您好我有以下反序列化代码

        public static T DeserializeXML<T>(String xml) where T : class
        {
            T newObject = null;
            XmlSerializer s = new XmlSerializer(typeof(T));
            using (StringReader sw = new StringReader(xml))
            {
                newObject = (T)s.Deserialize(sw);
            }
            return newObject;
        }

我尝试反序列化的消息

<Data>
<ItemIn date="2012-08-09T10:25:54.06+01:00" itemId="000007721" Id="1">   <Extensions><Info Id="parts" order="issue"/></Extensions></ItemIn>
</Data>

但我只是从来没有被Extensions部分地渴望回到我总是去null那里的原始班级。其余的课程还可以。

有什么建议要检查什么？

对于扩展......看起来你已经编辑了代码；有

private Extensions extensions;

...

/// <remarks/>
public ItemTransferInExtensions Extensions {
    get {
        return this.extensions;
    }
    set {
        this.extensions = value;
    }
}

坦率地说，这甚至不应该编译；我们没有课ItemTransferInExtensions。

此外，Info不会工作：

/// <remarks/>
public RecipeInfo RecipeInfo {...blah...}

不匹配<Info ..../>。所以要么更正xsd并重新生成cs，要么更正xml；但此刻他们不匹配。

RecipeInfo将属性重命名为Info（您也可以只添加一个属性）并修复 Extensions / ItemTransferInExtensions （和缺失的}），并添加一个根类以匹配 xml：

public class Data
{
    public ItemTransferIn ItemIn { get; set; }
}

...一切正常：

static void Main()
{
    string msg = @"<Data>
<ItemIn date=""2012-08-09T10:25:54.06+01:00"" itemId=""000007721"" Id=""1"">   <Extensions><Info Id=""parts"" order=""issue""/></Extensions></ItemIn>
</Data>";
    var obj = DeserializeXML<Data>(msg);

    Console.WriteLine(obj.ItemIn.Extensions.Info.order); // issue
}

不过，坦率地说，手动操作更容易：

public class Data
{
    public ItemTransferIn ItemIn { get; set; }
}
public class ItemTransferIn
{
    [XmlAttribute("date")]
    public DateTime Date { get; set; }

    [XmlAttribute("itemId")]
    public string Itemid { get; set; }

    [XmlAttribute]
    public int Id { get; set; }

    public Extensions Extensions { get; set; }
}
public class Extensions
{
    public ExtensionsInfo Info { get; set; }
}
public class ExtensionsInfo
{
    public int Id { get; set; }
    [XmlAttribute("order")]
    public string Order { get; set; }
}
