打開Excel文件，刷新查詢並保存C＃

Question

我想打開一個Excel文件，刷新它後面的查詢，然後保存並關閉C＃文件。

我有以下的，但我在下面的行收到錯誤首先是

 object _missingValue = System.Reflection.Missing.Value; 
     Application excel = new Application(); 
     Workbook theWorkbook = excelFile.Workbooks._Open(txtLocation.Text, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue); 
     Sheets sheets = (Sheets)theWorkbook.Worksheets; 
     theWorkbook.RefreshAll(); 
     theWorkbook.Save(); 
     excel.Quit(); 

我已經添加了的Microsoft.Office.Interop.Excel引用，但仍然有問題，我錯過了什麼？

解決下列要求：

object _missingValue = System.Reflection.Missing.Value; 
      Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application(); 
      Workbook theWorkbook = excel.Workbooks.Open(txtLocation.Text, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue, _missingValue); 
Sheets sheets = (Sheets)theWorkbook.Worksheets; 
theWorkbook.Save(); 
excel.Quit(); 
return true; 

謝謝！
