C# – Understanding Exception Handling

Wrap try …… catch around code:

• That you are calling into you did not write
• Code that accesses external recources
• Code that accepts input from outer sources

try{

}catch(SpecificException ex){
//catch more specific exceptions first
//more general list
}catch(Exception ex){
//log it
//swallow it
//re-throw it
}finally{
//optional...clean up
}
