Convert.ToString() vs .ToString()

Hi Ashish,

Convert.ToString() handles null, while ToString() doesn't. So it will throw a NULL reference exception error. So as good coding practice using convert is always safe.

Hi,

If you declare a string variable and don't assign any value in C#. Then by default it take a blank or null value itself . in this case if u use .ToString() method then our program should throw null reference exception. and in Convert.ToString() our program doesn't throw any exception. bcoz by default it takes a blank value instead of null
