Question

I am working with the FAXCOMEXLib example that microsoft posted awhile back and am trying to port it to C#. I am having trouble with a call that returns a Variant type which holds a string array. “jobID = objFaxDocument.ConnectedSubmit(objFaxServer);”

The procedure returns a messagebox which shows “System.String[]”. I seem to recall from working with Delphi which also uses variants, that one property of the variant is just a string which shows what it is storing. Maybe this is what is going on here. But anyway, how can i get this string array out and convert it into something c# would understand?

Thanks

            FAXCOMEXLib.FaxDocument objFaxDocument = new FAXCOMEXLib.FaxDocument();
        FAXCOMEXLib.FaxServer objFaxServer = new FAXCOMEXLib.FaxServer();

        object jobID;


        try {
            //Connect to the fax server
            objFaxServer.Connect("");

            // skipping some code, see MS example in URL above

            jobID = objFaxDocument.ConnectedSubmit(objFaxServer);

            MessageBox.Show("The Job ID is :" + jobID);

Answer 1

A simple cast will do the trick:

object objIDs = objFaxDocument.ConnectedSubmit(objFaxServer);
string[] IDs = (string[])objID;
