C＃2010、ODP.net、配列を渡すストアドプロシージャを呼び出す

（簡単な方法）から始めることができます：

List<int> idList = yourObjectList;
List<int> nameList = yourObjectList;

using (OracleConnection oraconn = new OracleConnection())
{
    oraconn.ConnectionString = "Your_Connection_string";

    using (OracleCommand oracmd = new OracleCommand())
    {
        oracmd.Connection = oraconn;

        oracmd.CommandType = CommandType.StoredProcedure;
        oracmd.CommandText = "Your_Procedura_name";
        oraconn.Open();

        // To use ArrayBinding, you need to set ArrayBindCount   
        oracmd.BindByName = true;
        oracmd.ArrayBindCount = idList.Count;

        // Instead of single values, we pass arrays of values as parameters   
        oracmd.Parameters.Add("ids", OracleDbType.Int32, oyourObjectList.ToArray(), ParameterDirection.Input);
        oracmd.Parameters.Add("names", OracleDbType.Varchar2, oyourObjectList.ToArray(), ParameterDirection.Input);

        oracmd.ExecuteNonQuery();
        oraconn.Close();
    }
}

次に、dbにパッケージ/プロシージャを追加します：

PROCEDURE Your_Procedure_name(
      name IN VARCHAR2,
      id IN NUMBER
      )    IS     
BEGIN

    INSERT INTO your_table VALUES( id, name);
END Your_Procedure_name;

別のオプションは次のとおりです：

using (OracleConnection oraconn = new OracleConnection())
{
    oraconn.ConnectionString = "Your_Connection_string";

    using (OracleCommand cmd = new OracleCommand())
    {

        cmd.Connection = oraconn;

        cmd.CommandType = CommandType.StoredProcedure;
        cmd.CommandText = "Your_Procedure_name";
        oraconn.Open();


        OracleParameter idParam = new OracleParameter("i_idList", OracleDbType.Int32, ParameterDirection.Input);
        idParam.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
        idParam.Value = idList.ToArray();
        idParam.Size = idList.Count;

        OracleParameter nameParam = new OracleParameter("i_nameList", OracleDbType.Varchar2, ParameterDirection.Input);
        nameParam.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
        nameParam.Value = nameList.ToArray();
        nameParam.Size = nameList.Count;

        // You need this param for output
        cmd.Parameters.Add("ret", OracleDbType.RefCursor).Direction = ParameterDirection.Output;
        cmd.Parameters.Add(idParam);
        cmd.Parameters.Add(nameParam);

        conn.Open();

        //If you need to read results ...
        using (OracleDataReader dr = cmd.ExecuteReader())
        {
            while (dr.Read())
            {
                ...
            }
        }
        conn.Close();
    }
}

ただし、

TYPE integer_list IS TABLE OF Your_table.id_column%TYPE INDEX BY BINARY_INTEGER;
// same for names

create or replace TYPE T_ID_TABLE is table of number; 

そして、

PROCEDURE Your_Procedure_name(
      v_ret IN OUT SYS_REFCURSOR,
      i_idList integer_list,
      i_nameList string_list)
  IS  
  begin
    -- Store passed object id list to array
 idList T_ID_TABLE := T_ID_TABLE(); 
  ...
  begin

    -- Store passed object id list to array
    idList.Extend(i_idList.Count);
    FOR i in i_idList.first..i_idList.last loop
     idList(i) := i_idList(i);
    END LOOP;    

    ...
END Your_Procedure_name;
