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
