将word文档转换为pdf

Question

我有一个RadGridView应该导出为doc，pdf，csv和xls格式。导出到doc，csv和xls可以正常工作......但将其导出为pdf格式时出错。在导出为PDF的作品，但列，我躲还表示...

所以我只是想通过导出RadGridView到PDF的：其导出到Word然后将其转换为PDF格式编程...

通过方式，这是我的代码导出到word。

 
//export to doc 
private void Export_Doc(object sender, System.Windows.RoutedEventArgs e) 
{ 
    ExportDialog("doc", "Word", ExportFormat.Html); 
} 
private void ExportDialog(string extension, string selectedItem, ExportFormat format) 
{ 
    SaveFileDialog dialog = new SaveFileDialog(); 
    dialog.DefaultExt = extension; 
    dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem); 
    dialog.FilterIndex = 1; 
    if (dialog.ShowDialog() == true) 
    { 
     using (Stream stream = dialog.OpenFile()) 
     { 
      GridViewExportOptions exportOptions = new GridViewExportOptions(); 
      exportOptions.Format = format; 
      exportOptions.ShowColumnFooters = true; 
      exportOptions.ShowColumnHeaders = true; 
      exportOptions.ShowGroupFooters = true; 

      RadGridView1.Export(stream, exportOptions); 
     } 
    } 
}

通过OLE自动化用字（注：字COM不重入 - 确保不从不同的线程同时调用此）：

/// <summary> 
    /// Interacts directly with Word via COM to convert a document to PDF 
    /// Must have the Microsoft enhancement installed to support Save As PDF 
    /// in the word file menu 
    /// "2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS" - SaveAsPDFandXPS.exe 
    /// </summary> 
    private void ExportToPDFUsingWord(object sourceDoc, string destPDF) 
    { 
     object m = System.Reflection.Missing.Value; 
     object readOnly = true; 
     object myFalse = false; 
     object isVisible = false; 
     object matchCase = false; 
     object matchWholeWord = true; 
     object saveChangesWhenQuitting = false; 

     //Debug("Connecting to word"); 
     _Application oWordApp = new Application(); 
     _Document oWordDoc = null; 
     Documents oWordDocs = null; 

     try 
     { 
      // load the source file 
      //Debug("Opening " + sourceDoc); 
      oWordDocs = oWordApp.Documents; 
      oWordDoc = oWordDocs.Open(ref sourceDoc, ref m, ref readOnly, ref m, ref m, ref m, ref m, ref m, ref m, ref m, ref m, ref isVisible, ref m, ref m, ref m, ref m); 

      if (oWordDoc != null) 
      {

        oWordDoc.ExportAsFixedFormat(destPDF,

      GC.Collect(); // forces the garbage collector to run and might release any references that the RCW still has 
      GC.WaitForPendingFinalizers();

     } 
    }

使用的DevExpress（下面的代码只适用于RTF格式 - 不一定适用于所有Word的功能）：

private void ExportToPDFUsingDevExpress(string sourceDoc, string destPDF) 
    { 
     DevExpress.XtraPrinting.PrintingSystem printingSystem1 = new DevExpress.XtraPrinting.PrintingSystem(); 
     DevExpress.XtraRichEdit.RichEditControl richEditControl1 = new DevExpress.XtraRichEdit.RichEditControl(); 
     richEditControl1.LoadDocument(sourceDoc); 
     DevExpress.XtraPrinting.PrintableComponentLink link = new DevExpress.XtraPrinting.PrintableComponentLink(printingSystem1); 
     link.Component = richEditControl1; 
     link.CreateDocument(); 
     link.PrintingSystem.ExportToPdf(destPDF); 
    }
