Question

我正在尝试通过C＃保存excel文件，但该文件未保存在我使用变量指定的位置。以下是我的代码：

Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();

if (xlApp == null)
{
    //MessageBox.Show("Excel is not properly installed!!");
    return;
}

Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;

if (!System.IO.File.Exists(FileName))
{
    xlWorkBook = xlApp.Workbooks.Add(misValue);
}
else
{
    xlWorkBook = xlApp.Workbooks.Open(FileName, 0, false, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", true, false, 0, true, 1, 0);
}

xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

//一些代码

xlApp.DisplayAlerts = false;
xlWorkBook.SaveAs(FileName, Type.Missing,Type.Missing,Type.Missing,false,Type.Missing,XlSaveAsAccessMode.xlExclusive,Type.Missing,Type.Missing,Type.Missing);
xlWorkBook.Close(true, FileName, misValue);
xlApp.Application.Quit();
xlApp.Quit();

我在这里做错了什么？我感到非常沮丧，不能保存在我想要的地方。任何帮助将不胜感激

根据@mohammedlok关于确保没有内存泄漏的评论，我总是使用try-catch-finally方法来确保excel进程无论如何都会一直关闭。下面的示例代码对我有用：

Application excelApp = new Application();
Workbook excelWorkbook = null;
string excelFilePath = "C:\\Users\\Desktop\\Sample.xlsx";

try
{
  //Create a workbook
  excelWorkbook = excelApp.Workbooks.Add(Type.Missing);

  //Make and name a worksheet
  activeWorksheet = excelWorkbook.ActiveSheet;

  //Write in cell B3 of the worksheet
  Range r = activeWorksheet.get_Range("B3", Type.Missing);
  r.Value2 = "This is a sample.";

  //Save the workbook
  excelWorkbook.SaveAs(excelFilePath, Type.Missing, Type.Missing, Type.Missing, false, Type.Missing, XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing);  
}
catch (Exception ex)
{
  throw ex;
}
finally
{
  if (excelWorkbook != null)
  {
     excelApp.Calculation = XlCalculation.xlCalculationAutomatic;
     excelApp.DisplayAlerts = false;
     excelWorkbook.RefreshAll();
     excelWorkbook.Close(true, excelFilePath);
     excelApp.Quit();
  }
}

Excel文件未保存在指定位置
