VB.NET注册表项不存在.NET Win7 x64 [英] VB.NET Registry Key Does Not Exist .NET Win7 x64

问题描述

Public Function sequence() As Byte()
        Dim r As RegistryKey
        Dim return_value As Byte()
        r = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine,_       
        RegistryView.Registry64)
        r.OpenSubKey("SOFTWARE\Microsoft\Windows NT\CurrentVersion",_
        False,_
        Security.AccessControl.RegistryRights.QueryValues)
        return_value = r.GetValue("DigitalProductID", {})
        Return return_value
    End Function

为什么上面的代码返回NULL/值不存在?我曾在WMI编程中尝试过Impersonate等.

我要做的就是在Visual Basic Express 2010中将Digital Product ID作为Byte()数组返回给我(AnyCPU编译.我打算将其添加到DLL).在x86 Windows环境中，这当然很简单.

任何帮助将是巨大的.如果您可以使用C#进行操作，那么我总是可以将其转换为VB.NET

这是我所做的.

Why does the above code return NULL/Value does not exist? I have tried Impersonate etc.. in WMI programming.

All I would like to do is get the Digital Product ID return to me as a Byte() array in Visual Basic Express 2010 (AnyCPU compile. As I intend to add this to a DLL). This is of course simple in a x86 Windows enviroment.

Any help would be great. If you can do it in C# then I can always convert it over to VB.NET

Here is what I have Done.

Google for over 2 days.
WMI Impersonate (With the Set oReg, VBE 2010 freaks and removes the SET)
Setting Secuitry Permissions
Changing registry view to Default/32 and 64.

我完全不知所措.因此，任何帮助都会很棒.

干杯

I am at a complete loss. So any help would be great.

Cheers

推荐答案

尝试以下代码:

Try the following code:

const string queryString = "SELECT SerialNumber FROM Win32_OperatingSystem";

string productId = (from ManagementObject managementObject in new ManagementObjectSearcher(queryString).Get()
                    from PropertyData propertyData in managementObject.Properties
                    where propertyData.Name == "SerialNumber"
                    select (string)propertyData.Value).FirstOrDefault();

Console.WriteLine(productId);
