PostSharp C#-如何实现所有必需字段

你可以实现 PostSharp.Aspects.IAspectProvider :

public class AllFieldsRequiredAttribute : TypeLevelAspect, IAspectProvider
{
    IEnumerable<AspectInstance> IAspectProvider.ProvideAspects(object targetElement)
    {
        Type type = (Type)targetElement;
        return type.GetFields().Select(
           m => new AspectInstance(m, new ObjectConstruction(typeof(RequiredAttribute))));
    }
}

[AllFieldsRequired]
public class Foo
{
    public string Bar;
    public object Baz;
}
