Can actually achieve a simple collection class ... Or a lot of places are not enough,,, if you are fortunate to encounter experts also hope to help answer ...

1. The above examples can only produce local variables. It doesn't produce a global. How can i solve

Can I generate, I want variables, such as local, or global ...

2.public class Typedfilter:control The result is that after the control is deleted, the variable is not deleted

The above code is expected to help you, especially in doing this.
