What is difference betweeb .ToString() and Convert.ToString()?

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

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.
