C＃で登録された所有者を取得すると、未知の値が返される

Question

C＃WinFormsアプリケーションでRegisteredOwnerとRegisteredOrganizationの値を取得しようとしていて、デフォルト値を未知数として返しています。

string Owner = ""; 
     string Company = ""; 

     OperatingSystem osInfo = System.Environment.OSVersion; 
     if (osInfo.Platform == PlatformID.Win32Windows) 
     { 
      // Windows 98             
      Owner = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "RegisteredOwner", "Unknown"); 
      Company = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "RegisteredOrganization", "Unknown"); 
     } 
     else if (osInfo.Platform == PlatformID.Win32NT) 
     { 
      // for NT+     
      Owner = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "RegisteredOwner", "Unknown"); 
      Company = (string)Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "RegisteredOrganization", "Unknown");    
      // do you need admin to read? or just write? b/c you need the UAC elevation. so out it on the Save button if it is just save changes, or in manifest.    
     } 

     lblRegOwner.Text = Owner;    
     lblRegOrg.Text = Company; 

同じ結果を持つ管理者としてプログラムを実行しようとしましたが、標準のコマンドプロンプトを使用して、返された値を取得できました。

これを試してみてください：

string Owner = ""; 
string Company = ""; 

OperatingSystem osInfo = System.Environment.OSVersion; 
if (osInfo.Platform == PlatformID.Win32Windows) 
{ 
    // Windows 98             
    Owner = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "RegisteredOwner", "Unknown").ToString(); 
    Company = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "RegisteredOrganization", "Unknown").ToString(); 
} 
else if (osInfo.Platform == PlatformID.Win32NT) 
{ 
    // for NT+     
    RegistryKey localKey; 
    if (Environment.Is64BitOperatingSystem) 
     localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64); 
    else 
     localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32); 

    Owner = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion").GetValue("RegisteredOwner", "Unknown").ToString(); 
    Company = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion").GetValue("RegisteredOrganization", "Unknown").ToString(); 
} 

lblRegOwner.Text = Owner; 
lblRegOrg.Text = Company;
