C #3.0 new feature-automatically generate attributes

C # Since its birth, we have taken the lead of the family, and have thousands of pets in one, and are still famous . Net framwork A member of the family is naturally noble. Big brother in programming Java After more than a decade of development, it has been robust and powerful. Open Source Community Of SSH ( Struts + spring + hibernate ) Framework to make J2EE With unparalleled charm. Versatility, portability, and scalability are well supported. Every time we learn SSH I will give you a general idea later. Why? . Net There is no such excellent framework. Therefore. Net Fans also developed their own Sh ( Nspring + nhib.pdf ). But the two frameworks and . Net The programming style is always out of place. This is just something copied. But we do not need to be too pessimistic, C #3.0 The emergence of this feature has brought us a lot of new features. As for what new features, I will introduce them one by one.
First new feature: automatically generate attributes
Generally, we need to writeGET/SetTo provide external access and operations for attributes. For example:

 

 Code 

   Public     Class  Userinfo
{
  String  Username;
  String  Password;
  Public  Username
{
  Get  {  Return Username ;}
  Set  {Username  =  Value ;}
}
  Public  Password
{
  Get  {  Return  Password ;}
  Set  {  Return  Password  = Value ;}
}
}
 

 

We always envyEclipseIsJavaProperty is automatically generatedGeter/seterMethods, althoughVisual StudioIt can also be similar, but it is not convenient to use, especially when a class has many attributes, write theseGET/SetThe method is really annoying. WhileC #3.0Finally let us get rid of this nightmare, and you will find that it is a feature of the language itself, comparedJavaOfGeter/seterThe method should be simpler, simpler, and more natural. Microsoft has made a lot of effort in terms of details.
Okay. Let's see how to use it.C #3.0To compile the above class.

 -->  Public   class userinfo 
{< br>   Public     string   username {  Get  ;  set  ;}< br>   Public     string   password {  Get  ;  set  ;}< BR >}< br> 

We can find that this is too easy. We only need to addGET/SetThe two keywords are used to write a few rows.Code.. Net framworkIt will automatically generate its private attributes for us. Using it is the same as using the above class.

 

Code


   Userinfo=NewUserinfo ();
Userinfo. Username="Test ";
Userinfo. Password="Test ";
 

Now, we canJavaFans show off. Haha, just kidding.
