C＃使用OpenXML附加到DOCX文件

Question

我在C＃中使用OpemXML來構建我的DOCX文件。我的代碼看起來是這樣的：「不支持的FileMode值」

using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(wordFileNamePath, true)) 
{ 
    for (int i = 0; i < length; i++) 
    { 
     using (StreamWriter sw = new StreamWriter(i == 0 ? wordDoc.MainDocumentPart.GetStream(FileMode.Create) : wordDoc.MainDocumentPart.GetStream(FileMode.Append, FileAccess.Write))) 
     { 
      sw.Write(tempDocText.ToString()); 
     } 
     if (i < length - 1) 
     { 
      tempDocText = CreateNewStringBuilder(); 
      InsertPageBreak(wordDoc); 
     } 
    } 
    wordDoc.MainDocumentPart.Document.Save(); 
} 

在第二循環中，當涉及到wordDoc.MainDocumentPart.GetStream(FileMode.Append, FileAccess.Write)我得到一個ArgumentException說

我認爲這是在你的代碼中的問題，您正在使用tempDocText.ToString（）如下圖所示

using (StreamWriter sw = new StreamWriter(i == 0 ? wordDoc.MainDocumentPart.GetStream(FileMode.Create) : wordDoc.MainDocumentPart.GetStream(FileMode.Append, FileAccess.Write))) 
{ 
    sw.Write(tempDocText.ToString()); //<-Used before Initialization 
} 

在for循環初始化並初始化其作爲以後的代碼塊之前

if (i < length - 1) 
{ 
    tempDocText = CreateNewStringBuilder(); //<-Initializing it here. 
    InsertPageBreak(wordDoc); 
} 

除非你提供更多的信息有關tempDocText，其難治幫助。

反正，如果你只是想添加文本到docx文件，那麼下面的代碼可能會有所幫助。我發現它here。

public static void OpenAndAddTextToWordDocument(string filepath, string txt) 
{ 
    // Open a WordprocessingDocument for editing using the filepath. 
    WordprocessingDocument wordprocessingDocument = 
     WordprocessingDocument.Open(filepath, true); 

    // Assign a reference to the existing document body. 
    Body body = wordprocessingDocument.MainDocumentPart.Document.Body; 

    // Add new text. 
    Paragraph para = body.AppendChild(new Paragraph()); 
    Run run = para.AppendChild(new Run()); 
    run.AppendChild(new Text(txt)); 

    // Close the handle explicitly. 
    wordprocessingDocument.Close(); 
}
