I know all that you send me but like I said - i don't want to miss something and I asked if anyone is using some ready solutions (also paid) that can do this decoding for me.

I only wanted to show you that EAN13 can also contain weight or price because you wrote that EAN13 contains only article number. My question was about decoding string not only from EAN13 which are the easiest to do - most of all I need help with EAN128, Code128 where are many possibilities and AI.

This's not our standard code - we have to print it because some of our clients need such EAN13 code - this code is printed on label only if our customer wants. Clients send us specification of codes which they want from us. Clients' POS systems reads it correctly. This is just a market need.

I don't know exactly what is the structure of the information because it can be different. For example 1 EAN128 code can contains only article number and batch, another one can contains article number with weight and batch, another can contains article with number of pieces and production date etc. There are many possibilities. AI tells what information this string contains and what I need is good algorithm that search for all possible AI and decode string into separate information. I don't want to miss any possibility.

We are using EAN13 that contains only 13 digits and in this 13 digits is price or weight with article number without any extra 2 or 5 digits - it's always 13 digits EAN13 code.

I don't want to decode image. My application send me as you wrote string readed from barcode image. I want to decode this string into separate information connected with barcodes AI's. I get string like 019123456789012331030605781516120510161128001 and I want to get it into PLU 01 - 1234567890123 then weight 3103 06000 (60,578kg), best before 15 161205 (05.12.2016) and LOT 10 161128001.

I know how barcodes work. I'm working about 12 years with ERP systems that use barcodes. You're right - GS1 it's not a code - it's non-profit organization. I thought about GS1-databar. EAN13 not only provides Article Number - it also can contain weight or price of article. My application send string from barcode scanner and only one think I need is to get this string separated into detailed data for example batch after 10, BBD after 15/17, weight after 310x etc. I know many of AI but I need solution which knows all of possible AI and will search string from barcode and seperate data after AI. I don't want to write it from the beggining because I don't want to miss any AI etc.

I'm writing application in C# (WPF, .net 4.5). I need library for decoding barcodes (EAN128, GS1, code 128, EAN13). Can anyone suggest me ready to use library (free or paid). My scanner connected by USB reads a barcode and sends string od chars (mostly numbers) and I need to decode it to separated PLU, LOT, BBD etc.
