My C# output is in the form:
Epoch Timestamp1,Cost1,Epoch Timestamp2,Cost2,Epoch Timestamp3,Cost3.
(Costn is the cost for Epoch TImestampn.)
I want to get the cost for each timestamp, in the below manner:
timestamp cost
timestamp cost
..
..
..
I am implementing this in C# in Visual Studio 2017.
How can I implement this? Any ideas please?
Thank you.


Just use Split and a for loop, add pepper and salt to taste
var input = "Epoch Timestamp1,Cost1,Epoch Timestamp2,Cost2,Epoch Timestamp3,Cost3.";
var split = input.Split(',');
var results = new List<string>();
for (int i = 0; i < split.Length; i+=2)
results.Add(split[i] + " " + split[i + 1]);
foreach (var item in results)
Console.WriteLine(item);

My list is:
var list = new List<int>()
{
1, 2, 3, 4
};
Without doing
int sum = list[0]*list[0] + list[1]*list[1] + list[2]*list[2] + list[3]*list[3]

var result = list.Sum(o => o * o);

While the other answers work as well, you should learn how to use a loop. It is a fundamental building block of programming. For example, we can use a foreach loop to iterate over each element in the list. see:
int sum = 0;
foreach (int val in list)
sum += val * val;

Currently, I am trying to convert coffee script from there https://github.com/slang800/instagram-id-to-url-segment to C# but I am unable to convert because I have less exp in coffee script. What I need to do is simple but I am unable to guess the algo. If id is 1038059720608660215 then value should be 5n7dDmhTr3. The complete code of algo is available at github.

Try this
static void Main(string[] args)
{
string[] convert = {
"A","B","C","D","E","F","G","H","I","J",
"K","L","M","N","O","P","Q","R","S","T",
"U","V","W","X","Y","Z","a","b","c","d",
"e","f","g","h","i","j","k","l","m","n",
"o","p","q","r","s","t","u","v","w","x",
"y","z","0","1","2","3","4","5","6","7",
"8","9","-","_"
};
Int64 input = 1038059720608660215;
string output = "";
for (int i = 9; i >= 0; i--)
{
long digit = (input >> (6 * i)) & 0x3F;
output += convert[digit];
}
Console.WriteLine(output);
Console.ReadLine();
}

I have this code that helps me getting information from texts files , the problem is that i cant get to add all the strings founds in the texts files into one int.
in the first Entrada.txt i have a 23 and in the second one i have 45.
How can i add those 2 numbers together?
foreach(var impressora in ListaImp)
{
var Entrada = File.ReadAllText(impressora + #"\Entrada.txt");
MessageBox.Show("Entrada : " + Entrada);
}
Output: 2345.
I want it to be 23 + 45 = 68

You can do this:
int sub = 0;
foreach(var impressora in ListaImp)
{
var Entrada = File.ReadAllText(impressora + #"\Entrada.txt");
sub += int.Parse(Entrada);
}
MessageBox.Show(sub.ToString());

I enter the value in textbox:
1,2,3,4,5,6,7...
How to into to int array or list and show value display ???
And stop when a user enters the wrong consecutive 3 times or total error of 5

//textbox is your textbox controls' name
string[] content = textbox.Text.Split(',');
//use linq convert stringp[] to int[]
int[] nums = (from num in content
select int.Parse(num)).ToArray();

I don't understand the last part of your question (the bit about stopping when a user enters something wrong... I guess you'd have to define "wrong" in this context). Regardless, the following code should take values entered into a text box (let's call it txtNumbers) and put it in an array of ints.
string[] splitContent = txtNumbers.Text.Split(new char[] { ',' });
int[] nums = new int[splitContent.Length];
for (int i = 0; i < splitContent.Length; i++)
{
nums[i] = Int32.Parse(splitContent[i]);
}

Is it possible in c# to do math with file names that contain numbers? (i.e. change
file name : "c:\123.img" to "c:\127.img"?

This should be enough to get you started:
var files = Directory.GetFiles(path);
foreach (var f in files)
{
var info = new FileInfo(f);
var name = info.Name.Split('.')[0];
var extension = info.Name.Split('.')[1];
int i;
if (int.TryParse(name, out i))
{
File.Move(info.FullName, string.Format(#"{0}\{1}.{2}", path, i + 5, extension));
}
}
