Is there a better way to get user status on a terminal server in C#?

I need to get user status for a specific user on a terminal server in c#.

I can do this by calling query.exe via System.Diagnostics.Process.
And then read/split the last line of the output stream.
As i do in the code example.

I need to use this in a web service, which is running on a different server, and i don't think this is the proper way to do this.

So is there a better way to do this.

public class TSTools
    public static TSInfo GetTSInfo(string server, string user)
        Process process = new Process();
        process.StartInfo.FileName = "query.exe";
        process.StartInfo.Arguments = "user " + user + " /server:" + server;
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        string lastLine = null;
        while (!process.StandardOutput.EndOfStream)
            lastLine = process.StandardOutput.ReadLine();
        TSInfo tsInfo = new TSInfo();
        if (!string.IsNullOrEmpty(lastLine))
            tsInfo.UserName = lastLine.Substring(0, 22).Trim();
            tsInfo.SessionName = lastLine.Substring(22, 17).Trim();
            tsInfo.SessionID = lastLine.Substring(39, 6).Trim();
            tsInfo.Status = lastLine.Substring(45, 9).Trim();
            tsInfo.IdleTime = lastLine.Substring(54, 10).Trim();
            tsInfo.LogonTime = lastLine.Substring(64).Trim();
            tsInfo.UserName = user;
            tsInfo.SessionName = "";
            tsInfo.SessionID = "";
            tsInfo.Status = "Offline";
            tsInfo.IdleTime = "";
            tsInfo.LogonTime = "";
        return tsInfo;
public class TSInfo
    public string UserName { get; set; }
    public string SessionName { get; set; }
    public string SessionID { get; set; }
    public string Status { get; set; }
    public string IdleTime { get; set; }
    public string LogonTime { get; set; }

This is the "Unix" way of doing things. Many Unix commands are written to have their output easily parsed and used by other programs.
I think this idea is fine. Windows is not as fast as Unix in creating processes but if your process does not call the web service too quickly, perfomance should be OK.
The advantage is that the Query.exe is already written and debugged. You could write your parse routine to be a little more flexible so blank delimiters are used in stead of the actual column locations.
