How to Convert a String in a FOR Loop

Question

Hallo Team,

 

I have a question for a web project. I need some tips to develop it.

I have to develop a printer program in C#, which GUI will be developped with JQuery.

For the printer program I opened a socket connection. 

Here some requisitions of the project:

 

I need to work on a ZPL string (because the printer works on a ZPL code), thats why I have: 

 

string ZPLString = "^FT70,230^A0N,60,60^FD01 0001 0001 0011^FS"

 

 and I have to build a counter for this piece of string 0011 which starts counting from 1 to 11 

 

that's why I set a variable  

 

string objectNumber = "0011";

 

 For the Counter I wrote a for loop

 

for (int i = 1; i < BranchOffice.StartObjectNumber; i++)

{

        byte[] sendBytes = Encoding.GetEncoding("Cp850").GetBytes(objectNumber);

        stream.Write(sendBytes, 0, sendBytes.Length);

}

 

we all know that in a for-loop thare are only conditions in int data type

but I actually need the string "0011" to let run through from 1 to 11 so that the program can print more tickets at the same time If I select for example 001 to 004 on the UI (because the User has got this printer program on its web portal).

 

Thats's the reason why I thought to convert the string like that:

 

int x = 0;

string objectNumber = "0001";

Int32.TryParse(objectNumber, out x);

 

so that I can count from 1 to 11 in the for loop but it doesnt work.

It prints only one ticket. 

 

Now my questions are:

 

1) how shall I use the converted string in this for-loop? 

 

2) Shall I  better implement the for-loop in JavaScript/JQuery rather then in C#?

 

I hope you can help me. I'm a beginner Software Developer and I still don't know which the best solution could be.

 

Thank you in advance.

Have a nice start in the week.
