C# XML 编写器 - 使用哪些类型/对象？

发布于 2025-01-11 23:54:28 字数 809 浏览 0 评论 0原文

简介：各位编码员大家好；我创建了一个项目来创建 XML 文件，以便使用某些设置自动创建文件。

问题：我的知识不足以重现这一点。我找不到关于两个问题的正确信息；

A. 如何在元素内部创建元素（使用第二个 writestartelement 关闭第一个元素）；

B. 第 3 行有一个我不认识的元素。谁能告诉我应该在网上寻找哪种类型？

<userEnvironmentSettings>
    <conditions>
        <ref n="Printer - PR123456.xml" />
    </conditions>
</userEnvironmentSettings>

当前代码（将保持最新）

                writer.WriteStartElement("userEnvironmentSettings");
                writer.WriteStartElement("conditions");
                writer.WriteAttributeString("ref n", "Printer - " + printerName + ".xml\"");
                writer.WriteEndElement();
                writer.WriteEndElement();
                writer.Flush();

结果：无法在 Attributestring 内设置空格的 $exception。

Intro:
Hi fellow coders; I created a project to create XML files to automate filecreation with certain settings.

Issue: my knowledge isn't sufficient to recreate this. I can't find the right information on two questions;

A. How to create an element inside an element (using a second writestartelement closes the first one);

B. On line 3 there's an element which I do not recognise. Can anybody tell me which type I should be looking for on the net?

<userEnvironmentSettings>
    <conditions>
        <ref n="Printer - PR123456.xml" />
    </conditions>
</userEnvironmentSettings>

Current code (Will keep this up to date)

                writer.WriteStartElement("userEnvironmentSettings");
                writer.WriteStartElement("conditions");
                writer.WriteAttributeString("ref n", "Printer - " + printerName + ".xml\"");
                writer.WriteEndElement();
                writer.WriteEndElement();
                writer.Flush();

Result: $exception as per a whitespace cannot be set inside Attributestring.

您需要一个名为 ref 的元素，以及一个名为 n 的属性。您尝试做的是在 conditions 元素中创建一个名为 ref n 的属性，这是不允许的（因为它包含空格）并且不是您想要的。所以这可行：

writer.WriteStartElement("userEnvironmentSettings");
writer.WriteStartElement("conditions");
writer.WriteStartElement("ref");
writer.WriteAttributeString("n", "Printer - PR123456.xml");
writer.WriteEndElement();
writer.WriteEndElement();
writer.WriteEndElement();

但是，除非您有充分的理由，否则我强烈建议您不要直接使用XmlWriter。您可以使用更简单、更高级别的 API。例如：

var doc = new XDocument(
    new XElement("userEnvironmentSettings",
        new XElement("conditions",
            new XElement("ref",
                new XAttribute("n", "Printer - PR123456.xml")
            ))));
doc.Save(fileName);

You need an element called ref with an attribute called n. What you've tried to do is create an attribute called ref n within the conditions element, which is not allowed (as it contains whitespace) and is not what you want. So this would work:

writer.WriteStartElement("userEnvironmentSettings");
writer.WriteStartElement("conditions");
writer.WriteStartElement("ref");
writer.WriteAttributeString("n", "Printer - PR123456.xml");
writer.WriteEndElement();
writer.WriteEndElement();
writer.WriteEndElement();

However, unless you have good reason I'd strongly suggest you don't use XmlWriter directly. There are much easier, higher-level APIs you can use. For example:

var doc = new XDocument(
    new XElement("userEnvironmentSettings",
        new XElement("conditions",
            new XElement("ref",
                new XAttribute("n", "Printer - PR123456.xml")
            ))));
doc.Save(fileName);
