Question

我想改变我的代码：

string path = @"c:\Directory\test.xml";
XmlSerializer s = new XmlSerializer(typeof(Car));

TextReader r = new StreamReader(path);

Car car = (Car)s.Deserialize(r);
r.Close();

代码将XML转换为字符串，然后将字符串转换为对象Car。

这可能吗？

Answer 1

public static string XmlSerializeToString(this object objectInstance)
{
    var serializer = new XmlSerializer(objectInstance.GetType());
    var sb = new StringBuilder();

    using (TextWriter writer = new StringWriter(sb))
    {
        serializer.Serialize(writer, objectInstance);
    }

    return sb.ToString();
}

public static T XmlDeserializeFromString<T>(this string objectData)
{
    return (T)XmlDeserializeFromString(objectData, typeof(T));
}

public static object XmlDeserializeFromString(this string objectData, Type type)
{
    var serializer = new XmlSerializer(type);
    object result;

    using (TextReader reader = new StringReader(objectData))
    {
        result = serializer.Deserialize(reader);
    }

    return result;
}

使用它：

//Make XML
var settings = new ObjectCustomerSettings();
var xmlString = settings.XmlSerializeToString();

//Make Object
var settings = xmlString.XmlDeserializeFromString<ObjectCustomerSettings>();

Answer 2

如果您将XML存储在字符串变量中，则可以使用StringReader：

var xml = @"<car/>";
var serializer = new XmlSerializer(typeof(Car));
using (var reader = new StringReader(xml))
{
    var car = (Car)serializer.Deserialize(reader);
}

Answer 3

1-liner，将XML字符串text和YourType作为预期的对象类型。与其他答案差别不大，只是压缩到1行：

var result =  (YourType)new XmlSerializer(typeof(YourType)).Deserialize(new StringReader(text));

Answer 4

static T DeserializeXml<T>(string sourceXML) where T : class
{
    var serializer = new XmlSerializer(typeof(T));
    T result = null;

    using (TextReader reader = new StringReader(sourceXML))
    {
        result = (T) serializer.Deserialize(reader);
    }

    return result;
}

Answer 5

无耻地复制 Generic deserialization of an xml string

    public static T DeserializeFromXmlString<T>(string xmlString)
    {
        var serializer = new XmlSerializer(typeof(T));
        using (TextReader reader = new StringReader(xmlString))
        {
            return (T) serializer.Deserialize(reader);
        }
    }

从字符串反序列化而不是TextReader
