c# - What is the difference between ref and out -

संभव डुप्लिकेट:

मुझे पता है कि रेफरी का इस्तेमाल फ़ंक्शन के बाहर चर के परिवर्तित मान को पारित करने के लिए किया जाता है, लेकिन यह कैसे बाहर से अलग है?

रिफ पैरामीटर को पारित करने वाला एक तर्क पहले ही आरम्भ किया जाना चाहिए। इसकी तुलना एक पैरामीटर से करें, जिसका तर्क स्पष्ट रूप से एक पैरामीटर को पारित करने से पहले आरम्भ नहीं करना है।

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

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...
