I have a model I'm using in a Microsoft.AspNetCore.OData Web API that has System.Net.IpAddress as a property. I need the OData controller to serialize/deserialize the IP address as a string.
Here is an example of the model:
public class TestModel
{
public int Id { get; set;}
public IPAddress Ipaddress { get; set;}
}
And a simple example of generating the Edm Model for it:
public class EdmModel
{
public IEdmModel GetEdmModel()
{
var builder = new ODataConventionModelBuilder();
var ip = builder.ComplexType<IPAddress>();
//ip.Ignore(i => i.Address);
ip.Ignore(i => i.AddressFamily);
ip.Ignore(i => i.IsIPv4MappedToIPv6);
ip.Ignore(i => i.IsIPv6LinkLocal);
ip.Ignore(i => i.IsIPv6Multicast);
ip.Ignore(i => i.IsIPv6Teredo);
ip.Ignore(i => i.IsIPv6UniqueLocal);
ip.Ignore(i => i.ScopeId);
var model = builder.EntitySet<TestModel>("TestModel").EntityType;
model.ComplexProperty(p => p.Ipaddress).IsRequired();
return builder.GetEdmModel();
}
}
The controller returns a json representation of the IP address structure but I need it as a string.
I've tried to write and inject a json converter but the OData doesn't use it. I also need to figure out how to show the OData XML schema to use a string instead of the IP address complex type.
Here's the json converter (that works on it's own just not through the OData API):
public class IpAddressJsonConverter : JsonConverter<IPAddress>
{
/// <inheritdoc/>
public override IPAddress Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
{
return IPAddress.Parse(reader.GetString());
}
/// <inheritdoc/>
public override void Write(Utf8JsonWriter writer, IPAddress value, JsonSerializerOptions options)
{
writer.WriteStringValue(value.ToString());
}
}
