What does ' ' do in Console.Write();

I’m trying to write all the elements of an array and this works ofcourse:

foreach (int i in arr)
{
    Console.Write(i + " ");
}

but this:

foreach (int i in arr)
{
    Console.Write(i + ' ');
}

returns something completely different. Why is that?

Edit:
Let’s say i have this array: [1, 3, 2, 8, 5, 4]. If I use the method with " " it prints just fine. If i use ' ' though it prints this: 333534403736.

>Solution :

Single quote represents a single character with the value ' ' (which is transformed to 32) where as a double quote appends a null terminator '\0' to the end of the string, so " " is actually " \0" and is larger in one byte than the intended size.

So for example, the iterations can be translated to:

1 + 32 // 33
3 + 32 // 35
2 + 32 // 34
8 + 32 // 40
5 + 32 // 37
4 + 32 // 36

Hence, the print will be: 333534403736
