使用VB.NET,C#或VBScript,如何检查运行IIS 7.x的计算机上是否已安装IIS 6管理兼容性功能及其子功能?
答案 0 :(得分:8)
我使用Registry Workshop的试用版(比较注册表功能)进行了一些测试,发现了以下内容:
如果安装了IIS 7.x,则以下注册表项包含有关已安装子组件的信息:
HKEY_LOCAL_MACHINE \ SOFTWARE \微软\ InetStp \组件
每个已安装的功能都使用值DWORD 0x00000001表示。如果未安装某个功能,则该值将丢失。
对于Web管理工具,值名称如下:
Web Management Tools
IIS 6 Management Compatibility
IIS 6 Management Console (LegacySnapin)
IIS 6 Scripting Tools (LegacyScripts)
IIS 6 WMI Compatibility (WMICompatibility)
IIS Metabase and IIS 6 configuration compatibility (Metabase + ADSICompatibility)
IIS Management Console (ManagementConsole)
IIS Management Scripts and Tools (ManagementScriptingTools)
IIS Management Service (AdminService)
请注意,这些组件名称来自Windows 7安装,可能与Windows Server 2008略有不同,但注册表项应该相同。
本文的注释中提到了其中一些内容: Using Managed Code to Detect if IIS is Installed and ASP/ASP.NET is Registered
可以在此处找到这些和其他子组件的列表: Discover Installed Components

最终代码中的一些核心功能。这不是完整的代码,但对于那些花时间查找各种IIS版本的组件名称的人来说应该足够了:
Function IsIISComponentInstalled(ByVal ComponentName)
Dim result
Dim intProcessorArchitecture
intProcessorArchitecture = GetProcessorArchitectureIIS()
If intProcessorArchitecture = 64 Then
'64-bit system
On Error Resume Next
Err.Clear
result = RegReadDWORD(HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\InetStp\Components", ComponentName, 64)
If Err.Number <> 0 Then
Err.Clear
IsIISComponentInstalled = False
Else
If result = 1 Then
IsIISComponentInstalled = True
Else
IsIISComponentInstalled = False
End If
End If
Else
'32-bit system
If RegReadStringIIS("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp\Components\" & ComponentName) = "1" Then
IsIISComponentInstalled = True
Else
IsIISComponentInstalled = False
End If
End If
End Function
Function GetProcessorArchitectureIIS()
Dim strProcessorArchitecture
Dim oShell
Set oShell = CreateObject("Wscript.Shell")
strProcessorArchitecture = oShell.RegRead("HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\PROCESSOR_ARCHITECTURE")
If strProcessorArchitecture = "x86" Then
GetProcessorArchitectureIIS = 32
Else
If strProcessorArchitecture = "AMD64" Then
GetProcessorArchitectureIIS = 64
Else
GetProcessorArchitectureIIS = 0
End If
End If
End Function
Function RegReadStringIIS(sRegValue)
Set oShell = CreateObject("WScript.Shell")
On Error Resume Next
RegReadStringIIS = oShell.RegRead(sRegValue)
If Err Then
RegReadStringIIS = ""
Err.clear
End If
If VarType(RegReadStringIIS) < vbArray Then
If RegReadStringIIS = sRegValue Then
RegReadStringIIS = ""
End If
End If
On Error Goto 0
End Function
