Removing certain characters from strings and converting to a list

Question

Hello!

I am sending query data from Unity3D to an external API. The API is taking my query, generating a result and sending it back.

However when it sends back certain values, it sends them back like this:

["c7385f31-2c3e-42ae-aae2-57c5ea66088f", "e6f8f4db-76c4-43a9-b5d3-5d3be606cabd", "22a55fa7-bf1f-46d9-9c1e-67336c4f55c4"]

That is a list of id codes sent from the API to me. However it is all one continuous string.

How would I go about converting this into a list?

I figure what I need to do is remove firstly the ['s and then seperate each one from each other. I'm not too sure how to go about it and have searched the internet for a solution but haven't found one.

(I am using C# btw, and heard that lists were better than arrays for this particular thing. Please do correct me if I'm wrong!)

Thanks!!

So, you receive "c7385f31-2c3e-42ae-aae2-57c5ea66088fe6f8f4db-76c4-43a9-b5d3-5d3be606cabd22a55fa7-bf1f-46d9-9c1e-67336c4f55c4" and you want to split it up in three and store each parts in a list am I right ?

I guess there isn't a character of separation then, but each part seems to have the same number of chars (I didn't count). You should use SubString and add each result to a List

I receive it exactly how I wrote it up there, brackets and commas and all.

Yes I think they are the same length (It would certainly make the job easier if they were!

I'm looking around for ways of getting rid of the ['s , and ,'s right now so that I will receive the result you posted

Thanks for the SubString Idea! Ill check it out :)

Thanks man!

Substring is perfect for what I needed! No need to individually cut any unwanted symbols out either! $$anonymous$$uch $$anonymous$$udos to you :)

EDIT: And just in case you're curious, each string is 346 chars long

Just use String.Split, in combination with Substring to strip the outer characters. Then it doesn't matter if the lengths are the same or not. You don't need a List; an array is fine, which is what Split returns.

 string input = "[\"c7385f31-2c3e-42ae-aae2-57c5ea66088f\", \"e6f8f4db-76c4-43a9-b5d3-5d3be606cabd\", \"22a55fa7-bf1f-46d9-9c1e-67336c4f55c4\"]";
 string[] splitter = {"\", \""};
 string[] idCodes = input.Substring(2, input.Length-4).Split(splitter, System.StringSplitOptions.None);
 
 foreach (var id in idCodes) {
     Debug.Log (id);
 }
