I have a signalr hub well configured and communicating well with the client. But my hub method accepts parameters of a specific type, and the class representing this type has Pascal cased properties. As shown below:
public List<DataChanges> Changes { get; set; }
But when the client (Javascript client) calls this method, it passes the object correctly but, the Property of this object is always null unless I change the property's name to "CamelCase". As shown below:
public List<DataChanges> changes { get; set; }
What I tried:
I added the following attributes each at its own turn to the properties of the object, But the error persisted.
[DataMember(Name = "changes")]
[JsonProperty("changes")]
In my startup class, I added signalr json protocol as follows:
.AddNewtonsoftJsonProtocol(options =>
{
//options.PayloadSerializerSettings.ContractResolver = new SignalRContractResolver();
//options.PayloadSerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver { NamingStrategy = { OverrideSpecifiedNames = true } };
})
Here is the Signalr contract resolver:
public class SignalRContractResolver : IContractResolver
{
private readonly Assembly _assembly;
private readonly IContractResolver _camelCaseContractResolver;
private readonly IContractResolver _defaultContractSerializer;
public SignalRContractResolver()
{
_defaultContractSerializer = new DefaultContractResolver();
_camelCaseContractResolver = new CamelCasePropertyNamesContractResolver();
_assembly = typeof(Startup).GetTypeInfo().Assembly;
}
public JsonContract ResolveContract(Type type)
{
if (type.GetTypeInfo().Assembly.Equals(_assembly))
return _defaultContractSerializer.ResolveContract(type);
return _camelCaseContractResolver.ResolveContract(type);
}
}
I tried a few other solutions, but nothing worked. The camel case serialization could not be applied by signalr and my property was always null.
Can somebody please tell me a solution for this ?
