How to get a C# method to return multiple values

I am trying to refine my C# code to return two values.
trxDateToProcess  is a datevalue and
payPeriodToProcess  is an integer

What would be the proper way to get this method to return both values? The second record in the text file has both values. Do I setup a class to do this?

        private void GetTrxDatePayPeriodToProcess()
        {
            int rc = 0;
            string[] format = { "yyyyMMdd" };

            using (var tfp = new TextFieldParser(Model.importFilename))
            {
                /* Set up the comma as the delimieters used in the file */
                tfp.Delimiters = new string[] { "," };

                /* True if data fields can be in double quotes */
                tfp.HasFieldsEnclosedInQuotes = true;

                /* This means this file is a delimted file and NOT fixed width */
                tfp.TextFieldType = FieldType.Delimited;

                /* Remove white spaces from beginning and ending of each field */
                tfp.TrimWhiteSpace = true;

                while (rc < 2)
                {
                    var data = tfp.ReadFields();                                /* Read the payroll import file records to get the pay period*/

                    if (DateTime.TryParseExact(data[0], format, System.Globalization.CultureInfo.InvariantCulture, System.Globalization.DateTimeStyles.None, out dateValue))
                    {
                        Model.trxDateToProcess = dateValue;                                                                                 /* Trx_Date */
                    }
                    else
                    {
                        Model.trxDateToProcess = Model.badDate;
                    }

                    Model.payPeriodToProcess = data[4];

                    rc += 1;
                }
            }
        }
