我使用“Microsoft.Office.Interop.Excel”将 Excel 转换为 PDF,但是当我的源文件大小很大(例如 10MB)时,需要很长时间...
public static bool XLSConvertToPDF(string sourcePath, string targetPath)
{
bool result = false;
XlFixedFormatType targetType = XlFixedFormatType.xlTypePDF;
object missing = Type.Missing;
Microsoft.Office.Interop.Excel.ApplicationClass application = null;
Workbook workBook = null;
try
{
application = new Microsoft.Office.Interop.Excel.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(false, missing, missing);
workBook = null;
}
if (application != null)
{
application.Quit();
application = null;
}
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
}
return result;
}
1.有没有好的建议或替代组件可以使用?
2.我知道有Adobe API,但效率如何?
顺便说一句,我也想将docx或pptx转换为pdf。非常感谢!!
