Top 26 c# advanced interview questions and answers | Hindi

In this video I have discussed top 26 frequently asked interview questions on advance c#. This list is based on what I have experienced in interview and I am sure it will definitely going to help you as well.

I have missed to include one question from the list in the video
FirstOrDefault vs SingleOrDefault method
FirstOrDefault method will return null if there is no result in the list or collection where as SingleOrDefault will throw excpetion when there is no result in the list or collection. This point is enough to convince interviewer.
Apology for not including this in the video.

Also I have mistakenly explained the func delegate.. the correction is the last parameter in type is return type not the first as explained in the video..
Hope this will correct the mistake....

So if you enjoy the video and it added any value to your knowledge then do like it and don't forget to subscribe the channel.

Hello @simply teching, Nice.🙂, In Func Delegate example there is a mistake in explanation of parameters return type, in Func Delegate always last parameter will be a return type.
