你需要使用xsd.exe工具，它会被安装到一个类似于Windows SDK的目录中:

C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin

在64位计算机上:

C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\bin

在Windows 10电脑上:

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin

在第一次运行时，您使用XSD .exe并将示例XML转换为XSD文件(XML模式文件):

xsd yourfile.xml

这会给你你的文件。在第二步中，您可以再次使用xsd.exe将其转换为c#类:

xsd yourfile.xsd /c

这应该会给你一个文件yourfile.cs，它将包含一个c#类，你可以使用它来反序列化你得到的XML文件-类似于:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
msg resultingMessage = (msg)serializer.Deserialize(new XmlTextReader("yourfile.xml"));

在大多数情况下都能很好地工作。

更新:XML序列化器将接受任何流作为它的输入-文件或内存流都可以:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(inputString));
msg resultingMessage = (msg)serializer.Deserialize(memStream);

或者使用StringReader:

XmlSerializer serializer = new XmlSerializer(typeof(msg));
StringReader rdr = new StringReader(inputString);
msg resultingMessage = (msg)serializer.Deserialize(rdr);

public string Serialize<T>(T settings)
{
    XmlSerializer serializer = new XmlSerializer(typeof(T));
    StringWriter outStream = new StringWriter();
    serializer.Serialize(outStream, settings);
    return outStream.ToString();
}

除了这里的其他答案之外，您还可以自然地使用XmlDocument类(用于类似XML dom的读取)或XmlReader(仅向前的快速读取器)来“手动”执行此操作。

另一种高级xsd到c#类生成工具:xsd2code.com。这个工具非常方便和强大。它比Visual Studio中的xsd.exe工具有更多的自定义。xsd2code++可以定制为使用列表或数组，并支持包含大量Import语句的大型模式。

注意一些特征，

Generates business objects from XSD Schema or XML file to flexible C# or Visual Basic code. Support Framework 2.0 to 4.x Support strong typed collection (List, ObservableCollection, MyCustomCollection). Support automatic properties. Generate XML read and write methods (serialization/deserialization). Databinding support (WPF, Xamarin). WCF (DataMember attribute). XML Encoding support (UTF-8/32, ASCII, Unicode, Custom). Camel case / Pascal Case support. restriction support ([StringLengthAttribute=true/false], [RegularExpressionAttribute=true/false], [RangeAttribute=true/false]). Support large and complex XSD file. Support of DotNet Core & standard

创建一个DTO作为CustomObject

使用下面的方法使用JAXB将XML字符串转换为DTO

private static CustomObject getCustomObject(final String ruleStr) {
    CustomObject customObject = null;
    try {
        JAXBContext jaxbContext = JAXBContext.newInstance(CustomObject.class);
        final StringReader reader = new StringReader(ruleStr);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        customObject = (CustomObject) jaxbUnmarshaller.unmarshal(reader);
    } catch (JAXBException e) {
        LOGGER.info("getCustomObject parse error: ", e);
    }
    return customObject;
}

简化达米安的回答，

public static T ParseXml<T>(this string value) where T : class
{
    var xmlSerializer = new XmlSerializer(typeof(T));
    using (var textReader = new StringReader(value))
    {
        return (T) xmlSerializer.Deserialize(textReader);
    }
}
