格式化文件大小 (C# 和 PHP)

发现了一个格式化文件大小的方法, 很帅, 很简洁, 尤其是 PHP 版的, 只需要 2 行代码.

PHP 版:

 

function format($size)
{
$sizetext=array(" B"," KB"," MB"," GB"," TB"," PB"," EB"," ZB"," YB");
returnround($size/pow(1024,($i=floor(log($size,1024)))),2).$sizetext[$i];
}

 

C# 版:

 

publicstring formatSize(long size)
{
if (size ==0) return"0";
string[] sizetext =newstring[] { " B", " KB", " MB", " GB", " TB", " PB" };
int i = (int)Math.Floor(Math.Log(size, 1024));
return Math.Round(size / Math.Pow(1024, i), 2).ToString() + sizetext[i];
}
