Hi all
How can I create a new/empty ILayerDefinition object?
I used to (MaestroAPI 2) create a new ILayerDefinition by using xml and
deserialize and then save the resource (see code below), but in MaestroAPI 4
i get the error: System.NotSupportedException - Cannot serialize interface
OSGeo.MapGuide.ObjectModels.LayerDefinition.ILayerDefinition.
I cannot do "new ILayerDefinition()" ofcourse but how could I create a new
ILayerDefinition object? Is the xml wrong or do I need to do it some other
way (IResourceSerrvice.CreateLayerDefinition)?
--- code ---
string layerDefinition =
"<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
"<LayerDefinition
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\";
xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\";
xsi:noNamespaceSchemaLocation=\"LayerDefinition-1.1.0.xsd\"
version=\"1.1.0\">" +
" <VectorLayerDefinition>" +
" <ResourceId />" +
" <FeatureName />" +
" <FeatureNameType>FeatureClass</FeatureNameType>" +
" <Geometry />" +
" <VectorScaleRange />" +
" </VectorLayerDefinition>" +
"</LayerDefinition>";
ILayerDefinition ldef;
using (System.IO.MemoryStream ms = new
System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes(layerDefinition)))
ldef = con.ResourceService.DeserializeObject<ILayerDefinition>(ms);
string resId = new ResourceIdentifier(Guid.NewGuid().ToString(),
ResourceTypes.LayerDefinition, con.SessionID);
con.ResourceService.SaveResourceAs(ldef, resId);
--- end code ---
