编写具有属性的 xmlns 元素 [英] Write xmlns element with attributes

问题描述

我正在使用 XmlWriter 生成 XML 文件.我正在尝试复制一个旧的 XML 文件，我想创建一个看起来像的条目；

I'm using XmlWriter to generate an XML file. I am trying to replicate an old XML file and I want to create an entry that will look like;

<Return xmlns="http://address/here" appName="Data Return - Collection Tool" appVer="1.1.0">

我的代码如下:

        writer.WriteStartElement("Return", "http://address/here")
        writer.WriteAttributeString("appName", "Data Return - Collection Tool")
        writer.WriteAttributeString("appVer", "1.1.0")

这是以错误的顺序生成属性，即.

This is generating the attributes in the wrong order ie.

<Return appName="Data Return - Collection Tool" appVer="1.1.0" xmlns="http://address/here">

我怎样才能让这些按照我想要的顺序出现.请提供任何帮助.

How can i get these to appear in the order i want. Any help please.

推荐答案

XmlWriter 允许您在需要时编写 xmlns 属性，前提是该值与 WriteStartElement 中指定的值相同:

XmlWriter allow you to write the xmlns attribute when you want if the value is the same than the one specified in WriteStartElement :

void Main()
{
    StringWriter stringWriter = new StringWriter();
    using(XmlWriter writer = XmlWriter.Create(stringWriter))
    {
        writer.WriteStartDocument();
        writer.WriteStartElement("Return", "http://address/here");
        writer.WriteAttributeString("xmlns", "http://address/here");
        writer.WriteAttributeString("appName", "Data Return - Collection Tool");
        writer.WriteAttributeString("appVer", "1.1.0");
        writer.WriteEndElement();
        writer.WriteEndDocument();
    }

    Console.WriteLine(stringWriter.ToString());
}

输出:

<Return xmlns="http://address/here" appName="Data Return - Collection Tool" appVer="1.1.0" />
