c# - Catching an exception -

i'm getting exception thrown , message gives value not fall within expected range. i'm trying right piece of code grab exception , suppress - know issue - trying pull record list using id doesn't exist.

any ideas how go catching this?

to suppress exception need this

try {      // code may throw exception. } catch (exception ex) // better use more specific exception class {     // nothing - suppresses exception.      // if want additional checking may continue exception     // stack use "throw" on own - compiled cil/msil's     // "rethrow" , doesn't drop of information     // go if did "throw ex" } 

that's there suppressing exception.

for sanity of have maintain code (or in 6 months time when you've forgotten specifics of why did this), comment why suppressing exception. if see code suppresses exception want know why.
