将字符串/*..rtf转换为PDF

Question

我一直试图将字符串和.rtf文档转换为PDF文档。到目前为止，我的成就参差不齐。我尝试了3种不同的方法(下面的代码)将文本转换成PDF格式。所有的em编译、运行和创建一个PDF，但是在所有的casses中，文档都被破坏了。错误：链接 (https://www.dropbox.com/s/j7sckgwm10gf5ml/PdfError.jpg?dl=0)

1. 将简单字符串转换为PDF文档 字符串msg = "dfsgfdsgdfgfdf"；System.Text.ASCIIEncoding.ASCII.GetBytes(msg)；messageBytes =新System.IO.FileStream(@"C:\file.pdf"，System.IO.FileMode.CreateNew)；System.IO.BinaryWriter writer =新BinaryWriter(流)；writer.Write(messageBytes，0，messageBytes.Length)；writer.Close()；
2. 与方法1类似： //String myString:包含从rft文件byte[] messageBytes = Encoding.UTF8.GetBytes(myString)；System.IO.File.WriteAllBytes(@"C:\foo.pdf"，messageBytes)加载的rft文档；
3. 还有更复杂的尝试3： wordToPDF() { ApplicationClass wordApplication =新ApplicationClass()；Document wordDocument = null；object paramSourceDocPath = @"C:\rtfdoc.rtf"；object paramMissing = Type.Missing；string paramExportFilePath = @"C:\pdfdoc.pdf"；WdExportFormat paramExportFormat = WdExportFormat.wdExportFormatXPS；bool paramOpenAfterExport = false；WdExportOptimizeFor paramExportOptimizeFor =WdExportOptimizeFor.wdExportOptimizeForPrint=；int = 0；int = 0；WdExportCreateBookmarks.wdExportCreateWordBookmarks；paramExportItem = WdExportItem.wdExportDocumentContent；bool paramIncludeDocProps = true；bool paramKeepIRM = true；WdExportCreateBookmarks paramCreateBookmarks =paramIncludeDocProps paramDocStructureTags = true；bool paramBitmapMissingFonts = true；bool paramUseISO19005_1 = false；尝试{ //打开源代码文档。wordDocument = wordApplication.Documents.Open( ref paramSourceDocPath，ref paramMissing，ref paramMissing，ref paramMissing)；//以指定的格式导出它。if (wordDocument != null) wordDocument paramExportFormat，paramOpenAfterExport，paramExportOptimizeFor，paramExportRange，paramStartPage，paramEndPage，paramExportItem，paramIncludeDocProps，paramKeepIRM，paramCreateBookmarks，paramDocStructureTags，paramBitmapMissingFonts，paramUseISO19005_1，ref paramMissing)；} catch (异常e) { MessageBox.Show(e.Message)；}最后{ //关闭并释放文档对象。if (wordDocument != null) { wordDocument.Close(ref paramMissing，ref paramMissing，ref paramMissing)；wordDocument = null；} //退出Word并释放ApplicationClass对象。if (wordApplication != null) { wordApplication.Quit(ref paramMissing，ref paramMissing，ref paramMissing)；wordApplication = null；} GC.Collect()；GC.WaitForPendingFinalizers()；GC.Collect()；GC.WaitForPendingFinalizers()；}}

PS:在第2和第3种情况下，我加载了一个RTF文档，其中包含特殊(德语)字符，在第1种情况下，它只是代码中看到的简单字符串，但结果都是相同的(参见上面错误的图像)。

我希望有人能帮我或者把我引向正确的方向。

对于解决方案3，请尝试更改paramExportFormat：

object paramExportFormat = Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF;
