Regedit返回值为null

Question

有人帮我。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

你需要替换：

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

使用

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