C# Programming/Keywords/unchecked

The unchecked keyword prevents overflow-checking when doing integer arithmetics. It may be used as an operator on a single expression or as a statement on a whole block of code.

intx,y,z;
x=1222111000;
y=1222111000;
// used as an operator
z=unchecked(x*y);
// used as a statement
unchecked{
z=x*y;
x=z*z;
}
