You can use a for or foreach loop, or string.Join So "[" + string.Join(", ", myArray) + "]", or use string interpolation $"[{string.Join(", ", myArray)}]"

idk about string interpolation is it like list comprehension in python

ero•2y ago

No, it's like string interpolation in python f"My value: {myValue}"

Ryan-T1412•2y ago

hmm i got it thx but where is the index numn {0} and why there is a $ symbol

canton7•2y ago

C# uses $"..." for string interpolation, just like python uses f"..." There's no {0} because string interpolation doesn't use {0}

Ryan-T1412•2y ago

so if i type print(myArray) python making this automatically

canton7•2y ago

Indeed, and C# doesn't

cool

// Creating Objects
Problem test1 = new Problem();

var result = test1.ArrayOfMultiples(5,7);
// Printing Variables
Console.WriteLine(result);

// Class
class Problem
{
    // Method 
    public string ArrayOfMultiples(int num, int length)
    {
        int[] myArray = new int[length];
        for( int i = 0; i < length; i++ )
        {
            myArray[i] = (i+1) * num;
            Console.WriteLine(myArray[i]);
        }
        return $"[{string.Join(", ", myArray)}]";
    }
}

            Console.WriteLine(myArray[i]);
        }
        return $"[{string.Join(", ", myArray)}]";
    }
}

which one is the most common

canton7•2y ago

No idea. Use whichever you think is more readable
