This update reportedly causes a crash for some older .NET applications: Microsoft warns users: Uninstall Windows 11 KB5012643 if it crashes your apps I ran into this issue a couple days ago and took a dive to see what the cause might be. I noticed that there's a missing entry for...

C# 7.0 Switch Case (Pattern Matching)

Apparently C# 8.0 comes out with recursive patterns and expressions now for switch statements. :eek: Not quite sure how this will translate to the C# language in practice though just like the idea of Tuples. Seems like a very rare case, especially if you want to promote code readability. I see...

C# 7.0 Switch Case (Pattern Matching)

A really cool feature that I've been starting to use more frequently is pattern matching which also is cleanly implemented for switch statements in C#. Example: switch (_commTransport) { case TerminalDebugClient _: ((TerminalDebugClient)_commTransport).HostValidation +=...

CodeJam Qualification Round

So it just finished and I attempted late last night and continued late today. I wish I would have spent more time on the questions. I had the first 2 down and the cubic one I was close to solving but I spent too much time doing research because my simple polygon function wasn't proper lol...

C# Generic Trie/Prefix Tree Implementation

One slight adjustment that could be made, is to remove the class constraint for reference types and replace the null assignments with default(T) too so this can be used with value types.

C# Generic Trie/Prefix Tree Implementation

As I said, the internal object with this generic class must implement the INamedValue interface so it can be used:

C# Generic Trie/Prefix Tree Implementation

So I needed some implementation that would allow me to lookup string values and branch results off based on what I was looking for. Typically this is the appropriate job for what is called a Trie or otherwise a Prefix Tree. You may look up "A" then "AB" then "ABC" and with each additional...

How to renumber filenames?

Yes - I understand. It is still possible with batch scripting though. You can do substrings in batch, compare against digits, find the separator, and rename with the incremented number and the original filename + extension. Renaming a file doesn't change the last modified date.

[SOLVED] RegEx (Regular Expression) issue

That's because my pattern was manipulated incorrectly. I had (?<= ).[^\[\]\{\}]*?(?= ) not (?<= ).[^\[\]\{\}]*?(?<= ) <- which is invalid. I had a look AHEAD there not a look BEHIND -- before you guys added which wasn't specified by you in the first post. You only specified...

You can do this with a batch script and the dir command if you sort the files and rename each with an incremented variable.

[SOLVED] RegEx (Regular Expression) issue

That's because originally you posted between and not and . It seems your question was missing pieces; you're not going to get the right answer. I'm still confused on this though as your description of what you were trying to match still isn't clear to me. Glad you got it working

[SOLVED] RegEx - Anyone know how to do this?

If the first 2 digits is always a length of 2 and you want to ensure that you have digits after the '-' you should change it to this: \d{2}-\d+ \d* can match 0 or more digits so that may not be entirely suitable.

C# Basic Generic Publisher/Subscriber Demo

I had to write a basic but re-usable implementation of a pubsub methodology, since I didn't have access to Rx for .NET or anything like that, so I came up with some basic interfaces to achieve this and wrote up a quick demo before I rolled it into my production module that I was working on for...

Hold on. Above you're trying to match with another tag, but here you say you want to match with either or , so which one is the correct one? edit: This one seems to work for the first post: You were negating \ which was contained in the first one.
