Check if Object is Dictionary or List

Question

Working with .NET 2 in mono, I\'m using a basic JSON library that returns nested string, object Dictionary and lists.

I\'m writing a mapper to map this

Modifying the above answer. In order to use GetGenericTypeDefinition() you must preface the method with GetType(). If you look at MSDN this is how GetGenericTypeDefinition() is accessed:

public virtual Type GetGenericTypeDefinition()

Here is the link: https://msdn.microsoft.com/en-us/library/system.type.getgenerictypedefinition(v=vs.110).aspx

public bool IsList(object o)
{
    return o is IList &&
       o.GetType().IsGenericType &&
       o.GetType().GetGenericTypeDefinition().IsAssignableFrom(typeof(List<>));
}

public bool IsDictionary(object o)
{
    return o is IDictionary &&
       o.GetType().IsGenericType &&
       o.GetType().GetGenericTypeDefinition().IsAssignableFrom(typeof(Dictionary<>));
}
