c# - Is there a reason to throw an exception twice? -

debugging production code came across had not seen before , not aware of valid purpose. in several methods of 1 of our controllers have try-catch blocks. interesting part there 2 throw statements in 1 of catches.

is there reason have 2 throw statements? if so, in circumstance(s) make sense?

        try         {            //statements         }         catch (soapexception se)         {             //log statement             return null;         }         catch (exception ex)         {             //log statement             throw;             throw;         } 

no there no reason throw twice. second throw never reached.

it similar having

public int getnumber() {     return 1;     return 2; // never reached } 

update

resharper great tool check things this.

in case grey out second throw , tell unreachable.
