使用XmlSerializer的与根元素的数组 [英] Using XmlSerializer with an array in the root element

问题描述

我有类似以下内容的XML文档：

I have an XML document similar to the following:

<scan_details>
    <object name="C:\Users\MyUser\Documents\Target1.doc">
        ...
    </object>
    <object name="C:\Users\MyUser\Documents\Target2.doc">
        ...
    </object>
    ...
</scan_details>

我希望使用的System.Xml.Serialization 属性简化XML序列化。这个问题我已经是我可以不知道如何指定根节点包含数组。

I am hoping to use the System.Xml.Serialization attributes to simplify XML deserialization. The issue I have is I cannot work out how to specify that the root node contains an array.

我曾尝试创建以下类：

[XmlRoot("scan_details")]
public class ScanDetails
{
    [XmlArray("object")]
    public ScanDetail[] Items { get; set; }
}

public class ScanDetail
{
    [XmlAttribute("name")]
    public string Filename { get; set; }
}

然而，当我反序列化XML转换成 ScanDetails 对象产品阵遗迹空。

我如何反序列化的根节点的数组？

How do I deserialize an array in a root node?

推荐答案

您应该使用 [的XmlElement] ，而不是 [XmlArray] 装饰物品属性 - 它已经数组，你只想要设置的元素名称

You should use [XmlElement], and not [XmlArray] to decorate the Items property - it's already an array, and you only want to set the element name.

public class StackOverflow_12924221
{
    [XmlRoot("scan_details")]
    public class ScanDetails
    {
        [XmlElement("object")]
        public ScanDetail[] Items { get; set; }
    }

    public class ScanDetail
    {
        [XmlAttribute("name")]
        public string Filename { get; set; }
    }

    const string XML = @"<scan_details> 
                            <object name=""C:\Users\MyUser\Documents\Target1.doc""> 
                            </object> 
                            <object name=""C:\Users\MyUser\Documents\Target2.doc""> 
                            </object> 
                        </scan_details> ";

    public static void Test()
    {
        XmlSerializer xs = new XmlSerializer(typeof(ScanDetails));
        MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(XML));
        var obj = xs.Deserialize(ms) as ScanDetails;
        foreach (var sd in obj.Items)
        {
            Console.WriteLine(sd.Filename);
        }
    }
}
