C#: Regular Expressions with object arrays instead of strings

Question

Is there something that I can use to search for object patterns in an list or array of objects instead of characters in a string?

I mean search if there is a match where you find object1 one time followed by 3 times object 2. Similar to the way we use it for strings.

Regular expressions are for strings only. For your problem there is different solutions. For small set of data I would simply use a for-loop. — M.Hazara

It will get more complex. And I really don't like the idea to write something like RegEx be myself. — be_mi

What about Selecting each object to a char, transforming the list of objects into a string? — Sweeper

That's an option. Currently planning to build an "RegEx" for objects myself. — be_mi

So you want to find patterns based on the type of objects in an array. You could turn the list into a string with a character for each object, use regex to get a Match, then return the object at the Match's index.

It's not only the type, but also the values of some properties. But it might be a possibility.

In a very generic sense, you can turn your array of objects to JSON, then regex that, only it will take some effort to turn that match back to your original object. If you convert each object into a same length character string, then you can use division to find your original item. Having a unique id for each object would work for the JSON option, I guess...
