我正在开发 Sharepoint Web 部件。我已经自定义了 Sharepoint 服务器功能区。 Sharepoint 服务器功能区现在包含一个按钮。单击此按钮后，我将 sharepoint 库中的 xlsx 文件下载到我的本地驱动器之一。现在我想将这个下载的 xlsx 文件转换成 pdf 文件。然后我想将此pdf文件上传到sharepoint中的一个文档库。为了自定义服务器功能区和处理按钮回发，我使用以下链接，其中提供了代码示例供下载
Customizing and Extending the SharePoint 2010 Server Ribbon
代码示例对我来说工作正常。我已将 xlsx 文件下载到本地文件夹。现在我想将本地文件夹中下载的 xlsx 文件转换为 pdf 文件所以我使用以下链接
上面链接中给出的代码示例也是我在控制台应用程序中的工作文件。我能够在控制台应用程序中将 xlsx 文件转换为 pdf 文件。但是当我将代码复制并粘贴到共享点项目中时，它不起作用。我无法理解为什么相同的代码在 Sharepoint 项目中不起作用？代码如下
SautinSoft.UseOffice u = new SautinSoft.UseOffice();
//Path to any local file
string inputFilePath = "D:\\a.xlsx";
//string inputFilePath = "http://shailesh-pc/TemplateInvoice/Template.xlsx";
//Path to output resulted file
string outputFilePath = "D:\\afadfasfd.pdf";
//string outputFilePath = "http://shailesh-pc/Invoice/aa.xlsx";
//Prepare UseOffice .Net, loads MS Excel in memory
int ret = u.InitExcel();
//Return values:
//0 - Loading successfully
//1 - Can't load MS Excel library in memory
if (ret == 1)
return;
//Converting
ret = u.ConvertFile(inputFilePath, outputFilePath, SautinSoft.UseOffice.eDirection.XLSX_to_PDF);
//Release MS Excel from memory
u.CloseExcel();
//0 - Converting successfully
//1 - Can't open input file. Check that you are using full local path to input file, URL and relative path are not supported
//2 - Can't create output file. Please check that you have permissions to write by this path or probably this path already used by another application
//3 - Converting failed, please contact with our Support Team
//4 - MS Office isn't installed. The component requires that any of these versions of MS Office should be installed: 2000, XP, 2003, 2007 or 2010
if (ret == 0)
{
//Show produced file
System.Diagnostics.Process.Start(outputFilePath);
}
在共享点项目中，我在 int ret = u.InitExcel(); 处得到值 0 但在行 ret = u.ConvertFile(inputFilePath, outputFilePath, SautinSoft.UseOffice.eDirection.XLSX_to_PDF); 在共享点项目中。为什么会这样。 sharepoint 项目是否存在任何问题，因此他们无法将 xlsx 文件转换为 pdf？你能告诉我在 Sharepoint 中将 xlsx 文件转换为 pdf 需要做什么吗？能否请您提供任何代码或链接，通过它我可以将 xlsx 文件转换为 pdf 文件？
请您参考如下方法:
请注意，Microsoft 不建议在此类情况下使用 Office 自动化:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
您可以在以下主题中查看更多详细信息:http://support.microsoft.com/kb/257757 .因此，最好考虑替代方案。
