使用C#中的savefiledialog类保存excel文件

Question

我需要创建并保存Excel文件,而不在代码中通知路径和文件名.所以我可以使用savefiledialog来显示保存框以输入路径和文件名,但我无法正确使用它.我尝试使用worksheet.saveas,但是这个类没有显示保存框来输入路径和文件名.如何使用该保存框保存excel文件？

Answer 1

它的基本机制是这样的:

public void SaveExcelWorkBook()
{
   OpenFileDialog openDlg = new OpenFileDialog();
   openDlg.InitialDirectory = @"C:\";
   openDlg.ShowDialog();
   string path = openDlg.FileName;

   if (openDlg.ShowDialog() == DialogResult.OK)
   {
      try
      {
         Application excelApp = new Application();
         Workbook workBook = excelApp.Workbooks.Open(path);
         Worksheet workSheet = (Worksheet)workBook.Worksheets[1];

         // Do your work here inbetween the declaration of your workbook/worksheet  
         // and the save action below.

         workBook.SaveAs(/*path to save it to*/);  // NOTE: You can use 'Save()' or 'SaveAs()'
         workBook.Close(); 
      }

      catch (Exception ex)
      {
      }
   }
}

我想我还应该提到Interop对象是不受管理的,所以你需要确保在调用后释放它们.Close().这是一个例子:

Marshal.ReleaseComObject(workBook);
