Reflective Generic Detection
- by Aren B
Trying to find out if a provided Type is of a given generic type (with any generic types inside)
Let me Explain:
bool IsOfGenericType(Type baseType, Type sampleType)
{
/// ...
}
Such that:
IsOfGenericType(typeof(Dictionary<,>), typeof(Dictionary<string, int>)); // True
IsOfGenericType(typeof(IDictionary<,>), typeof(Dictionary<string, int>)); // True
IsOfGenericType(typeof(IList<>), typeof(Dictionary<string,int>)); // False
However, I played with some reflection in the intermediate window, here were my results:
typeof(Dictionary<,>) is typeof(Dictionary<string,int>)
Type expected
typeof(Dictionary<string,int>) is typeof(Dictionary<string,int>)
Type expected
typeof(Dictionary<string,int>).IsAssignableFrom(typeof(Dictionary<,>))
false
typeof(Dictionary<string,int>).IsSubclassOf(typeof(Dictionary<,>))
false
typeof(Dictionary<string,int>).IsInstanceOfType(typeof(Dictionary<,>))
false
typeof(Dictionary<,>).IsInstanceOfType(typeof(Dictionary<string,int>))
false
typeof(Dictionary<,>).IsAssignableFrom(typeof(Dictionary<string,int>))
false
typeof(Dictionary<,>).IsSubclassOf(typeof(Dictionary<string,int>))
false
typeof(Dictionary<,>) is typeof(Dictionary<string,int>)
Type expected
typeof(Dictionary<string,int>) is typeof(Dictionary<string,int>)
Type expected
typeof(Dictionary<string,int>).IsAssignableFrom(typeof(Dictionary<,>))
false
typeof(Dictionary<string,int>).IsSubclassOf(typeof(Dictionary<,>))
false
typeof(Dictionary<string,int>).IsInstanceOfType(typeof(Dictionary<,>))
false
typeof(Dictionary<,>).IsInstanceOfType(typeof(Dictionary<string,int>))
false
typeof(Dictionary<,>).IsAssignableFrom(typeof(Dictionary<string,int>))
false
typeof(Dictionary<,>).IsSubclassOf(typeof(Dictionary<string,int>))
false
So now I'm at a loss because when you look at the base.Name on typeof(Dictionary) you get
Dictionary`2
Which is the same as typeof(Dictionary<,>).Name
