Finding Generic Type Parameter through reflection [duplicate]

I'm new to Reflection and Im just trying cool little ideas.

I'm trying to see if there is a way to find the type that a property is and pass it through a generic type parameter? If it's not possible that's ok, just would be fun to play around with, even if it's not that efficient

I have the field type, just need to have a way to convert it so it's acceptable by the compiler, unless generic type parameters need to be hard coded.

Here is an example of what I want to do:

foreach(FieldInfo f in typeof(ActivityData).GetFields())
{ 
    Database.GetData</*Do something here?*/>(nReader, "");
}

rtn.ActionID = Database.GetData<int>(nReader, GetAttribute<DBAttribute, ActivityData>(nameof(this.ActionID)).ColumnName);

So the last line is what I want to do, but for each field inside of my object, however, I'm not sure how to get the generic type parameter through reflection, or if its possible at all.
