/checked (Check Integer Arithmetic) (C# Compiler Options)
The /checked option specifies whether an integer arithmetic statement that is not in the scope of the checked or unchecked keywords and that results in a value outside the range of the data type will cause a run-time exception.
/checked[+ | <U>-</U>]
An integer arithmetic statement that is in the scope of the checked or unchecked keywords is not subject to the effect of the /checked option.
If an integer arithmetic statement that is not in the scope of the checked or unchecked keywords results in a value outside the range of the data type, and /checked+ (/checked) is used in the compilation, then that statement will cause an exception at run time. If /checked- is used in the compilation, then that statement will not cause an exception at run time.
The default value for this option is /checked-, so you can get the same effect by simply omitting the option altogether. One scenario for using /checked- is in building large applications: sometimes automated tools are used to build such applications, and the tools might automatically set /checked to +: in this situation, you can override the global default by specifying /checked-.
