XML error during deserialize

I have problem when I'm trying to deserialize an XML to object. My XML look like:

<?xml version="1.0" encoding="utf-16"?>
<Products
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <AllProducts>
        <Product>
            <ID>8</ID>
            <GID>51280</GID>
            <Kod>RNIKAKC1.6</Kod>
            <Name>SB-800</Name>
            <Ean>0018208048014</Ean>
            <CommodityGroup>
                <ID>86</ID>
                <Name>AKCESORIA FOTO</Name>
                <Path>
                    <Category>
                        <ID>60798</ID>
                        <Name>ARCHIWALNE</Name>
                    </Category>
                </Path>
            </CommodityGroup>
         </Product>
....
Next products
...

My method code:

var MemoryStream = APIAccess.DownloadFileToStream("example.xml", "exampleContainer");
            using (MemoryStream)
            {
                MemoryStream.Position = 0;
                using (StreamReader StreamReader = new StreamReader(MemoryStream))
                {
                    XmlSerializer serializer = new XmlSerializer(typeof(CommodityGroup));
                    var products = serializer.Deserialize(StreamReader);
                }
            }

Method DownloadFileToStream is working good, because it is useful in other classes.

I'm geting error:

InvalidOperationException: Products xmlns='' was not expected.

I want to create object of a Node CommodityGroup. I've created class selecting this node, coping it and pasting in the new class like Paste Special -> XML

Attributes of this class looks like:

[Serializable()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[XmlTypeAttribute(AnonymousType = true)]
[XmlRootAttribute(Namespace = "CommodityGroup", IsNullable = false)]

I don't know to fix it. When I'm adding into XML Serializer param new XmlRootAttribute("Products"), I'm getting "0" values.

Do you have any suggestions?

If you want to deserialize only part of an xml document, you should skip unnecessary nodes.

Do it using XmlReader.

using (StreamReader StreamReader = new StreamReader(MemoryStream))
using (var xmlReader = XmlReader.Create(StreamReader))
{
    xmlReader.ReadToFollowing("CommodityGroup");
    XmlSerializer serializer = new XmlSerializer(typeof(CommodityGroup));
    var commodityGroup = (CommodityGroup)serializer.Deserialize(xmlReader);
}
