C# Reflection Explained (Claim generation example)

In this c# reflection tutorial I try to answer questions like: what is reflection? how to use reflection? how to solve problems with reflection? Primarily I try to shift your perspective to looking at your code as just another source of data which we manipulate using reflection. We then go to implement a real world example, where we generate all possible claims we would need and authorize based on generated claims.

@@RawCoding simple explanation that worked for me is that reflection is just reading a section of metadata, which .NET adds to compiled assemblies

having this comment pinned is the real self-reflection

Thank you for sharing an explanation that clicked for you

[@faanross]

subbed just cause you pinned this comment, a man with intellectual humility.

[@evrame.microwize]

Thank you very much for the time and effort you put for people to learn. Obviously not a lot of people understand how hard it is to acquire the knowledge you have digested and shared to the community in such a great way. Again, thanks and keep up the awesome work!

[@vladm6892]

Always wanted to take a closer look into reflection. I will take a look at the video later today, thanks for posting!

[@RawCoding]

Hope it helps :)

Hi, Thanks Anton for all the awesome content on your channel. Which LinqPad extension did you use for ConvertTo() ? Also, how did you gain some much knowledge in C#? any recommendations ?

[@RawCoding]

public static T ConvertTo(this string @this) => JsonSerializer.Deserialize(@this); and just practice :)

[@RawCoding]

Sure :)

[@SpicyMelonYT]

Ok that intro and that phrasing was literally all I needed to immediately know that this was gonna be a great explanation. Its like you can read my mind in the beginning wth. Edit: After watching it all I was genuinely shocked at the similarities of how our minds work. I explain things just like you do and now I realize why people find it hard to understand me sometimes haha. I understood you though. Your explanation was basically 80% abstract thought and 20% communicational conventions (i.e. what we all agree on when we say words). I really wish there was a way to just send abstract thought over to someone else instead of trying to compress it down into words.

[@RawCoding]

Really appreciate your comment thank you 🙏

[@caglarcansarikaya1550]

Bro thanks for tour :) that was great, ı wonder about it was a show how we can do with reflection or it was a real scenario, I came here because I am looking something in reflection I would like put many of strings into one string with reflection, like property names are name1,name2, name3.. I dont know how much it is, when I read this from excel, I have to put all that to one list names

[@RawCoding]

Sorry I don’t quite understand

[@caglarcansarikaya1550]

Haha me too :) I dont know what I was trying to say, but I wonder about the auth claim with reflection is really needed or it is a show to see what we will do with using reflection

[@RawCoding]

It’s a demonstration

[@caglarcansarikaya1550]

@@RawCoding Okey, thanks for it. Reflection is really interesting :)

[@Eddyi0202]

Another great video, thanks for this! One thing is that I guess you could set "inherit" parameter to true of "GetCustomAttribute()" in order to get that "Authorize" attribute from the controller itself, instead of adding " || x.DeclaringType.GetCustomAttribute(authAttr) != null)".

[@RawCoding]

Thank you

[@LarryPeteet]

14:45 I downloaded your code and it compiles. When I try the Startup(null) like you show it cannot find Startup. I added the WebApp.dll from Bin folder but it doesn't see any namespaces there.

[@RawCoding]

If you don’t have a payed version of LinqPad you need to add the namespace manually, press f4 and it’ll be there

[@LarryPeteet]

@@RawCoding Thanks I had tried that but my problem was I was not using LINQPad as your project is DotNet Core. Just got it working and continuing with video, Kindly!

Ah alright

Damn, when excatly are you explaining what is the reflection? I watched the whole video carefully and I feel like I missed something because it ended and I still don't know what the reflection is exactly :/

[@RawCoding]

Code is data, you’ve written a program and there is data you can extract from you program. Reflection is reading data about your program at runtime.

[@sanjayi6245]

Please make a video on Reflection.Emit if possible

[@RawCoding]

I never used it so I can't sorry :)

seems like getting project for a Coursework that involves reflection wasn't the best idea

They way you typed it doesn't work for me. I had to use Single Quotes in the Split Parameter. "Hello World".Split(' ').Dump();

that's what json is gotta escape the " to not close of the string
