c# - Preferred method to set the value of a get only Property: constructor vs backing field -

-

edit : Although I have accepted the answer, the answer should also be considered correct.

Which method is preferred for setting the read-only value? Property: Using the backing field or using Constructor? Assuming that the design is for a property and there is no area (in the future, there may be an update for which the property needs to set up a setter which has to be stopped using a field).

Given the simple example, which method is preferred? If someone is favorite over another, then why?

Option 1 (backing field) : 

  class some object {// logic} square fu {Private SomeObject _myObject; Public SomeObject MyObject {get {if (_myObject == empty) {_myObject = new SomeObject (); } Back _myObject; }} Public Foo () {// logic}}

Option 2 (constructor) : 

  class SomeObject {/ / Logic} class Foo {public SomeObject MyObject {get; Private set; } Public Foo () {MyObject = new SomeObject (); // logic}}  
 
 
 It depends on the time required by the new SomeObject () , "And the probability is that the recipient is being called. 
 
 If MyObject is expensive to make, and every time you make an example of Fu (), option 1 is a good idea, and that the lazy preliminary startup time is to reduce Google Programs like Chrome are very heavy to use. 
 
 If you are going every time to create MyAbages every time, and the recipient is often called, then you will compare with each option on option 2.

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
