[英]C# Append to DOCX file using OpenXML
I am using OpemXML in C# in order to build my DOCX file. 我在C#中使用OpemXML来构建DOCX文件。 My code looks like this:
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.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();
}
On the second loop, when it comes to wordDoc.MainDocumentPart.GetStream(FileMode.Append, FileAccess.Write)
I'm getting an ArgumentException saying "FileMode value is not supported." 在第二个循环中,当涉及到
wordDoc.MainDocumentPart.GetStream(FileMode.Append, FileAccess.Write)
我收到一个ArgumentException,说“不支持FileMode值”。
I think there is a problem in your code, you are using tempDocText.ToString() before initializing it in the for loop as shown below 我认为您的代码中有问题,您正在使用tempDocText.ToString(),然后在for循环中对其进行初始化,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
}
and Initializing it as in the later code block 并按照后面的代码块中的方法进行初始化
if (i < length - 1)
{
tempDocText = CreateNewStringBuilder(); //<-Initializing it here.
InsertPageBreak(wordDoc);
}
Unless you provide more information about tempDocText , its dificult to help. 除非您提供有关tempDocText的更多信息, 否则它会有所帮助。
Anyways, if you just want to add text to a docx file then the following code may help. 无论如何,如果您只想向docx文件中添加文本,则以下代码可能会有所帮助。 I found it here .
我在这里找到的。
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();
}
