How to read baseclass attribute

[snehabihani]

[AttributeUsage(validOn: AttributeTargets.Field, AllowMultiple = true, Inherited = true)]
public class OutputExecutionPortAttribute : BasePortAttribute
{
}
public class BasePortAttribute : Attribute
{
        public string Description { get; set; }
}
    
[OutputExecutionPort] public Func<Task> OnNext;

I want to get attribute "OutputExecutionPort" properties including base class.
Please help

If I understood you correctly, you are looking to find all the properties of an attribute attached to a field, including the properties defined in any of its base classes.

Assuming you have your field stored in a FieldDefinition field, you can get its custom attributes and its corresponding type definition using something like the following:

var attribute = field.CustomAttributes.First(x => x.Constructor?.DeclaringType.Name == "OutputExecutionPortAttribute");
var type = attribute.Constructor.DeclaringType.Resolve();

Then, it is a matter of iterating all its properties, while also iterating all base types of the type:

var properties = new List<PropertyDefinition>();
while (type is not null)
{
   properties.AddRange(type.Properties);
   type = type.BaseType?.Resolve();
}

yes. Thanks for quick reply. One more last query in below I need all ConfigurationParameter when I start with TestNode Class TestNode : PlatformVisualNode<TestNodeConfiguration> {} public class TestNodeConfiguration : BaseNodeConfiguration { [ConfigurationParameter] public string text { get; set; } } public class BaseNodeConfiguration : BaseConfiguration { [ConfigurationParameter] public bool IsProvider { get; set; } } public class BaseNodeConfiguration :Interface { [ConfigurationParameter] public bool IsProvider1 { get; set; } }

It would be a similar approach, where you'd traverse all types, their properties and read their custom attributes. You can read more about traversing the member tree on this page. Also, PlatformVisualNode<TestNodeConfiguration> is going to be a TypeSpecification with a TypeSignature in it, you may also want to have a look at the docs on type signatures as well :).

Can you please help with typesignature ? Today i was struggling to get that

You have to be a bit more specific with what you'd need help with 😅. What part do you struggle with?

PlatformVisualNode<TestNodeConfiguration> is going to be a GenericInstanceTypeSignature wrapped in a TypeSpecification. You'd have to check whether the type's base type is such a type specification, and act accordingly.
