Hi all, I would like to do the following:
Here is what I have:

C#

ArrayList List = new Arraylist

List[0] = {string[2]}
List[1] = {string[2]}
etc

If you select List[0] you get [0] = "Hello"
                              [1] "guys"

and if you select[1] you get [0] = "how"
                             [1] = "are you?"

How would I extract the data and write a text file to read:

Hello guys. How are you?

Thanks in advance

You could use logic as below.
This is only pseudocode and you may need to typecase objects into strings etc as required (based on your implementation.

foreach(Array objArr in List)
{
   string strFinal=string.Empty;
   foreach(string strText in objArr)
   {
      strFinal += strText;
   }
   WriteTofile(strFinal); //This adds this text to a text file
}

Also, logic to write to a file needs to be implemented as required.

Thanks for the snippet. For the strFinal there is no space between the values?

Well, add space to each element if you want, of '\n' or "\r\n", whatever, what's the big difference?

This is wonderful!

I answered your last question Extracting data from an array.............................................................................[^].

I advised not to use ArrayList (but to use generic List) and your arrays of the size of two, because your intended type was semantically sound, so you should have used a structure with two fields, properly named. You accepted my answer! Now, you repeat exact same "data design" only instead of double[2] you now use string[2]. Let me inform you, that your approach makes no sense, and the change in type means answer.

Your Question is different, and you got correct Answer, but no Answer will really help you if you keep repeating your old mistakes again and again. I don't know what to say… Well, read some manual not just to the point where arrays are explained, but overview structures, classes, generics, members, methods, loops, calls, look at good code samples—

Good luck,
