It is true that conver.tostring return zero if the inputed string is null but .to string it that case raise exception.But if you sure that the inputed string is not null,then it is better to use .tostring method instead of convert.tostring

Hello

Convert.toString(.........) handles null while i.tostring() does not handles null.

Thnx

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 “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.
