Answer 1

At first glance, hoping no syntax errors.
Your do while consumes all inputs.. How then for loop read input?

Answer 2

/*reduced to work as it takes numbers of elements to read in first line.. next n lines are input data to array..
*/

using System;

namespace Sololearn
{
class Program
{
static void Main(string[] args)
{
int sum=0;
int n = Convert.ToInt32( Console.ReadLine() );

int[] row = new int[n];

for(int i=0;i<n;i++)
{
row[i]= Convert.ToInt32( Console.ReadLine() );
sum=sum+row[i];
}

Console.WriteLine(sum);
}
}
}
