How to pass list value to a stored procedure insert query

public void InsertDataToDb()
    {
        string connectionString = ConfigurationManager.ConnectionStrings["connection"].
            ConnectionString;
        var records = GetRecords();

        using (SqlConnection conn = new SqlConnection(connectionString))
        {
            conn.Open();

            SqlCommand cmd =
                new SqlCommand(
                    "INSERT INTO TableName (param1, param2, param3) " +
                    " VALUES (@param1, @param2, @param3)");
            cmd.CommandType = CommandType.Text;
            cmd.Connection = conn;
            cmd.Parameters.Add("@param1", DbType.String);
            cmd.Parameters.Add("@param2", DbType.String);
            cmd.Parameters.Add("@param3", DbType.String);

            foreach (var item in records)
            {
                cmd.Parameters[0].Value = item.param1;
                cmd.Parameters[1].Value = item.param2;
                cmd.Parameters[2].Value = item.param3;

                cmd.ExecuteNonQuery();
            }

            conn.Close();
        }
    }
