Bipul tiwari · Answer

Convert.ToString() handles null value , while ToString() does not. Example: Object mObj = null; String mValue1 = mObj.ToString(); //throws Null reference exception String mValue2 = Convert.ToString(mObj); //returns NULL

Hello I think there are not so many difference between toString() and convert.toString() But main difference that i have observed is : toString() : Can not allow null values and throws exception convert.toString() : Empty value can be accepted thus exception will not be thrown Thats what i know For more reference you can go through : https://social.msdn.microsoft.com/Forums/en-US/bf118337-6dbd-4edd-9147-fbbcba7ce6c5/what-is-the-difference-between-converttostring-and-tostring?forum=csharpgeneral http://www.c-sharpcorner.com/blogs/difference-between-tostring-and-converttostring-in-c-sharp1 http://www.aspdotnet-suresh.com/2012/10/c-difference-between-converttostring.html I hope now you solved your doubt Thanks

Its really a good practice to use Convert.Tostring as it handles null value exception.On the other hand .toString() does throws an exception which we need to handle in the catch block of our C# code.

Hi Manish, when you convert a value into string you can use .ToString or Convert.Tostring. .Tostring given you null reference exception when value is null where as Convert.Tostring won't give you any exception.

Example string str; object i = null; str = i.ToString(); //Returns a null reference exception for str. -------------------------------------------------------------------------------------- string str; object i = null; str = Convert.ToString(i); //Returns an empty string for str and does not throw an exception. If you dont The basic difference between them is “Convert.ToString(variable)” handles NULL values even if variable value become null but “variable.ToString()” will not handle NULL values it will throw a NULL reference exception error. So as a good coding practice using “convert” is always safe.

Convert.ToString handles null while ToString doesn’t and throws a NULL reference exception.
