What's 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.

The real difference is something else,
please take a look at the IML code of both options...
x.ToString(); is much more extensible code because the
ToString() is
declared virtual, in a OO world you want to use this one and
not the
static crap on the Convert class.
