No overload for method 'Open' takes '13' arguments

I’m trying to open an XLS file and then read some cell values. It doesn’t work, and I’m a little puzzled. When I try to compile the application it tells me the following message: No overload for method 'Open' takes '13' arguments However, I have checked the method and it seems that there are fifteen variables to parse in the method, but I don’t know what the other missing two are. Indeed, I am using an example posted on the Internet but it doesn’t even compile. Excel.Application ExcelObj = new Excel.Application(); ExcelObj.Visible = true; openFileDialog1.FileName = "test.xls"; // *********** Here is the call to Open a Workbook in Excel **************** Excel.Workbook theWorkbook = ExcelObj.Workbooks.Open( openFileDialog1.FileName, 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true); // get the collection of sheets in the workbook Excel.Sheets sheets = theWorkbook.Worksheets; // get the first and only worksheet from the collection // of worksheets Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);
