I'm trying to convert a Dictionary< dynamic, dynamic > to a statically-typed one by examining the types of the keys and values and creating a new Dictionary of the appropriate types using Reflection. If I know the key and value types, I can do the following:

Type dictType = typeof(Dictionary<,>);

        newDict = Activator.CreateInstance(dictType.MakeGenericType(new Type[] { keyType, valueType }));

However, I may need to create, for example, a Dictionary< MyKeyType, dynamic > if the values are not all of the same type, and I can't figure out how to specify the dynamic type, since

typeof(dynamic)

isn't viable.

How would I go about doing this, and/or is there a simpler way to accomplish what I'm trying to do?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping. I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting… >>> More
