what is the difference between the two forms of converting to integer
from string

string strVal = "10";

Convert.ToInt32(strVal);

Int32.Parse(strVal);

which method is more efficient in terms of performance?

Convert.ToInt32 returns 0 if you pass it null. Int32.Parse will throw
an exception.

The difference is trivial. You should pick based on the semantics you
want.
 
int.Parse() applies only to strings, while Convert.ToInt32() can
convert from any type.

Well, Conver.ToInt32 calls int.Parse at the end. It totally depends
what you want to use and ofcourse Convert will give you more options.
