在 C# 中将 Doc 转换为 PDF。

如何使用ASP.NET C＃将.doc文件转换为.pdf文件。我不能使用任何第三方组件。

代码应该是：

  1. C＃或VB.NET
  2. 与VS 2005兼容。（如果不是，请仍然发布您的回复，我将手动转换为VS 2005）

如果有任何问题，请告诉我。

谢谢！

//Add Office Library
using Word = Microsoft.Office.Interop.Word;
object str_letter_path = @"D:\DOCTEST.doc";
object outputFilePathPDF = @"D:\PDFTEST.PDF";
Word.Application wordApp = new Word.Application();
wordApp.Visible = false;
wordApp.ScreenUpdating = false;
object oMissing = System.Reflection.Missing.Value;
object fileFormat = Word.WdSaveFormat.wdFormatPDF;
Word.Document doc = wordApp.Documents.Open(ref str_letter_path, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing);
            doc.Activate();
            doc.SaveAs(ref outputFilePathPDF,
                            ref fileFormat, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing);
            object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
            if (doc != null)
                ((Word._Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
            ((Microsoft.Office.Interop.Word._Application)wordApp).Quit(ref saveChanges, ref oMissing, ref oMissing);

                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                       ref Unknown, ref Unknown);
            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message);
            }
            finally
            {
                if (MSdoc != null)
                {
                    MSdoc.Documents.Close(ref Unknown, ref Unknown, ref Unknown);
                    //WordDoc.Application.Quit(ref Unknown, ref Unknown, ref Unknown);
                }               
                // for closing the application
                WordDoc.Quit(ref Unknown, ref Unknown, ref Unknown);
            }
        }

前提条件：

  • 带有（默认情况下将安装主要互操作性程序集的）MS word2007。
  • 插件SaveAsPDFandXPS（来自MS Site的免费插件）

确保您引用了Word.12。
它将自动向您的引用中添加Microsoft.Office.interop.word。按照这些步骤使用其他Office应用程序。
（注意：您应该已经安装了VS 2005 Office工具第二版运行时（VSTO 2005 SE）（x86）
