I am trying to add values to an array and then return the whole array after 10 increments.
public int[] multi(int x)
{
int[] array = new int[10];
for (int i = 1; i < array.Length; i++)
{
array[i] = x;
x += x;
}
return array;
}
When i call the method, however, it simply returns System.Int32[], instead of (in this case) 5, 10, 15, 20 etc.
int[] result = lab.multi(5);
Console.WriteLine(result);
All help appreciated!
Function Console.WriteLine calls ToString() on the object, so for reference types it simply prints the type name, which in your case is System.Int32[].
If you want to print integer array you can use function string.Join:
int[] result = lab.multi(5);
Console.WriteLine(string.Join(", ", result));
Console.WriteLine doesn't have an overload for int[], so it's using the object overload which calls the ToString() method. ToString on int[] prints out System.Int32[].
You need to loop through and print out each item.
foreach(var item in result)
{
Console.WriteLine(item);
}
.ToString()defined inObject(from which everything derives in .NET) returns the type - in this caseSystem.Int32[](i.e., an array ofInt32).Console.WriteLine()callsToString()on the object. You need to loop through the array to print out the element values.
