Proper way to check worksheet is exist in workbook

I'm writing below codes to create and save workbook and checking sheet is existing in workbook. I didn't test it yet, before that i'd like to ask you what's proper way to declare them. Especially for sheet check and creating new workbook.

    public static bool CreateWorkbook(string filename)
        {
            try
            {
                using (ClosedXML.Excel.XLWorkbook workbook = new ClosedXML.Excel.XLWorkbook())
                {
                    ClosedXML.Excel.IXLWorksheet worksheet = workbook.Worksheets.Add(sheetName: "Default");
                    SaveAs(workbook, filename);
                }

                return true;

            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                throw;
            }

        }

  public static bool SaveAs(ClosedXML.Excel.XLWorkbook workbook, string filename)
        {
            try
            {
                workbook.SaveAs(filename);
                return true;
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                throw;
            }
        }

  public static bool IsSheetExists(ClosedXML.Excel.XLWorkbook workbook, string sheetname)
        {
            try
            {
                bool result = false;

                foreach (ClosedXML.Excel.IXLWorksheet worksheet in workbook.Worksheets)
                {
                    if (worksheet.Name == sheetname)
                    {
                        result = true;
                        break;
                    }
                }

                return result;
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                throw;
            }
        }
