Both(Convert.ToInt32 and int.Parse) will return the same
result in
most of the cases.

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 throw ArgumentNullException error.

and the int.Parse will throw ArgumentNullException error.

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