Similar to struct, union or hashtable in c++

Question

dear experts, this is similar to struct in c++ or union in C++ or hashtable, but can we can create an array in c# and store in it, various variable name and their type. if so, how do we do so. for further explanation...see example below. I want to be able to create anarray(not sure of the terminology to use) called arr and store in it 6, "boy", 'c', null and also its type, for example since 6 is an integer, i store number, since boy is a string, i store varchar2 as well...how do i got about writing a simple code for that. all help is appreciated. Finally, I would also like to pass such array(not sure of the terminology to use) as a parameter. Can someone please explain how to do this without cursors, a simple code will help. I need to understand the idealogy for learning purposes

that is not what i am looking for...I will try to expplain it further....First of all structure and array have nothing in common, so it is difficult to answer correctly when you say "similar to struct in c++ or union in C++ or hashtable". It looks like you need an object:
CREATE OR REPLACE
  TYPE param_set_type
    AS OBJECT(
              param1 NUMBER,
              param2 NUMBER, -- since second param in your example is NULL I don't know what type to use, so I used NUMER
              param3 VARCHAR2(100)
-- now I can use object type as procedure parameter type
CREATE OR REPLACE
  PROCEDURE P1(
               p_param_set param_set_type
END;
-- procedure call
BEGIN
    p1(
       param_set_type
                      6,
                      null,
                      'boy'
end;
/SY.
