请教 pdf和word互转的问题

[xx2]

请教下，
asp.net 如何把 pdf和word互相转换呢？

另外，把一个word 搜索一个关键字 比如 aaa , 然后把名字改成 aaa1 这个可以吗？

Word本身另存为就可以存为pdf。。。。。。我没阅读器，你试试再另存为存回来撒，直接另存为就行了

[大然然]

不需要第三方，系统自带的Microsoft.Office.Interop.Word;就可以

/// <summary>
/// 转换word 成PDF文档
/// </summary>
/// <param name="docFileFullName">原文件路径</param>
/// <param name="pdfSaveFullName">pdf文件输出路径</param>
/// <returns>true 成功</returns>
public static bool ConverterToPdf(string docFileFullName, string pdfSaveFullName)
{
if(File.Exists(pdfSaveFullName))
return true;
Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.Application();
Document document = null;
object missing = System.Reflection.Missing.Value;
object saveChanges = null;

try
{
object lobjFileName = (object)docFileFullName;
document = application.Documents.Open(ref lobjFileName, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
document.Activate();

object lobjOutPutFileName = (object)pdfSaveFullName;
object lobjFileFormat = WdSaveFormat.wdFormatPDF; //保存格式为PDF

//创建目录
string saveDir = Path.GetDirectoryName(pdfSaveFullName);
if(!Directory.Exists(saveDir))
Directory.CreateDirectory(saveDir);

document.SaveAs(ref lobjOutPutFileName, ref lobjFileFormat, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

saveChanges = WdSaveOptions.wdDoNotSaveChanges;

((_Document)document).Close(ref saveChanges, ref missing, ref missing);
document = null;
((_Application)application).Quit(ref saveChanges, ref missing, ref missing);
application = null;
}
catch(Exception ex)
{

return false;
}
finally
{
if(document != null)
{
((_Document)document).Close(ref saveChanges, ref missing, ref missing);
Marshal.ReleaseComObject(document);
document = null;
}
if(application != null)
{
((_Application)application).Quit(ref saveChanges, ref missing, ref missing);
Marshal.ReleaseComObject(application);
application = null;
}

GC.Collect();
GC.WaitForPendingFinalizers();
}
return true;
}

有第三方的命令行 pdf2doc可以转换，转换pdf可以用虚拟打印机，调用 -p参数打印。
