Question

我有一个带有“@Address”的docx文档 - 我可以用这个代替：

public static void SearchAndReplace(string document)
{
using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true))
{
    string docText = null;
    using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
    {
        docText = sr.ReadToEnd();
    }

    Regex regexText = new Regex("@Address");
    docText = regexText.Replace(docText, multiLineString);

    using (StreamWriter sw = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
    {
        sw.Write(docText);
    }
}
}

问题是字符串是在一行中返回的。

我做错了什么或者是否有替代方法可以用多行文字替换我的文字？

最简单的方法是使用Break（<w:br/>）Wordprocessing元素替换换行符：

public static void SearchAndReplace(string document)
{
    using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(document, true))
    {
        string docText = null;
        using (StreamReader sr = new StreamReader(wordDoc.MainDocumentPart.GetStream()))
            docText = sr.ReadToEnd();

        Regex regexText = new Regex("@Address");

        string multiLineString = "Sample text.\nSample text.";
        multiLineString = multiLineString.Replace("\r\n", "\n")
                                         .Replace("\n", "<w:br/>");

        docText = regexText.Replace(docText, multiLineString);

        using (StreamWriter sw = new StreamWriter(wordDoc.MainDocumentPart.GetStream(FileMode.Create)))
            sw.Write(docText);
    }
}

另外，请注意还有一些其他特殊字符需要替换为相应的Wordprocessing元素例如，<w:tab/>，<w:noBreakHyphen/>，<w:softHyphen/>和<w:sym w:font="X" w:char="Y"/>。
