[p]當(dāng)您使用filesystemobject對(duì)象獲得某個(gè)目錄下的文件列表的時(shí)候，你有沒(méi)有發(fā)現(xiàn)無(wú)法控制它們的排序方式，比如按照名字排序，按照擴(kuò)展名排序，按照文件大小排序等等，讓我們?cè)囍脭?shù)組給它們排排序兒。[br]如果您想通過(guò)名字排序，那將是非常簡(jiǎn)單的，但是假如你想通過(guò)文件大小或者文件創(chuàng)立時(shí)間等等來(lái)排序的時(shí)候，那么將有點(diǎn)麻煩。我們將通過(guò)二維數(shù)組做到這一點(diǎn)。[br]下面的代碼演示了如何通過(guò)選擇排序方式達(dá)到的我們目的，單擊排序，點(diǎn)兩次就反著排了。[/p]
[p][br][br][br][/p]
[p][/p]
[p]<%[br]' 設(shè)定一個(gè)演示目錄，：）[/p]
[p]const directory = "/" [/p]
[p]' 用常數(shù)定義排序方式[br]const file_name = 0 '按照名字排序……依次類推[br]const file_ext = 1[br]const file_type = 2[br]const file_size = 3[br]const file_created = 4[br]const file_modified = 5[br]const file_accessed = 6[/p]
[p]'獲得 排序命令，默認(rèn)為按照名字排序[/p]
[p]req = request("sortby")[br]if len(req) < 1 then sortby = 0 else sortby = cint(req)[br]req = request("priorsort")[br]if len(req) < 1 then priorsort = -1 else priorsort = cint(req)[/p]
[p]'設(shè)置倒序[br]if sortby = priorsort then[br]reverse = true[br]priorsort = -1[br]else[br]reverse = false[br]priorsort = sortby[br]end if[/p]
[p]' 接下來(lái)開(kāi)始我們真正的代碼了。。。[/p]
[p]path = server.mappath( directory )[/p]
[p]set fso = createobject("scripting.filesystemobject")[br]set thecurrentfolder = fso.getfolder( path ) [br]set curfiles = thecurrentfolder.files [/p]

[p]dim thefiles( )[br]redim thefiles( 500 ) ' 我隨便定的一個(gè)大小[br]currentslot = -1 ' start before first slot[/p]

[p]' 現(xiàn)在都在數(shù)組里了，開(kāi)始下一步[/p]
[p][br]filecount = currentslot ' 文件數(shù)量[br]redim preserve thefiles( currentslot ) [/p]
[p]' 排序[br]' (8 表示 string)[/p]
[p]if vartype( thefiles( 0 )( sortby ) ) = 8 then [br]if reverse then kind = 1 else kind = 2 ' 給字符排序[br]else[br]if reverse then kind = 3 else kind = 4 '數(shù)字、時(shí)間。。。[br]end if[/p]
