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如何獲取電腦中的所有盤符

首先使用 System.IO.DriveInfo.GetDrives()獲取System.IO.DriveInfo，存入ds()

然后遍歷ds，獲取各個(gè)信息部分。

Dim ds() As System.IO.DriveInfo = System.IO.DriveInfo.GetDrives()

For i As Integer = 0 To ds.Length - 1

TextBox1.Text = TextBox1.Text + ds(i).DriveType.ToString + " " '驅(qū)動(dòng)器類型

TextBox1.Text = TextBox1.Text + ds(i).Name + " " '盤符（驅(qū)動(dòng)器名）

TextBox1.Text = TextBox1.Text + ds(i).IsReady.ToString + " " '是否就緒

If ds(i).IsReady = True Then

TextBox1.Text = TextBox1.Text + ds(i).VolumeLabel + " " '卷標(biāo)

TextBox1.Text = TextBox1.Text + ds(i).TotalSize.ToString + " " '驅(qū)動(dòng)器容量

TextBox1.Text = TextBox1.Text + ds(i).TotalFreeSpace.ToString '驅(qū)動(dòng)器可用容量

End If

TextBox1.Text = TextBox1.Text + vbNewLine

Next

vb.net 磁盤文件列表，界面如圖，在.net下如何實(shí)現(xiàn)？

預(yù)先準(zhǔn)備三個(gè)圖標(biāo)文件，用于樹型控件中顯示磁盤符號(hào)和文件夾的圖像之用。

1、窗體上添加控件如下：

組合框控件 ComboBox1，樹型控件 TreeView1，列表框控件 ListBox1，圖像列表控件 ImageList1。

選中TreeView1，設(shè)置其ImageList屬性為ImageList1。

2、設(shè)置屬性

選中圖像列表控件 ImageList1，在屬性窗口里，選中屬性Images，單擊三個(gè)小點(diǎn)按鈕，出現(xiàn)圖像集合編輯器窗口，單擊[添加按鈕]，一一把準(zhǔn)備好的圖標(biāo)文件進(jìn)行添加，注意先后次序，如果不符合要求可以通過上下移動(dòng)按鈕重新改變次序。完成后單擊[確定]。

運(yùn)行圖如下：
