问题： Excel转PDF编程中ExportAsFixedFormat问题
描述: 在MSDN上看Excel2007可以将xlsx文件转换为pdf文件，还有参考编码：
http://msdn.microsoft.com/en-us/library/bb407651(v=office.12).aspx
于是就照着这个编了一通，结果调试时候报错，ex.message：出现异常值不在预期的范围内
代码如下，很简单，就是把网站根目录下的一个.xlsx文件转为pdf，源文件在，打开正常，但是保存时候出错。
期待高手看看，哪里写的不对，先谢谢拉！

解决方案1: Microsoft.Office.Interop.Excel.XlFixedFormatType paramExportFormat = Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF;
Microsoft.Office.Interop.Excel.XlFixedFormatQuality paramExportQuality = Microsoft.Office.Interop.Excel.XlFixedFormatQuality.xlQualityStandard;
应该是enum类型
enum Microsoft.Office.Interop.Excel.XlFixedFormatType paramExportFormat = enum Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF;
enum Microsoft.Office.Interop.Excel.XlFixedFormatQuality paramExportQuality = enum Microsoft.Office.Interop.Excel.XlFixedFormatQuality.xlQualityStandard;
