Question

我有一个sql server 2008作业，用dll创建excel文件。 dll使用xmlwriter创建excel文件。它正在创建xml电子表格2003文件

问题是文件太大了250mb

CREATE  ASSEMBLY [myclr]
AUTHORIZATION [dbo]
FROM  'myclr.dll'
WITH PERMISSION_SET = unsafe;
GO

我的尝试：

从xmlwriter中删除了一些xml属性，但仍然太大
openxml

使用Windows.base.dll的问题openxml无法注册到sql server，因为它不是supported dlls

microsoft.office.interop

客户端不想设置办公室到服务器

现在我的解决方案是我将编写一个Windows服务，它将打开并保存为excel文件。我用microsoft.office.interop写的但我需要另一种方法来做到这一点。

        Microsoft.Office.Interop.Excel.ApplicationClass _Excel = null;
        Microsoft.Office.Interop.Excel.Workbook WB = null;
        // Microsoft.Office.Interop.Excel.Worksheet WS = null;
        object missing = Type.Missing;
        try
        {

            _Excel = new Microsoft.Office.Interop.Excel.ApplicationClass();
            WB = _Excel.Workbooks.Open(path,
                missing, missing, missing, missing,
                missing, missing, missing, missing,
                missing, missing, missing, missing,
                missing, missing);


        }
        catch (Exception ex)
        {
            WB.Close(false, missing, missing);

            throw;
        }
        finally
        {
            GC.Collect();
            GC.WaitForPendingFinalizers();
            _Excel.DisplayAlerts = false;
            WB.SaveAs(path, 
                      Microsoft.Office.Interop.Excel.XlFileFormat.xlExcel8,
                      missing, missing, missing, missing,                                  
                      Microsoft.Office.Interop.Excel.
                      XlSaveAsAccessMode.xlNoChange,  
                      Microsoft.Office.Interop.Excel.
                      XlSaveConflictResolution.xlLocalSessionChanges,
                    missing, missing, missing, missing);
            _Excel.Quit();

        }

openxml

  using (SpreadsheetDocument ssd = 
                SpreadsheetDocument.Open("myfile.xls", true)) 
    {
        WorkbookPart wbPart = ssd.WorkbookPart;
        WorksheetPart worksheetPart = wbPart.WorksheetParts.First();


        worksheetPart.Worksheet.Save();
        wbPart.Workbook.Save();
        ssd.Close();
    }

文件包含损坏的数据

注意：很长的抱歉，没有土豆

保存为具有不同格式的excel文件，xml电子表格2003到xls或xlsx
