默认情况下Powershell大量的输出结果是包括数字的字符串，但是有些时候我们想将其输出结果变为纯数字，以便将结果输出到其它地方（比如输出到ZABBIX可实现一些图表的绘制）。
举例说明：
1 默认情况下查看Exchange 某个数据库的大小
[PS] C:\MailBoxOperate\Function>Get-MailboxDatabase BOSS* -status |%{$_.databasesize}
56.13 GB (60,272,738,304 bytes)
2如果我们希望将结果只显示为56.13怎么办？
1)首先将上述命令替换为一个函数
$Database=Get-MailboxDatabase BOSS* -status |%{$_.databasesize}
2)查看一下这个函数的属性
C:\MailBoxOperate\Function>$Database |gm
TypeName: Microsoft.Exchange.Data.ByteQuantifiedSize
Name MemberType Definition
---- ---------- ----------
CompareTo Method int CompareTo(Microsoft.Exchange.Data.ByteQuantifiedSize other)
Equals Method bool Equals(System.Object obj), bool Equals(Microsoft.Exchange.Data.ByteQuantifiedSize other)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
RoundUpToUnit Method System.UInt64 RoundUpToUnit(Microsoft.Exchange.Data.ByteQuantifiedSize+Quantifier quantifier)
ToBytes Method System.UInt64 ToBytes()
ToGB Method System.UInt64 ToGB()

ToTB Method System.UInt64 ToTB()
3) 数据处理过程：
将结果输出为ToGB
C:\MailBoxOperate\Function>$Database.ToGB()
56
当然也可输入出ToBytes
C:\MailBoxOperate\Function>$Database.Tobytes()
