public DataTable GetData()
{
    DataTable table = new DataTable("Table");
    using (sqlConnection connection = new sqlConnection("Connection string"))
    {
        sqlCommand command = new sqlCommand();
        command.Connection = connection;
        command.CommandType = System.Data.CommandType.Text;
        command.CommandText = "query string";

        connection.Open();
        sqlDataAdapter adapter = new sqlDataAdapter(command);
        adapter.Fill(table);
    }
    return table;
}

但它返回DataTable,我想选择List而不是DataTable.像这样：

public List<MyClass> GetData()
{
    DataTable table = new DataTable("Table");
    using (sqlConnection connection = new sqlConnection("Connection string"))
    {
        sqlCommand command = new sqlCommand();
        command.Connection = connection;
        command.CommandType = System.Data.CommandType.Text;
        command.CommandText = "query string";

        connection.Open();
        sqlDataAdapter adapter = new sqlDataAdapter(command);
        adapter.Fill(table);
    }
    ...
    return [List of MyClass];
}

我怎样才能做到这一点？

谢谢！
