Difference between type casting and parsing?

Question

What is the big difference between parsing and typing? I am trying to use type casting to a string and this gives me an error.

Something like that:

string str = "10";
int i = (int) str;

Answer 1

In order to work with a type, types must be compatible:

object str = 10;
int i = (int) str;

An analysis is a conversion between different types:

string str = "10";
int i = int.Parse(str);

Answer 2

Casting works when objects have part of the inheritance. But in your case

int i = (int) str;

. /losen .NET.

Int32.Parse(...
