How do I check if a property exists on a dynamic anonymous type in c#?

Question

I have an anonymous type object that I receive as a dynamic from a method I would like to check in a property exists on that object.

....
var settings = new

None of the solutions above worked for dynamic that comes from Json, I however managed to transform one with Try catch (by @user3359453) by changing exception type thrown (KeyNotFoundException instead of RuntimeBinderException) into something that actually works...

public static bool HasProperty(dynamic obj, string name)
    {
        try
        {
            var value = obj[name];
            return true;
        }
        catch (KeyNotFoundException)
        {
            return false;
        }
    }

Hope this saves you some time.
