Question

I am trying to call these functions to get rid of stuff I don t need, but my code seems to be defeating me in what I am begining to perceive to be a vain struggle. I have tried multiple ways to solve these last two errors, but the IEnumerator is giving me wild cards. errors are on the lines : if (enumerator2 is IDisposable) and if (enumerator is IDisposable)

        try
        {
            enumerator = matchs.GetEnumerator();
            while (enumerator.MoveNext())
            {
                IEnumerator enumerator2;
                Match current = (Match) enumerator.Current;
                num = 0;
                try
                {
                    enumerator2 = current.Groups.GetEnumerator();
                    while (enumerator2.MoveNext())
                    {
                        Group group = (Group) enumerator2.Current;
                        strArray[num, num3] = group.Value;
                        num++;
                    }
                }
                finally
                {
                    if (enumerator2 is IDisposable)
                    {
                        (enumerator2 as IDisposable).Dispose();
                    }
                }
                if (num2 < num3)
                {
                    num2 = num3;
                }
                num3++;
            }
        }
        finally
        {
            if (enumerator is IDisposable)
            {
                (enumerator as IDisposable).Dispose();
            }
        }
        strArray[num, 0] = Conversions.ToString((int) (num2 + 1));
        return strArray;
    }

Answer 1

正如其他人所指出的，您应该使用foreach循环。

但是，出现该错误的原因是，当在finally块中使用枚举器2时，编译器无法知道它被设置为某个值（因为在某些特殊情况下可能不会这样）。您可以按原样修复代码，方法是：

IEnumerator enumerator2 = null;
Match current = ...

Answer 2

使用for each循环，而不是while循环。如果需要，它将为您调用Dispose。
