Trouble deserialising xml file using DataContractSerializer

It's been awhile since i've used DataContractSerializer and i'm having a little trouble deserializing a xml file.

<?xml version="1.0" encoding="utf-8"?> <SoftwareLicense xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

The error i'm getting is:

{"Error in line 1 position 117. Expecting element 'SoftwareLicense' from namespace 'http://schemas.datacontract.org/2004/07/Solentim.Modules.Licensing.Activation'.. Encountered 'Element' with name 'SoftwareLicense', namespace ''. "}

[DataContract(Name = "SoftwareLicense")]
public class SoftwareLicense : ISoftwareLicense
{
    ...
}

I've tried specifying the namespace which also doesn't work.

var serializer = new DataContractSerializer(typeof(SoftwareLicense));

using (var stream = new FileStream(filename, FileMode.Open, FileAccess.Read))
{
    using (var reader =
                XmlDictionaryReader.CreateTextReader(stream, new XmlDictionaryReaderQuotas()))
    {
        return (SoftwareLicense) serializer.ReadObject(reader);
    }
}

The namespace of the file has recently changed and an interface added to the class. I've resolved all other issues i just can't seem to get around this one.

I prefer to use the DatacontractSerializer as the class now has interface properties and XMLSerializer won't deserialise it

This answer may help you to solve your problem.

If you prefer to use XmlSerializer. Here is the simple implementation below:

private T Deserialize<T>(string path) where T : class
{
    XmlSerializer serializer = new XmlSerializer(typeof(T));
    T result = null;
    using (XmlReader reader = XmlReader.Create(path))
    {
       result = (T)serializer.Deserialize(reader);
    }
    return result;
}
