为什么我的SOAP XML响应不会在C＃中反序列化？

Question

My soap service call is returning the following response:

<AssetList xmlns="http://schemas.datacontract.org/2004/07/XOSDigital.Assets" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <Facets xmlns:a="http://schemas.datacontract.org/2004/07/XOSDigital.Business_Classes.Search"/>
  <Results/>
  <err i:nil="true"/>
  <offset>0</offset>
  <total>0</total>
</AssetList>

When I attempt to serialize this via:

        AssetList assets;
        var serializer = new XmlSerializer(typeof(AssetList));
        assets = (AssetList)serializer.Deserialize(new MemoryStream(Encoding.UTF8.GetBytes(response.Content)));

I get the following exception:

<AssetList xmlns='http://schemas.datacontract.org/2004/07/XOSDigital.Assets'> was not expected.

The AssetList object I am trying to deserialize to was automatically generated by updating my service reference against the same exact service I am calling with my GET request.

Why is this failing?

The AssetList class is generated as:

Answer 1

I think the problem is related with namespaces.

Can you try this?

var serializer = new XmlSerializer(typeof(AssetList),"http://schemas.datacontract.org/2004/07/XOSDigital.Assets");

Answer 2

Try to add this as the first line in your xml:

<?xml version="1.0"?>

Also, add XmlRoot attribute with namespace to your AssetList class:

[XmlRoot("AssetList", Namespace = "http://schemas.datacontract.org/2004/07/XOSDigital.Assets")]
