打开Excel文件，刷新查询并保存C＃

Question

我正在尝试打开Excel文件，刷新其背后的查询，然后在C＃中保存并关闭该文件。

我有以下内容，但我首先在以下行收到错误：

        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();

我已添加了Microsoft.Office.Interop.Excel参考，但仍有问题，我缺少什么？

解决了以下问题：

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;

谢谢！
