我怎么能替换文件

Question

与合并字段中的所有文本我有两个“DEMO”字

，我想替换成MERGEFIELD

只是一个“DEMO”用我的代码改变...

我怎样才能取代文本与字段？

感谢

 Application app = new Application(); 
     Document word = new Document(); 

     word = app.Documents.Add(ref path, ref missing, ref missing, ref missing); 

     object objType = WdFieldType.wdFieldMergeField; 

     object hashVal = null; 
     Hashtable hash = new Hashtable(); 

     hash.Add("DEMO", "mergefield11111"); 


     foreach (object s in hash.Keys) 
     { 

      Range rng = app.ActiveDocument.Content; 
      Find findObject = app.Selection.Find; 

      object ff = s; 
      hashVal = hash[s];  

      findObject.Text = ff.ToString(); 
      findObject.ClearFormatting(); 
      if (rng.Find.Execute(ref ff, 
      ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, 
      ref missing, ref missing, ref missing, WdReplace.wdReplaceOne, ref missing, ref missing, 
      ref missing, ref missing)) 
      { 
       Field field = app.Selection.Fields.Add(app.Selection.Range, ref objType, ref hashVal, ref missing); 
      } 
     } 
     app.Documents.Open("test1.docx"); 

Answer 1

你只是在做一个Find操作。请尝试while (rng.Find.Execute(...)) { ... }

您可以使用Open XML SDK 2.5。您可以将Office文件读取为Big XML文件，然后您可以更改所需内容。

1. 您必须阅读的Word文件的MemoryStream

public byte[] DocumentGenerator(String templatePath) 
    { 
     byte[] buffer; 
     using (MemoryStream stream = new MemoryStream()) 
     { 
      buffer = System.IO.File.ReadAllBytes(templatePath); 
      stream.Write(buffer, 0, buffer.Length); 
      using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(stream, true)) 
      { 
       //Get list bookmarks 
       var listBookMarks = wordDocument.MainDocumentPart.Document.Descendants<BookmarkStart>().ToList(); 
       //Get list Merge Fields 
       var listMergeFields = wordDocument.MainDocumentPart.Document.Descendants<FieldCode>().ToList(); 
       //Do some code 
       wordDocument.Close(); 
      } 
      buffer = stream.ToArray(); 
     } 

     return buffer; 
    } 

然后，您可以更改文本，添加段落，添加表或其他。你可以用你的Office文件做所有事情。 （Word，Excel ...） 这是我的例子。我试着在我的书签字段中添加项目符号列表：

  if (bookmark != null) 
     { 
      var parent = bookmark.Parent; // bookmark's parent element 
      var childEllement = parent.Elements<Run>().Last(); 
      var lastChild = childEllement.LastChild; 
      childEllement.RemoveChild(lastChild); 


      foreach (var itemChild in groupList) 
      { 

       Paragraph paragraph1 = new Paragraph(); 
       ParagraphProperties paragraphProperties = new ParagraphProperties(); 
       ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "ListParagraph" }; 
       Tabs tabs = new Tabs(); 
       TabStop tabStop1 = new TabStop() { Val = TabStopValues.Left, Position = 284 }; 

       tabs.Append(tabStop1); 
       SpacingBetweenLines spacingBetweenLines1 = new SpacingBetweenLines() { After = "120", Line = "360", LineRule = LineSpacingRuleValues.Auto }; 
       Indentation indentation1 = new Indentation() { Left = "0", FirstLine = "0" }; 
       Justification justification = new Justification() { Val = JustificationValues.Both }; 

       ParagraphMarkRunProperties paragraphMarkRunProperties1 = new ParagraphMarkRunProperties(); 

       paragraphProperties.Append(paragraphStyleId1); 
       paragraphProperties.Append(tabs); 
       paragraphProperties.Append(spacingBetweenLines1); 
       paragraphProperties.Append(indentation1); 
       paragraphProperties.Append(justification); 
       paragraphProperties.Append(paragraphMarkRunProperties1); 
       Run run1 = new Run(); 
       RunProperties runProperties1 = new RunProperties(); 

       Bold bold2 = new Bold(); 
       FontSizeComplexScript fontSizeComplexScript2 = new FontSizeComplexScript() { Val = "24" }; 

       runProperties1.Append(bold2); 
       runProperties1.Append(fontSizeComplexScript2); 
       Text text1 = new Text(); 
       text1.Text = "- " + itemChild + ";"; 
       run1.Append(runProperties1); 
       run1.Append(text1); 
       paragraph1.Append(paragraphProperties); 
       paragraph1.Append(run1); 
       parent.InsertAfterSelf(paragraph1); 
      } 
     }
