将XMLDocument读入对象

时间：2011-05-15 14:58:58

标签： c# xml

这应该很简单，但我很难理解如何使用XMLReader或Linq来做到这一点。

这是我周末工作的宠物项目，以提高我的技能 - 理想情况下，这应该将所有嵌套对象作为头等对象，但我对如何解释这个的想法持开放态度

编辑：我已经尝试过XMLReader，但是我的代码错误超过了30行并且看起来很糟糕 - 在C＃中如何将XML转换为对象？

我可以使用反序列化器将其反序列化为对象吗？如果是这样，我是否可以手工构建所有对象？

我想我以前不明白你的问题 因此，您需要创建一个XML序列化的类，并且XML将具有您显示的布局？

如果是这样，您需要：

  1. 创建XSD架构。 xsd.exe可以从xml推断模式。您可能需要手动更正推断的架构。推断架构：

    xsd.exe 1.xml

    这将生成1.xsd文件。

  2. 使用xsd.exe创建C＃类。

    xsd.exe 1.xsd /classes /language:cs

    这将生成1.cs文件。

  3. 将1.cs文件添加到项目中，并在代码中使用自动生成的类。使用XmlSeralizer序列化/反序列化XML。

    4. 您可以在.NET SDK中找到xsd.exe（例如C：\ Program Files（x86）\ Microsoft SDKs \ Windows \ v7.0A \ Bin \ x64）。

答案 1 :(得分：0)

一种方法是使用.NET框架工具附带的XML Schema Definition Tool (Xsd.exe)。如果在Visual Studio中加载XML，则可以使用“创建架构”选项（XML＆gt;创建架构），然后使用xsd.exe使用/c开关生成类。

xsd.exe /c myschema.xsd
  

“生成与之对应的类   指定的架构。读取XML数据   进入对象，使用   System.Xml.Serialization.XmlSerializer.Deserializer   方法“。

希望能给你一些想法吗？

如果您想将XML文本读入XML对象，我建议使用LINQ-to-XML 您可以使用XDocument.Parse或XDocument.Load方法 例如：

    var xmlText = @"

            <module>
                <moduleCode>ECSC401</moduleCode>

                <credits>15</credits>
                <semester>1</semester>
                <assessmentDetails>
                    <assessment>
                        <assessmentName>Test1</assessmentName>
                        <assessmentType>Coursework</assessmentType>
                        <assessmentWeighting>30</assessmentWeighting>
                        <assessmentDueDate></assessmentDueDate>
                    </assessment>
                </assessmentDetails>
            </module>
        </level4>
        ";
    var xdocument = XDocument.Parse(xmlText);

答案 3 :(得分：0)

一种方法是将字符串与xml数据一起使用，另一种方法是“序列化程序”，XML序列化程序对象用于读取XML文档。

此函数返回对象，该对象是对象的初始化实例

public object LoadFromXmlDocument(string xmlDocument, XmlSerializer serializer)
{
    if (StringUtil.IsEmpty(xmlDocument))
       throw new ArgumentNullException("xmlDocument");
    else if (serializer == null)
       throw new ArgumentNullException("serializer");

//Initializing instance for textreader
TextReader reader = new StringReader(xmlDocument);

//Serializing a textreader content
object obj = serializer.Deserialize(reader);
reader.Close();
reader = null;
return obj;
}
