1、WPS安裝，最好用這個版本別的版本不清楚，安裝Pro Plus2016版本。
https://ep.wps.cn/product/wps-office-download.html
2、添加相關的引用：wpsapiex.dll,etapi.dll,wppapi.dll,wpsapi.dll，目前就發現這幾個
3、代碼類如下
/// <summary> /// WPS文件轉Pdf類 /// </summary> public class ToPdfHelper : IDisposable { /// <summary> /// 是否殺死全部WPS程序 /// </summary> public bool IsKillAllWps = false; //Wps的動態對象 dynamic wps; /// <summary> /// 初始化類基礎信息 /// </summary> /// <param name="FilePath">文件路徑</param> /// <param name="IsKillAllWps">轉換完成后是否殺死全部WPS應用</param> public ToPdfHelper(string FilePath, bool IsKillAllWps = false) { if (File.Exists(FilePath)) { this.IsKillAllWps = IsKillAllWps; this.FilePath = FilePath; string Extension = Path.GetExtension(FilePath).ToLower();//擴展名 ".aspx" switch (Extension) { case "xls": Extension = "KET.Application"; break; case "xlsx": Extension = "KET.Application"; break; case "ppt": Extension = "KWPP.Application"; break; case "pptx": Extension = "KWPP.Application"; break; default: Extension = "KWps.Application"; break; } Type type = Type.GetTypeFromProgID(Extension); if (type == null) { Extension = "wps.Application"; type = Type.GetTypeFromProgID("wps.Application"); } wps = Activator.CreateInstance(type); //比較完整的一些 //WPS文字 KWPS.Aplication //WPS的Excel KET.Application //WPS的演示文檔 KWPP.Application //Word Word.Application //Excel Excel.Application //Powerpoint Powerpoint.Application } else { throw new Exception("找不到原文件，請檢查！"); } } /// <summary> /// 源文件路徑 /// </summary> public string FilePath { get; set; } /// <summary> /// 使用wps將Word轉PDF /// </summary> /// <param name="TargetPath">目標文件路徑，不傳默認在源文件的所屬目錄</param> /// <returns>Pdf文件路徑</returns> public string WordWpsToPdf(string TargetPath = "") { if (string.IsNullOrEmpty(FilePath)) { throw new Exception("請傳入文件路徑"); } //如果沒傳入文件路徑就默認使用源目錄 if (string.IsNullOrEmpty(TargetPath)) { TargetPath = Path.ChangeExtension(FilePath, "pdf"); } try { //忽略警告提示 wps.DisplayAlerts = false; //用wps 打開word不顯示界面 dynamic doc = wps.Documents.Open(FilePath, Visible: false); //保存為Pdf doc.ExportAsFixedFormat(TargetPath, Word.WdExportFormat.wdExportFormatPDF); //設置隱藏菜單欄和工具欄 //wps.setViewerPreferences(PdfWriter.HideMenubar | PdfWriter.HideToolbar); doc.Close(); doc = null; } catch (Exception e) { throw e; } finally { Dispose(); } return TargetPath; } /// <summary> /// 使用wps將xls轉PDF /// </summary> /// <param name="TargetPath">目標文件路徑，不傳默認在源文件的所屬目錄</param> /// <returns>Pdf文件路徑</returns> public string XlsWpsToPdf(string TargetPath = "") { if (string.IsNullOrEmpty(FilePath)) { throw new Exception("請傳入文件路徑"); } //如果沒傳入文件路徑就默認使用源目錄 if (string.IsNullOrEmpty(TargetPath)) { TargetPath = Path.ChangeExtension(FilePath, "pdf"); } try { XlFixedFormatType targetType = XlFixedFormatType.xlTypePDF; object missing = Type.Missing; //忽略警告提示 wps.DisplayAlerts = false; //xls 轉pdf dynamic doc = wps.Application.Workbooks.Open(FilePath, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing); //保存為Pdf doc.ExportAsFixedFormat(targetType, TargetPath, XlFixedFormatQuality.xlQualityStandard, true, false, missing, missing, missing, missing); //設置隱藏菜單欄和工具欄 //wps.setViewerPreferences(PdfWriter.HideMenubar | PdfWriter.HideToolbar); doc.Close(); doc = null; } catch (Exception e) { throw e; } finally { Dispose(); } return TargetPath; } /// <summary> /// 使用ppt將xls轉PDF /// </summary> /// <param name="TargetPath">目標文件路徑，不傳默認在源文件的所屬目錄</param> /// <returns>Pdf文件路徑</returns> public string PptWpsToPdf(string TargetPath = "") { if (string.IsNullOrEmpty(FilePath)) { throw new Exception("請傳入文件路徑"); } //如果沒傳入文件路徑就默認使用源目錄 if (string.IsNullOrEmpty(TargetPath)) { TargetPath = Path.ChangeExtension(FilePath, "pdf"); } try { //忽略警告提示 wps.DisplayAlerts = false; //ppt 轉pdf dynamic doc = wps.Presentations.Open(FilePath, MsoTriState.msoCTrue, MsoTriState.msoCTrue, MsoTriState.msoCTrue); object missing = Type.Missing; //doc.ExportAsFixedFormat(pdfPath, PpFixedFormatType.ppFixedFormatTypePDF, // PpFixedFormatIntent.ppFixedFormatIntentPrint, // MsoTriState.msoCTrue, PpPrintHandoutOrder.ppPrintHandoutHorizontalFirst, // PpPrintOutputType.ppPrintOutputBuildSlides, // MsoTriState.msoCTrue, null, PpPrintRangeType.ppPrintAll,"", // false, false, false, false, false, missing); //保存為Pdf doc.SaveAs(TargetPath, PowerPoint.PpSaveAsFileType.ppSaveAsPDF, MsoTriState.msoTrue); //設置隱藏菜單欄和工具欄 //wps.setViewerPreferences(PdfWriter.HideMenubar | PdfWriter.HideToolbar); doc.Close(); doc = null; } catch (Exception e) { throw e; } finally { Dispose(); } return TargetPath; } /// <summary> /// 支持釋放資源可以使用using /// </summary> public void Dispose() { if (wps != null) { wps.Quit(); //釋放掉wps對象 wps = null; #region 強制關閉所有wps的功能慎用,尤其是帶並發的 //強制關閉所有wps進程,解決文件占用的問題 if (this.IsKillAllWps) { System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("wps"); foreach (System.Diagnostics.Process prtemp in process) { prtemp.Kill(); } } #endregion } } }
3、調用代碼如下
/// <summary> /// 開始轉換Pdf /// </summary> private void StatButton_Click(object sender, EventArgs e) { if (File.Exists(PdfFileTextBox.Text)&& Path.IsPathRooted(PdfFileTextBox.Text)) { Stopwatch sw = new Stopwatch(); sw.Start(); using (ToPdfHelper Help = new ToPdfHelper(PdfFileTextBox.Text,true)) { Help.WordWpsToPdf(); } sw.Stop(); TimeSpan ts2 = sw.Elapsed; TimeLabel.Text = string.Format("轉換使用時間：總共花費{0}ms.", ts2.TotalMilliseconds); } else { MessageBox.Show("文件不存在，檢查文件路徑是否正常，只支持絕對路徑！"); } }
