Checked and Unchecked C# with Example



Checked and Unchecked C# with Example

C# statements executes in either checked or unchecked context. In a checked context, arithmetic overflow raises an 
exception. In an unchecked context, arithmetic overflow is ignored and the result is truncated. 
short m = 32767; 
short n = 32767; 
int result1 = checked((short)(m + n)); //will   throw   an   OverflowException 
int result2 = unchecked((short)(m + n)); // will return -2 
If neither of these are specified then the default context will rely on other factors, such as compiler options.
