如何使用C＃以编程方式在excel中选择选项卡

Question

When I open a workbook in excel it goes to the last tab and scroll position I had open. I want to write some c# code to open excel workbook and select the first tab, and scroll to cell A1, so when it opens it will be on that that worksheet. all solutions I tried so far produced exceptions:

worksheet.Select(Type.Missing)
(worksheet as Excel._Worksheet).Activate();
excelApp.Goto(worksheet.get_range("A1", Type.Missing), true);

Answer 1

Try:

Microsoft.Office.Interop.Excel.Worksheet firstSheet = (Microsoft.Office.Interop.Excel.Worksheet)excelApp.ActiveWorkbook.Worksheets[1];
firstSheet.Select(System.Reflection.Missing.Value);
excelApp.get_Range("$A1", hmissing).Select();
