Try/catch block...

You don't. You throw a

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

It lacks a

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

That would compile on java, I think.
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.

Oh I wasn't saying it should be allowed, but I think it is.

FTSOTR, that does compile in Java (with a little syntactic fix) and returns 42.

The funniest of all, is that when I was programming that, that I didn't know why I got an error sometimes...

Maybe the file was in use :laugh:

When I was programming that, I thought: "It's in a catch block, then it can't throw an error!" X|

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);
}
}Sigh.
public string ReadFile(string filename)
{
string contents = null;
try
{
contents = File.ReadAllText(filename);
}
catch
{
contents = File.ReadAllText(filename);
}
finally
{
contents = File.ReadAllText(filename);
}
return contents;
}Okay. Everybody happy now?

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!

}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?
