使用OpenXML将C#追加到DOCX文件
我在C#中使用OpemXML来构建我的DOCX文件。我的代码如下所示:使用OpenXML将C#追加到DOCX文件,c#,.net,stream,openxml,C#,.net,Stream,Openxml,我在C#中使用OpemXML来构建我的DOCX文件。我的代码如下所示: using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(wordFileNamePath, true)) { for (int i = 0; i < length; i++) { using (StreamWriter sw = new StreamWriter(i == 0 ? wordDoc.MainDo
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();
}
使用(WordprocessingDocument wordDoc=WordprocessingDocument.Open(wordFileNamePath,true))
{
for(int i=0;i
在第二个循环中,当涉及到
wordDoc.MainDocumentPart.GetStream(FileMode.Append,FileAccess.Write)
时,我得到一个ArgumentException,它说“FileMode值不受支持。”我认为您的代码中有问题,您使用的是tempDocText.ToString()在for循环中初始化之前,如下所示
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
}
代码比我发布的要大,但是完整的代码不会有任何区别。正如您所说,应该在循环之前初始化tempDocText。“长度”也应该初始化。我的目标不是附加一个简单的文本,我需要附加一个xml(经过一些修改)。这个xml是从另一个DOCX文件中获取的,也许这会对您有所帮助。您提供的答案中的那个家伙没有附加内容,他做的和我在I=0时做的一样。然后,他关闭wordProcessingDocument并将其流保存为一个新的docx文件
if (i < length - 1)
{
tempDocText = CreateNewStringBuilder(); //<-Initializing it here.
InsertPageBreak(wordDoc);
}
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();
}
