xml serialization question

[Linda Chen]

I am using XML serialization to convert my C# structure to
a xml file. The file is in GML format. some element name
has ":" inside. For example, one element name
call "gml:coordinates".

The way I did is define an element name before I difine my
public property:

<XmlElement(elementName:="gml:coordinates")> _
Public Property CoordString() As String
Get
Return m_Coords
End Get
Set(ByVal Value As String)
m_Coords = Value
End Set
End Property

After the xml file was generated, I found that the element
name became "gml_x003A_coordinates" instead
of "gml:coordinates".

How do I solve this problem?

Thanks a lot.

That's not just :, that's a namespace prefix.
<XmlElement(elementName:="gml:coordinates")> _

No, you have to provide XmlSeializationNamespaces collection, where to
bind gml namespace prefix to GML namespace:
C# sample:

public class Sample {
[XmlElement(ElementName="coordinates", Namespace="gml namespace")]
public string Property = "ssss";

public static void Main() {
XmlSerializer ser = new XmlSerializer(typeof(Sample));
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("gml", "gml namespace");
Sample s = new Sample();
ser.Serialize(Console.Out, s, ns);
}
}

And the result is:

<Sample xmlns:gml="gml namespace">
<gml:coordinates>ssss</gml:coordinates>
</Sample>
