I have a generic class in C#, like this:
public class GenericClass<T> { ... }
Now, I have the Type object for an object, and would like to, through reflection or otherwise, to get the Type object for GenericClass<T> where T corresponds to that Type object I have my object.
Like this:
Type requiredT = myobject.GetType();
Type wantedType = typeof(GenericClass<requiredT>);
Obviously this syntax doesn't work, but how do I do it?
Yes, you can:
Type requiredT = ...
Type genericType = typeof(GenericClass<>);
Type wantedType = genericType.MakeGenericType(requiredT);
This will give you the GenericClass<T> Type object, where T corresponds to your requiredT.
You can then construct an instance using Activator, like this:
var instance = Activator.CreateInstance(wantedType, new Object[] { ...params });
Type requiredT = myobject.GetType();
Type genericType = typeof(GenericClass<>);
Type wantedType = genericType.MakeGenericType(requiredT);
Type wantedType = typeof(GenericClass<>).MakeGenericType(requiredT);
