HotChocolate:如何使用[ExtendObjectType]将指令绑定到解析程序中的字段

Question

想象一下这个ObjectType带有字段"条"；来自FooResolver，带有BazDirective 注释

public class FooResolver {
public IEnumerable<Bar> GetBars(string name) {/*omitted*/}
}

public class FooType: ObjectType<Foo>
{
protected override void Configure(IObjectTypeDescriptor<Foo> descriptor) {
descriptor.Field<FooResolver>(_ => _.GetBars(default)).Directive<BazDirective>();
} 
} 

如果我们使用扩展绑定

class FooType: ObjectType<Foo> {}
[ExtendObjectType(Name="Foo")]
class FooResolver {
[/* how to bind BazDirective? */]
public IEnumerable<Bar> GetBars(string name) {/* omitted */}
}

如何绑定BazDirective？

解决方案使用自定义DescriptorAttributes，可用于在字段中添加额外信息。
