How to assertValue input array

wish of those help Just because it's not available from "Show All Available Commands" does not necessarily mean you'll not be able to use it. Add a command to the IDE and select it in the sequence of operations in your test (i.e. from the "Table" view not the "Source" view). Now you'll see the "Command", "Target" and "Value" for your selected operation; just change the command to the one you require.

wish help you to fix your issue Looks like you're only retrieving one column in your select query but you're adding a 2 column array to you're new row.
You may be able to get away with the below:

DataRow dr;
CommonDBTransaction c = new CommonDBTransaction();
string sql = "SELECT MId FROM Module";
DataTable dt = c.searchData(sql);
dr = dt.NewRow();
dr[0] = "--Select Module--";
dt.Rows.InsertAt(dr,0);
metroComboBoxMod.ValueMember = "MId";
metroComboBoxMod.DisplayMember = "MId";
metroComboBoxMod.DataSource = dt;

DataRow dr;
CommonDBTransaction c = new CommonDBTransaction();
string sql = "SELECT MId AS MId, MId AS DisplayId FROM Module";
DataTable dt = c.searchData(sql);
dr = dt.NewRow();
dr[0] = 0;
dr[1] = "--Select Module--";
dt.Rows.InsertAt(dr,0);
metroComboBoxMod.ValueMember = "MId";
metroComboBoxMod.DisplayMember = "DisplayId";
metroComboBoxMod.DataSource = dt;

With these it helps First of all, make the user experience as good as possible. Inputing a matrix all at once can be error prone, make the user's life easier and take it step by step.
Second, make small methods that perform simple tasks; they are easier to reason about, easier to write, easier to debug and easier to modify if new requirements come along. Don't make methods do too much, it will only buy you headaches and more debugging hours than necessary. If you are learning, don't worry if it seems you are breaking down to seemingly absurdly simple tasks, you wont regret it. Always remember that the most complicated problems you can imagine are always solved solving smaller and easier ones.

it fixes the issue I have a requirement where I need to pass the nested array of objects as an input to stored procedure , get the data from table as group of different date ranges, and return all the date ranges data as an output. I am a newbie in PL/Sql , so request your guidance here . , Oracle Setup:
Create a collection to input:

CREATE TYPE intlist AS TABLE OF int;

CREATE TYPE daterange AS OBJECT(
  start_date DATE,
  end_date   DATE
);
/
CREATE TYPE daterangelist AS TABLE OF daterange;

CREATE TABLE test_data ( id, start_date, end_date ) AS
  SELECT 1, DATE '2019-01-01', DATE '2019-01-02' FROM DUAL UNION ALL
  SELECT 2, DATE '2019-01-02', DATE '2019-01-03' FROM DUAL UNION ALL
  SELECT 3, DATE '2019-01-03', DATE '2019-01-04' FROM DUAL UNION ALL
  SELECT 4, DATE '2019-01-04', DATE '2019-01-05' FROM DUAL;

CREATE PROCEDURE test_proc (
  i_ints  IN  intlist,
  o_dates OUT daterangelist
)
IS
BEGIN
  SELECT daterange( start_date, end_date )
  BULK COLLECT INTO o_dates
  FROM   test_data
  WHERE  id MEMBER OF i_ints;
END;
/

DECLARE
  p_ranges daterangelist;
BEGIN
  test_proc( intlist( 1, 3, 4 ), p_ranges );
  FOR i IN 1 .. p_ranges.COUNT LOOP
    DBMS_OUTPUT.PUT_LINE( p_ranges(i).start_date || ' - ' || p_ranges(i).end_date );
  END LOOP;
END;
