今天我学到了这个
JavaScriptSerializer ser = new JavaScriptSerializer();
Foo foo = ser.Deserialize<Foo>(jsonSz);
我必须将这个类与我从远程站点拉出的json相匹配。它节省了我很多时间,我可以编写类,而不用担心处理数据并将它们放入类中。我也不需要在任何地方使用属性。 Example here
是否有可用于T-SQL的lib(我希望支持MySQL和SQLite)允许我编写类似下面的类并轻松做类似的事情
results = doSomething<User>(@"select id WHERE username=? password=?", user, hash(pass));
//results is null or results.id is the only initialize value.
class User
{
[primary_key]
long id;
string username;
byte[] password;
DateTime create, lastLogin;
string? signature; //the only column that is allow to have null.
//etc
}
class Comment
{
[primary_key]
long id;
User author; //automatically uses user as a reference foreign key
Comment parent; //may be 0 to stand for root. But all PK start at 1 so does this cause trouble when using foreign keys?
DateTime post;
string comment;
}
//I have no idea how a query for a comment with each of its children comment going 5 deep would look like
//I wouldn't mind writing all SQL queries

您需要的是对象关系映射框架,例如NHibernate或Subsonic。
维基百科有一个很好的list of ORM frameworks for .NET。

看看linq-to-sql,这个站点运行的映射器。
