Default casting data type

Hi

Could anyone help to explain to me the following question. If I have an object and I want to cast it to string type. What is the different between these 2 codes:

         string temp = (string)anObj;
                    VS
         string temp = anObj.ToString();

OK here is my answer, it wont be as exact but its my stab at it..


string temp = (string)anOBj;

This one uses a explict type conversion called a cast to convert the object into a string..

temp will point to a string object....

second one

string temp = anObj.ToString();
here you are calling the ToString method, which is inherited....
it will force the object anOBj to be described as a sting.. that will be set to temp..... this doesnt create a refernce pointer to it.... as far as i knows... ofcourse i am looking for corrections here ....

Larry.
