Hi Friends
I have a problem with summarizing this statement in 4 lines.
could anyone help me please?

private static string GetSize(long length)
        {
            if (length >= 1024 * 1024 * 1024)
                return string.Format("{0:f2} GB", (double)length / (1024.0 * 1024.0 * 1024.0));
            else if (length >= 1024 * 1024)
                return string.Format("{0:f2} MB", (double)length / (1024.0 * 1024.0));
            else if (length >= 1024)
                return string.Format("{0:f2} KB", (double)length / (1024.0));

            return string.Format("{0} Bytes", length);
        }

推荐答案

我不知道通过概括一下这是什么意思，您可以通过使用减少行数这 "?"操作员，但以可读性/可维护性为代价.例如:

I''m not sure what you mean by summarizing this, you could reduce the lines count by using the "?" operator, but at the expense of readablility / maintainability. For example:

return length >= 1024 * 1024 * 1024 ? string.Format("{0:f2} GB", (double)length / (1024.0 * 1024.0 * 1024.0)) : length >= 1024 * 1024 ? ...

就我个人而言，我会把它留给别人听.

Personally, I would leave it pretty much alone.
