Difference between .tostring and convert.tostring

Difference between .tostring and convert.tostring

int i= 0;
MessageBox.Show(i.ToString());
MessageBox.Show(Convert.ToString(i));

We can convert the integer i using i.ToString () or Convert.ToString. So what’s the difference?

The basic difference between them is the Convert function handles NULLS while i.ToString ()does not; it will throw a NULL reference exception error. So as good coding practice using convert is always safe.
