I recognize the steps you're going through, moving the upper to top and using the second ToString() inside the first ToString(). You taught me well!

Thank you Tim. I'm pleasantly surprised. An elegant solution at your fingers.

Thanks Tim for sharing and all the best

Thank you for this video.

Thanks Tim.

Good vid. I would probably create a value object to help remember the format type strings because for sure I will forget what set as the magic format strings. Example: MyPersonStringFormat.General.Value == “G”

Great video, are you planning to make a video to add the tooltip/docstring information for the IDE?

Lots of good stuff in this video! Is it good to add a break on the switch statements, even though you return? Also, wouldn't it be ok to not include the if statement checking if null or G since that should be handled on the default?

Hi Tim, Your code color setup is gorgeous. Especially the separation of parentheses and braces. Is there any special setup around to set all those colors or does it have to be set manually? Thanks in advance Lorenzo

Hey Tim, by any chance do you think you could please make a video on Filter attributes for ASP NET Core Web API: ActionFilterAttribute ExceptionFilterAttribute ResultFilterAttribute FormatFilterAttribute ServiceFilterAttribute TypeFilterAttribute I'd really appreciate it! Thanks for all your content, keep up the great work!

helpful!

Thanks for this video. I have a question. When we do a ToString() on a DateTime for example intellisense prompt us with a list of usable "token" with their meaning. Is there a way to document the code to offer such display of the user of our class (in an equivalent manner we can do to write an inline documentation by using /// on top of class element)?

Hi Tim, this was a great video. I have a question though. In the case of a format like "FF MM LL" how would you handle the middle name if it were a null value? The obvious answer is to insert nothing for the middle name in the final result, but then you would also have a double space in between the first and last names. Should/would this toString typically be expected to handle that?

Hey Tim, Did you say a while back the monthly pass is being fixed up to possibly be open a lot more often? Would be handy, always opens when I can't afford it.

Hi Tim, are you still updating the C# master course?

Question, is it going to be faster to use Replace where "FF" replace with full name and after that "F" replace with first letter and then move onto Last name and so on, by the away presentation is excellent all the best

Please create a one making in use of IFormatProvider

The meaning of the formatProvider stays unhandled ? It's just there, cause the interface is defined this way ?

maybe I'd do this token thing with string replace or regex. easier to read. (however, the for loop maybe performs better)

In your second example you could just remove the entire if statement. It would still return the same.

Why not just split the format string into its tokens, i.e. void Main() { string format = "T FF M LL"; var tokens = format.Split(' '); var person = new Person() { Title = "Mr.", FirstName = "Tim", MiddleName = "NotTelling", LastName = "Corey" }; StringBuilder output = new StringBuilder(); foreach(var token in tokens) { switch(token) { case "T": output.Append(person.Title); break; case "F": output.Append(person.FirstName[0]); break; case "FF": output.Append(person.FirstName); break; case "L": output.Append(person.LastName[0]); break; case "LL": output.Append(person.LastName); break; case "M": output.Append(person.MiddleName[0]); break; case "MM": output.Append(person.MiddleName); break; } output. Append(" "); } output. Dump(); } Mr. Tim N Corey is output This will reduce the processing substantially.
