So if FullComputerName is a local computer, use this instead:
ManagementScope scope = new ManagementScope("root\\CIMV2");
