【问题描述】:
今天我学到了这个
JavaScriptSerializer ser = new JavaScriptSerializer();
Foo foo = ser.Deserialize<Foo>(jsonSz);
我必须将类与从远程站点提取的 json 进行匹配。它节省了我很多时间,我可以只编写类而不用担心处理数据并将它们放入类中。我也不需要到处使用属性。 Example here
是否有一个我可以用于 T-SQL 的库(我希望它支持 MySQL 和 SQLite),以允许我编写如下所示的类并轻松执行类似的操作
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
