Please help me with the task: Diskspace calculator

Hello, I’m working on this task:

Your next task is to calculate the total amount of space that files occupy on a hard drive.
First, read an integer from the console that represents the total number of files. Then, read a series of numbers that represent the size of each file. Write a program that asks the user to input size of each of these files using the phrase: “Input size of {number} file:”. number represents the order of the files, starting with 1 and incrementing for each file. Finally, find the sum of all of the file sizes and output this result in the following format: “Total disk space is {sum} bytes.” For example:
Input size of 1 file:
Input size of 2 file:
Input size of 3 file:
Total disk space is 21 bytes.

Here is my code:

namespace ForLoops
   class DiskSpace
       static void Main(string[] args)
           string sentence= "Input size of {number} file:";
           int sum = 0;
           int count= int.Parse(Console.ReadLine());
           for(int i = 0; i < count; i++)
               string number=Console.ReadLine();
                sum = sum + int.Parse(Console.ReadLine());
           Console.WriteLine($"Total disk space is {sum} bytes.");

Can anyone please help me to solve it?
