您需要参考SqliteDataReader

static void Main() 
{
    string cs = "URI=file:test.db";

    using(SqliteConnection con = new SqliteConnection(cs))
    {
        con.Open();

        string stm = "Select * from ContryLookup";

        using (SqliteCommand cmd = new SqliteCommand(stm, con))
        {
            using (SqliteDataReader rdr = cmd.ExecuteReader())
            {
                while (rdr.Read()) 
                {
                    Console.WriteLine(rdr.GetInt32(0) + " " 
                        + rdr.GetString(1) + " " + rdr.GetInt32(2));
                }         
            }
        }

        con.Close();   
     }
}

你有一个名为Execute的执行程序吗？执行所需操作的一种方法是使用ExecuteReader过程并将其返回给DataReader对象。然后使用for循环遍历数据：

string sql = "select * from table";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
SQLiteDataReader reader = command.ExecuteReader();
while (reader.Read())
       Console.WriteLine(reader["columnName"]);
