VB.NET獲取硬盤信息的幾種方法

strResult += 磁盤類型: System.Convert.ToInt16(disk(DriveType).ToString())End IfMsgBox(strResult)NextEnd Sub總結(jié)：在VB.NET中，用API函數(shù)可以獲取硬盤信息。原來(lái)熟悉API函數(shù)VB6程序員，可以對(duì)API函數(shù)聲明進(jìn)行適當(dāng)?shù)母暮?，進(jìn)行調(diào)用。利用FSO（文件系統(tǒng)對(duì)象）的Scrrun.DLL，也可以獲得磁盤信息。在.net Framwork中，利用WMI可以獲取更多的關(guān)于機(jī)器硬件的詳細(xì)信息（參考System.Management命名空間）。

VB.NET, 變量“ID”在封閉塊塊中隱藏變量

封閉塊中的變量名與塊外變量重名了。

舉例說(shuō)明

...

dim i as byte,a as byte

for i=0 to 10

...

dim a as byte

...

next

...

在FOR循環(huán)中定義了一個(gè)變量A，但是A已經(jīng)在同一過(guò)程里面定義過(guò)了，這時(shí)FOR循環(huán)里面的A會(huì)提示“變量“A”在封閉塊塊中隱藏變量”

你可以在提示出錯(cuò)的地方往前找，看同一過(guò)程里面定義重復(fù)的變量然后改名
