try-catch block

Question

I have a class with different methods doing the same thing reading a file. I want to use try-catch block for exception handling. I want to ask if there is any way so that all methods will go inside a single try block as every method will give same exception "file not found"..

Answer 1

My preferred way of handling that would be to call a common method from all of them, so each (individually) looks like:

try {
   // code
} catch(SomeExceptionType ex) {
   DoSomethingAboutThat(ex);
}

However, you can also do it with delegates, i.e.

void Execute(Action action) {
    try {
       // code
    } catch(SomeExceptionType ex) {
       // do something
    }
}

and

Execute(() => {open file});
