deserializing and XML file [.csdl file EntityFramework]

[VRSki]

I am trying to deserialize a .csdl file, generated by EdmGen.exe (part of MS
Entity Framework). The file itself is an xml file, even though it has a .csdl
extension. But unfortunately, the second line contains an element that
doesn't seem to be supported by XML serializer:

------- XML start --------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<Schema Namespace="SomeProject" Alias="Self"
xmlns="http://schemas.microsoft.com/ado/2006/04/edm">
<Element1>data</Element1>
</Schema>
------- XML end --------------------------------------------------------

Here is the code I use to deserialize this fileL:

// read in the file into the stream
System.IO.Stream oCsdlXml = ....

// create the serializer -- Schema class contains Element1 member
XmlSerializer oSerializer = new XmlSerializer(typeof(Schema));

// this line below throws exception:
Schema oSchema = oSerializer.Deserialize(oCsdlXml) as Schema;

Exception: "There is an error in XML document (2, 2)"
Internal Exception: "<Schema
xmlns='http://schemas.microsoft.com/ado/2006/04/edm'> was not expected."

If I take out this part from the xml file -- it all works and my Element1 is
properly deserialized:

xmlns="http://schemas.microsoft.com/ado/2006/04/edm"


Is that a truly invalid XML construct? Is there any way to deserialize this
using attribute overrides?

Thank you for your help,

Can you try the same thing with the DataContractSerializer?

Tried that. Here is the new error message (no inner exception).

Error in line 1 position 93. Expecting element 'Schema' from namespace
'http://schemas.datacontract.org/2004/07/XmlSchemaDeserializerTest'..
Encountered 'Element' with name 'Schema', namespace
'http://schemas.microsoft.com/ado/2006/04/edm'.

Thanks,

The data type that you are trying to serialize into -- it has a
different namespace declared for the 'Schema' element than what is
declared in your XML itself.

Could you please help me out here? I am not sure what you mean by "it has a
different namespace declared for the 'Schema'"..

The element I am trying to serialize the stream to IS Schema:

XmlSerializer oSerializer = new XmlSerializer(typeof(Schema));

And Schema is a pretty straight-forward class:

namespace SomeNamespace
{
[Serializable]
public class Schema
{
public Schema() {}
public string Element1() {get;set;}
}
}

What namespace should I change in Schema class to make it work? Are you
saying namespace SomeNamespace should be renamed?

Thanks again for your help.
