我无法使用excel interop在C＃中选择范围。请让我知道我在这里做错了什么。我是很新的卓越的互操作

static void Main(string[] args) 
    { 
     Excel.Application xlApp = new Excel.Application(); 
     Excel.Workbook xlWorkbook = xlApp.Workbooks.Open("D:\\s1.xlsx"); 

     Excel.Range xlTestRange; 
     Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[2]; 

     xlTestRange = xlWorksheet.UsedRange; 
     xlTestRange.Select(); 
     xlWorkbook.Save(); 
     xlWorkbook.Close(); 
     xlApp.UserControl = true; 
     xlApp.Quit(); 


    }

下面的代码在LINQPad工作对我来说：

var xlApp = new Excel.Application(); 
var xlWorkbook = xlApp.Workbooks.Open(@"path-to-excel-file"); 
var xlWorksheet = (Excel.Worksheet)xlWorkbook.Sheets[1]; 

var xlTestRange = xlWorksheet.UsedRange; 
xlTestRange.Select(); 
xlWorkbook.Save(); 

xlWorkbook.Close(); 
xlApp.Quit();
