What is the difference between int.Parse() and Convert.toInt32()...

I got this example through net..hope it helps you.
Both(Convert.ToInt32 and int.Parse) will return the same
result in
most of the cases. But null is handled differently.
Consider the following example…

string strCount="32";
int count1 = Convert.ToInt32(strCount);
int count2 = int.Parse(strCount);

If you print the result it will be same ie 32.

If suppose the string is the null (see the example below),
Convert.ToInt32 will return zero.
but the int.Parse will throw ArgumentNullException error.

string strCount=null;
int count1 = Convert.ToInt32(strCount);
int count2 = int.Parse(strCount); // Error
