What is the difference between Convert.ToString and .ToString() method ?

Just to give an understanding of what the above question means seethe below code.

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 “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.
