我有一个场景.
所需的输入和输出是JSON.
// Input
{
"OldObject": {
"Time": 1351160457922,
"Name": "OName",
"quantity": 100,
"price": 10
}
}
// Output
{
"NewObject": {
"Time": 1351160457922,
"Title": "OName",
"quantity": 100
}
}

我需要一些转换代码或最好是xslt类型语言来将json从一种格式转换为另一种格式.这个变压器也需要快速,因为转换将在运行中完成.
编辑
我没有收到INPUT对象的定义,它可能在运行时更改.但如果需要,我可以使用OUTPUT对象的类.我试图以json - > xml - > xslt - > xml - > json的方式执行此操作,但此时每秒接收大约1000个对象,此过程可能会产生开销.
我也不能使用JavaScript,因为myApp是基于Windows的简单java应用程序,使用JavaScript可能会导致开销.
我是c#中配置部分的初学者,
我想在配置文件中创建自定义部分.我在谷歌搜索后尝试的是如下
配置文件:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="MyCustomSections">
<section name="CustomSection" type="CustomSectionTest.CustomSection,CustomSection"/>
</sectionGroup>
</configSections>
<MyCustomSections>
<CustomSection key="Default"/>
</MyCustomSections>
</configuration>

当我使用此代码检索Section时,我收到一条错误说配置错误.
var cf = (CustomSection)System.Configuration.ConfigurationManager.GetSection("CustomSection");

我错过了什么?

Run Code Online (Sandbox Code Playgroud) 我有一个复杂的情况,我需要用NHibernate映射三个不同的类.Class1(Branch.cs)具有Class2(Employee.cs)对象的集合.同时Class2还有一个Class3(Contacts.cs)对象的集合.
由于数据非常庞大,我使用fetch关键字在单个查询中检索数据.
我使用查询作为
Query1 - "从分支b内部联接获取b.Employee e内部联接获取e.Contacts" - 单个查询但重复的结果.
Query2 - "来自分支b内部联接获取b.Employee" - 多个查询,需要的结果.
我在映射文件中使用了包.查询结果似乎有重复的结果.如何删除重复的结果以及在单个查询中检索数据.我包括映射文件和类.
