c# - 从sql中解析对象

Question

我已经创建了表格并将几行放入其中。有没有办法从表中解析我自己的对象？

class Human
{
    string name;
    int age;

    public Human(string name, int age)
    {
        this.name = name;
        this.age = age;
    }
}

-- create table    
string sql = "create table human (name varchar(20), age int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

-- insert sample data
string sql = "insert into human (name, age) values ('John', 20)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

-- get the data back from that table
string sql = "select * from human";
command = new SQLiteCommand(sql, m_dbConnection);
SQLiteDataReader reader = command.ExecuteReader();

while (reader.Read())

现在如何从我的阅读器中解析一个Human实例？

Answer 1

是的，你可以

其实很简单。 试试这个:

//Create Collection of Human to store the values
List<Human> Humans = new List<Human>();
while (reader.Read())
{
   //Create Human Object from Sql Reader
   Human h=new Human(reader.getString(0),reader.getInt(1));
   //Add the object to collection
   Humans.add(h);
}

Humans 会将您获得的所有 Human Object 排成一行。
