asp.net - How to refresh singleton in C# -

asp.net - How to refresh singleton in C# -

I have a singleton that gets from DB, so it is a costly load, it is full of laziness.

I would like to make a method that refreshes the singletons and once it is necessary, it should be populated.

The data is DB and is very expensive, so I want if I have concurrent calls, then refresh it only once (this is, if I get calls to refresh 500, then I just once wants to restart the refresh I)

  public static Pejdata example {get (m_Instance == null) {lock (instanceLock) {If (m_Instance == nULL) {m_Instance = New PageData ( ); }}} Return m_Instance; }} Public Zero ReSync () {lock (instanceLock) {/ * To re-install the installation to re-create the setting * / m_Instance = null; Pageadata pData = example; }}    thanks   
 
   This is a bit wrong , Your   
  if (m_Instance == faucet)   
 really should be inside the lock.  
 Sorry, did not pay attention to it.  
 Nothing has been made that will allow other clients to quietly leave the call. If you are already refreshing the timeout will create an exception that I think. Perhaps maintain a stale date time that you can check to avoid refreshing those who make queued calls.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
