Try/catch block...

I found this in one of my old codes:
public string ReadFile(string filename)
{
try
{
return File.ReadAllText(filename);
}
catch
{
return File.ReadAllText(filename);
}
}:doh:

Mmmm... you seem determined to read that file, is it important?

No. The reading of the file isn't important. That's a code from 2 years ago. Now, I know how I can read files!

Really? :omg: Which value would expect to be returned here?
try
{
return 1;
}
catch
{
return 2;
}
finally
{
return 42;
}I think the C# compiler is doing the right thing. Either the
returnin thefinallyblock is ignored, in which case it shouldn't be allowed, or it replaces any value returned from thetryorcatchblocks, which is just confusing.

I'd do it three times, because three is the magic number:
public string ReadFile(string filename)
{
try
{
return File.ReadAllText(filename);
}
catch
{
return File.ReadAllText(filename);
}
finally
{
return File.ReadAllText(filename);
}
}Quitter - use recursion!
public string ReadFile(string filename)
{
try
{
return File.ReadAllText(filename);
}
catch
{
return ReadFile(filename);
}
}Life is like a s**t sandwich; the more bread you have, the less s**t you eat.

}Maybe we need a more flippant programming language, for those of us who think like this:
try
{
// something
}
ifatfirstyoudontsucceed
{
// try again
}
thirdtimelucky
{
// and again
}
giveup // synonym for catch
{
// error handling
}
finally
{
// tidying up

You would be more likely to get that right if you added commentary: try { return 1; // Genesis } catch { return 22; // Joseph Heller ] finally { return 42; // Douglas Adams }

Oh yes you can do so. But there is a catch - it's "catch 22". Why did it take me so long to see it?

If that's C#, it won't compile; you'll get a "Control cannot leave the body of a finally clause" compiler error.

I had to play around. You can throw an error in the try/catch/finally segments and it will compile. Since I didn't enclose the routine in a try catch, the finally segment did blow up with an unhandled exception. Then I did put it in that logic:
try { int junk = trycat(); } catch (Exception ex) { Console.WriteLine("caught exception {0}", ex.Message); Console.ReadKey(); }...
static int trycat() { try { throw (new Exception("Throwing an exception in try block")); } catch { throw (new Exception("Throwing an exception in catch block")); } finally { throw (new Exception("Throwing an exception in finally block")); } return 1; } -

It sure is! Monty Python : First shalt thou take out the Holy Pin. Then, shalt thou count to three, no more, no less. Three shalt be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, nor either count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in my sight, shall snuff it."
