將word文檔轉換爲pdf

Question

我有一個RadGridView應該導出爲doc，pdf，csv和xls格式。導出到doc，csv和xls可以正常工作......但將其導出爲pdf格式時出錯。在導出爲PDF的作品，但列，我躲還表示...

所以我只是想通過導出RadGridView到PDF的：其導出到Word然後將其轉換爲PDF格式編程...

通過方式，這是我的代碼導出到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); 
     } 
    } 
}

通過OLE自動化用字（注：字COM不重入 - 確保不從不同的線程同時調用此）：

/// <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

使用的DevExpress（下面的代碼只適用於RTF格式 - 不一定適用於所有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); 
    }
