使用 C# 将 XML 文件写入特定的 XML 结构

本文关键字：XML 结构 文件 使用 | 更新日期: 2023-09-27 18:35:46

通常

的方法是，我编写XML文件的代码是，

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Indent = true;
    XmlWriter writer = XmlWriter.Create("Products.xml", settings);
    writer.WriteStartDocument();
    writer.WriteComment("This file is generated by the program.");
    writer.WriteStartElement("Product");
    writer.WriteAttributeString("ID", "001");
    writer.WriteAttributeString("Name", "Keyboard");
    writer.WriteElementString("Price", "10.00");
    writer.WriteStartElement("OtherDetails");
    writer.WriteElementString("BrandName", "X Keyboard");
    writer.WriteElementString("Manufacturer", "X Company");
    writer.WriteEndElement();
    writer.WriteEndDocument();
    writer.Flush();
    writer.Close();

但是上面的代码给了我一个不同的XML结构，如果我需要输出，如何编码，如下所示的结构，

<Books>
<Book ISBN="0553212419">
<title>Sherlock Holmes</title>
<author>Sir Arthur Conan Doyle</author>
</Book>
<Book ISBN="0743273567">
<title>The Great Gatsby</title>
<author>F. Scott Fitzgerald</author>
</Book>
<Book ISBN="0684826976">
<title>Undaunted Courage</title>
<author>Stephen E. Ambrose</author>
</Book>
<Book ISBN="0743203178">
<title>Nothing Like It In the World</title>
<author>Stephen E. Ambrose</author>
</Book>
</Books>

谢谢

使用 C# 将 XML 文件写入特定的 XML 结构

正如评论的那样，只需修改您已经必须编写的代码即可编写正确的元素。

XmlWriter writer = XmlWriter.Create(@"Products.xml", settings);
writer.WriteStartDocument();
writer.WriteComment("This file is generated by the program.");
writer.WriteStartElement("Books");
writer.WriteStartElement("Book");
writer.WriteAttributeString("ISBN", "0553212419");
writer.WriteElementString("Title", "Sherlock Holmes");
writer.WriteElementString("Author", "Sir Arthur Conan Doyle");
writer.WriteEndElement();
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Flush();
writer.Close();

清洗，冲洗，重复。我建议编写一种方法来添加每本书。

编辑 - 写书的方法

void WriteBookData(XmlWriter writer, string isbn, string title, string author)
{
    writer.WriteStartElement("Book");
    writer.WriteAttributeString("ISBN", isbn);
    writer.WriteElementString("Title", title);
    writer.WriteElementString("Author", author);
    writer.WriteEndElement();
}
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
using (XmlWriter writer = XmlWriter.Create(@"Products.xml", settings))
{
    writer.WriteStartDocument();
    writer.WriteComment("This file is generated by the program.");
    writer.WriteStartElement("Books");
    WriteBookData(writer, "0553212419", "Sherlock Holmes", "Sir Arthur Conan Doyle");
    writer.WriteEndElement();
    writer.WriteEndDocument();
    writer.Flush();
}

你为什么不使用Linq to XML。它非常简单，非常容易理解

   string filename = string.Empty;
 XElement res= new XElement ("Books",new XElement ("Book",new XAttribute   ("ISBN","="+055321212),
            new XElement ("Title","Sherlock Homes"),
            new XElement ("author","Sir Arthur Conan")
            )
            );

        res.Save(filename);

您可以使用 foreach look 在上述语句中存储硬编码值
