By adding two-byte values, CLR assumes the sum may be bigger than a type of byte, so it declares the sum variable to int by default. And C is already declared to the type of byte, the explicit conversion is needed.

Because the arithmetic expression on the right-hand side of the assignment operator evaluates to int by default.

For short and byte types compiler asks for explicit conversion.
The reason is its rule but with common sense that any mathematical calculations can go beyond byte and short types.

Can any one have to explain this question in detail?

Value type means int so why not type cast int. Please any one clarify my doubt?

This is an example of Type Promotion, viz: All byte and short are promoted to int.
The two correct expressions should be:
1. int c = a+b // If c wasn't declared byte.
2. c = (byte) (a+b) // The question asked.
The two correct expressions should be:
1. int c = a+b // If c wasn't declared byte.
2. c = (byte) (a+b) // The question asked.

byte a = 11, b = 22, c;
Here 'a' is declared as byte and 'b' is declared as byte then 'c' is also declared as a byte.
Then why do we need byte conversion for 'c'?
