轉(zhuǎn)換功能是通過(guò)調(diào)用安裝了
轉(zhuǎn)換XPS和PDF的AddIn的Office2007對(duì)象模型完成的. 代碼支持Office 2007支持的一切文件格式:
Office 2007組件
擴(kuò)展名
Word
DOC, DOCX, DOCM, DOTX, DOTM, DOT, TXT, RTP, RTF
Excel
XLS, XLSX, XLSM, XML
PowerPoint
PPT, PPTX, PPTM, POTX, PPSX, PPSM, POTM
添加對(duì)三個(gè)組件的引用：
這里使用一個(gè)枚舉類(lèi)型來(lái)來(lái)決定生成文件的類(lèi)型,包括：
其實(shí)可以使用個(gè)方法來(lái)實(shí)現(xiàn)這個(gè)功能，這里Word和Excel我使用了ExportAsFixedFormat，PowerPoint使用了SaveAs，對(duì)于Word和PowerPoint效果是一樣的。只是SaveAs支持的格式更多, 但我發(fā)現(xiàn)似乎Excel不支持SaveAs.
Word轉(zhuǎn)換代碼:
private bool Convert(string sourcePath, string targetPath, Word.WdExportFormat exportFormat)
{
bool result;
object paramMissing = Type.Missing;

wordApplication = null;

GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
Excel轉(zhuǎn)換代碼：
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 type = targetType;
workBook = application.Workbooks.Open(sourcePath, missing, missing, missing, missing, missing,
missing, missing, missing, missing, missing, missing, missing, missing, missing);

result = true;
}
catch
{

}
finally
{

}
if (application != null)
{
application.Quit();
application = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
PowerPoint轉(zhuǎn)換代碼：
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;
}
感謝同事Hong的協(xié)助,把這部分功能實(shí)現(xiàn)，現(xiàn)在share給大家，希望為需要的朋友節(jié)省時(shí)間.
