1回顶部 1、用API函数GetDiskFreeSpaceEx获取磁盘空间Private Declare Function GetDiskFreeSpaceEx Lib "kernel32" Alias "GetDiskFreeSpaceExA" _ (ByVal lpDirectoryName As String, ByRef lpFreeBytesAvailableToCaller As Long, _ ByRef lpTotalNumberOfBytes As Long, ByRef lpTotalNumberOfFreeBytes As Long) As Long Private Sub btnDisk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisk.Click Dim BytesFreeToCalller As Long, TotalBytes As Long Dim TotalFreeBytes As Long, TotalBytesUsed As Long Dim strResult As String Const RootPathName = "C:\" Call GetDiskFreeSpaceEx(RootPathName, BytesFreeToCalller, TotalBytes, TotalFreeBytes) strResult = " Drive " & "C:\" & vbCrLf strResult += "磁盘容量(MB):" & Format(CDbl((TotalBytes / 1024) / 1024), "###,###,##0.00") & vbCrLf strResult += "可用空间(MB):" & Format(CDbl((TotalFreeBytes / 1024) / 1024), "###,###,##0.00") & vbCrLf strResult += "已用空间(MB):" & Format(CDbl(((TotalBytes - TotalFreeBytes) / 1024) / 1024), "###,###,##0.00") & vbCrLf MsgBox(strResult) End Sub 2、用FSO(文件系统对象模型)实现 FSO对象模型包含在SCRIPTING类型库(SCRRUN.DLL)中。调用方法如下： 在项目菜单中选择引用，在COM中选择Microsoft Scripting Runtime 2回顶部 在代码最顶端添加Imports Scripting，在按钮的单击事件中加入以下代码： Imports Scripting Private Sub btnFso_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFso.Click Dim Fso As New FileSystemObject Dim drvDisk As Drive, strResult As String drvDisk = Fso.GetDrive("C:\") strResult = "Drive " & "C:\" & vbCrLf strResult += "磁盘卷标:" & drvDisk.VolumeName & vbCrLf strResult += "磁盘序列号:" & drvDisk.SerialNumber & vbCrLf strResult += "磁盘类型:" & drvDisk.DriveType & vbCrLf strResult += "文件系统:" & drvDisk.FileSystem & vbCrLf strResult += "磁盘容量(G): " & FormatNumber(((drvDisk.TotalSize / 1024) / 1024) / 1024, 2, , , Microsoft.VisualBasic.TriState.True) & vbCrLf strResult += "可用空间(G): " & FormatNumber(((drvDisk.FreeSpace / 1024) / 1024) / 1024, 2, , , Microsoft.VisualBasic.TriState.True) & vbCrLf strResult += "已用空间(G):" & FormatNumber(((((drvDisk.TotalSize - drvDisk.FreeSpace) / 1024) / 1024) / 1024), 2, , , Microsoft.VisualBasic.TriState.True) MsgBox(strResult) End Sub 3、用API函数GetVolumeInformation获取逻辑盘序列号 Private Declare Function GetVolumeInformation Lib "kernel32" Alias "GetVolumeInformationA" _ (ByVal lpRootPathName As String, ByVal lpVolumeNameBuffer As String, ByVal _ nVolumeNameSize As Integer, ByRef lpVolumeSerialNumber As Long, _ ByVal lpMaximumComponentLength As Integer, ByVal lpFileSystemFlags As Integer, ByVal _ lpFileSystemNameBuffer As String, ByVal nFileSystemNameSize As Integer) As Integer 3回顶部 Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim SerialNumber As Long Dim TempStr1 As New String(Chr(0), 255) Dim TempStr2 As New String(Chr(0), 255) Dim TempInt1, TempInt2 As Integer GetVolumeInformation("C:\", TempStr1, 256, SerialNumber, TempInt1, TempInt2, TempStr2, 256) MsgBox("C盘序列号:" & SerialNumber) End Sub 4、利用WMI获取硬盘信息 Windows Management Instrumentation (WMI) 是可伸缩的系统管理结构，它采用一个统一的、基于标准的、可扩展的面向对象接口。WMI 为您提供与系统管理信息和基础 WMI API 交互的标准方法。WMI 主要由系统管理应用程序开发人员和管理员用来访问和操作系统管理信息。 我们需要使用.net Framwork里面System.Management命名空间下提供的类来实现。 Imports System.Management Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim disk As ManagementBaseObject Dim strResult As String Dim diskClass = New ManagementClass("Win32_LogicalDisk") Dim disks As ManagementObjectCollection disks = diskClass.GetInstances() For Each disk In disks strResult = "" strResult += "设备ID:" & disk("DeviceID") & vbCrLf 4回顶部 strResult += "磁盘名称:" & disk("Name") & vbCrLf strResult += "磁盘卷标:" & disk("VolumeName") & vbCrLf If disk("FileSystem") <> "" Then strResult += "文件系统:" & disk("FileSystem") & vbCrLf strResult += "磁盘描述:" & disk("Description") & vbCrLf If System.Convert.ToInt64(disk("Size")) > 0 Then strResult += "磁盘大小:" & System.Convert.ToInt64(disk("Size").ToString()) & vbCrLf strResult += "磁盘类型:" & System.Convert.ToInt16(disk("DriveType").ToString()) End If MsgBox(strResult) Next End Sub 总结：在VB.NET中，用API函数可以获取硬盘信息。原来熟悉API函数VB6程序员，可以对API函数声明进行适当的更改后，进行调用。利用FSO（文件系统对象）的Scrrun.DLL，也可以获得磁盘信息。在.net Framwork中，利用WMI可以获取更多的关于机器硬件的详细信息（参考System.Management命名空间）。 声明：本文版权与解释权归李洪根所有，如需转载，请保留完整的内容及此声明。 QQ: 21177563 MSN: lihonggen@hotmail.com |
