为什么这"最后"执行？ [英] Why does this "finally" execute?

问题描述

如果您运行下面的代码终于每次调用跳转后实际执行的：

If you run the code below it actually executes the finally after every call to the goto:

    int i = 0;
Found:
    i++;
    try
    {
        throw new Exception();
    }
    catch (Exception)
    {
        goto Found;
    }
    finally
    {
        Console.Write("{0}\t", i);
    }

为什么？

Why?

推荐答案

为什么你期望它没有执行？

Why do you expect it to not execute?

如果你的try / catch / finally或try / finally块，执行finally代码<击>无论你可能有什么样的代码在try或catch块的大部分时间的。

If you have try/catch/finally or try/finally block, finally block executes no matter what code you may have in the try or catch block most of the time.

相反goto语句，可以考虑回归。

Instead of goto, consider 'return'.

//imagine this try/catch/finally block is inside a function with return type of bool. 
try
{
    throw new Exception();
}
catch (Exception)
{
    return false; //Let's say you put a return here, finally block still executes.
}
finally
{
    Console.WriteLine("I am in finally!");
}
