這是一個微軟官方出的office插件。
安裝好之後，打開VS,以VS2005爲例
新建windows應用程序項目
添加以下com組件的引用
Microsoft Word 12.0 Object Library
Microsoft PowerPoint 12.0 Object Library
Microsoft Excel 12.0 Object Library
------------------------------------------------------
using Word = Microsoft.Office.Interop.Word;
using Excel = Microsoft.Office.Interop.Excel;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Core;
我們可以使用一個枚舉類型來決定生成文件的類型
Word.WdExportFormat wd = Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF;
Excel.XlFixedFormatType excelType = Microsoft.Office.Interop.Excel.XlFixedFormatType.xlTypePDF;
PowerPoint.PpSaveAsFileType ppType = Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsPDF;
這裏Word跟Excel我使用了ExportAsFixedFormat,PowerPoint我使用了SaveAs方法。
對於Word跟PowerPoint效果是一樣的，只是SaveAs方法支持的格式更多。
但是Excel似乎不支持SaveAs方法，呵呵

Word轉換方法

{
bool result;
object paramMissing = Type.Missing;

finally

wordApplication = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
Excel轉換方法
private bool Convert(string sourcePath, string targetPath, XlFixedFormatType targetType)
{
bool result;
object missing = Type.Missing;
ApplicationClass application = null;
Workbook workBook = null;
try
{
application = new ApplicationClass();
object target = targetPath;
object type = targetType;
workBook = application.Workbooks.Open(sourcePath, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing);
workBook.ExportAsFixedFormat(targetType, target, XlFixedFormatQuality.xlQualityStandard, true, false, missing, missing, missing, missing);
result = true;
}
catch
{
result = false;
}
finally
{
if (workBook != null)
{
workBook.Close(true, missing, missing);
workBook = null;
}
if (application != null)
{
application.Quit();
application = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
PowerPoint轉換方法
private bool Convert(string sourcePath, string targetPath, PpSaveAsFileType targetFileType)
{
bool result;
object missing = Type.Missing;
ApplicationClass application = null;
Presentation persentation = null;
try
{
application = new ApplicationClass();
persentation = application.Presentations.Open(sourcePath, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);
persentation.SaveAs(targetPath, targetFileType, Microsoft.Office.Core.MsoTriState.msoTrue);
result = true;
}
catch
{
result = false;
}
finally
{
if (persentation != null)
{
persentation.Close();
persentation = null;
}
if (application != null)
{
application.Quit();
application = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
如果是word文檔或者Excel文檔想要轉換xps格式，我們還可以有一種方法，那就是利用xps虛擬打印機實現。
安裝了.NetFrameWork3.5之後，默認會在系統中安裝XPS虛擬打印機，我們將其設置爲默認打印機。
Microsoft XPS Document Writer
word文檔打印爲xps
public void PrintWord(string wordfile)
{
oWord.ApplicationClass word = new oWord.ApplicationClass();
Type wordType = word.GetType();
//打開WORD文檔
oWord.Documents docs = word.Documents;
Type docsType = docs.GetType();
object objDocName = wordfile;
oWord.Document doc = (oWord.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { objDocName, true, true });
//打印輸出到指定文件
//可以使用 doc.PrintOut();方法,次方法調用中的參數設置較繁瑣,建議使用 Type.InvokeMember 來調用時可以不用將PrintOut的參數設置全,只設置4個主要參數
Type docType = doc.GetType();
object printFileName = wordfile + ".xps";
docType.InvokeMember("PrintOut", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { false, false, oWord.WdPrintOutRange.wdPrintAllDocument, printFileName });
//退出WORD
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);
}
Excel利用虛擬打印機轉換爲xps
public void PrintExcel(string execlfile)
{
Excel.ApplicationClass eapp = new Excel.ApplicationClass();
Type eType = eapp.GetType();
Excel.Workbooks Ewb = eapp.Workbooks;
Type elType = Ewb.GetType();
object objelName = execlfile;
Excel.Workbook ebook = (Excel.Workbook)elType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, Ewb, new Object[] { objelName, true, true });
object printFileName = execlfile + ".xps";
Object oMissing = System.Reflection.Missing.Value;
ebook.PrintOut(oMissing, oMissing, oMissing, oMissing, oMissing, true, oMissing, printFileName);
eType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, eapp, null);
}
，同樣，如果系統安裝了PDF虛擬打印機，如5D PDF之類的，我們也可以將其設置爲默認打印機以達到轉換爲PDF格式的目的
我們可以將這些方法放在windows service裏面，實現文檔的後臺轉換。
