convert.ToString() vs ToString() in C#

Lets understand the difference via this example:

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
