Regedit返回值null

Question

有人帮助我。 为什么这段代码不能正常工作。 仍然返回null。

RegistryKey hklm = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);

RegistryKey rk = hklm.OpenSubKey(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQLServer\SuperSocketNetLib\Tcp\IPAll",RegistryRights.ReadKey);

string valueName = "TcpPort";

Answer 1

您需要替换：

hklm.OpenSubKey(@"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQLServer\SuperSocketNetLib\Tcp\IPAll",RegistryRights.ReadKey);

与

hklm.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQLServer\SuperSocketNetLib\Tcp\IPAll",RegistryRights.ReadKey);
