bytes/1024 高搭= kb, 戚蚂拿/1024 = mb, /1024 =gb
四舍五入用Math.Round(数字，位数)
如图 我硬盘中有个文件是1.02GB, 1,096,032,256 bytes
1,096,032,256/1024/1024/1024 = 1.020759582519531...
Math.Round(1.020759582519531,2) 得到物枣1.02

有什么证据证明不是除以1024？
KB = B >> 10
MB = KB >> 10 = B >> 20
GB = MB >> 10 = KB >> 20 = B >> 30
计算的区别主要是由于硬件厂商使用1000进制，操作系统使用1024造成的。
