int sum=0;

for(int i=0;i<list.Count;i++){

sum+=list[i];

}

return sum;

}

public static void Main (string[] args) {

string val;

List<int> arrList=new List<int>();

for(int i=0;i<10;i++){

Console.Write("Enter Integer: ");

val = Console.ReadLine();

int a = Convert.ToInt32(val);

arrList.Add(a);

}

Console.WriteLine("Entered numbers are: ");

for(int i=0;i<arrList.Count;i++){

Console.WriteLine(arrList[i]+" ");

}

Console.WriteLine("The sum of numbers in List is : {0}",sumOfArrayListNumbers(arrList));

}

}
