ASP.Net 3.5和4.0之间的关键区别是什么?
阅读ASP.NET 4.0中新增内容的白皮书: http : //www.asp.net/learn/whitepapers/aspnet4 。
Here are a few from a quick search on Google:
1) Client Data access:
ASP.NET 3.5: There is no direct method to access data from client side. We can go for any of these methods ASP.NET 4.0: In this framework there is an inbuilt feature for this. Following are the methods to implement them.
2) Setting Meta keyword and Meta description:
Meta keywords and description are really useful for getting listed in search engine.
ASP.NET 3.5: It has a feature to add meta as following tag ASP.NET 4.0: Here we can add the keywords and description in Page directives itself as shown below.
3) Enableviewstage property for each control
ASP.NET 3.5: this property has two values “True” or “false”
ASP.NET 4.0: ViewStateMode property takes an enumeration that has three values: Enabled, Disabled, and Inherit.
4) Setting Client IDs
Some times ClientID property creates head ach for the programmers.
ASP.NET 3.5: We have to use ClientID property to find out the id which is dynamically generated ASP.NET 4.0: The new ClientIDMode property is introduced to minimize the issues of earlier versions of ASP.NET.
