Error: cannot implicitly convert type void to microsoft.win32.registrykey

Code:

using Microsft.Win32;
RegistryKey key = Registry.CurrentUser.OpenSubKey(@"Sofware",true).DeleteSubKey("TEST");

But for some reason this code works:

using Microsft.Win32;
RegistryKey key1 = Registry.CurrentUser.OpenSubKey(@"Sofware", true).CreateSubKey("TEST");

CodePudding user response：

Looking at the signature of DeleteSubKey here It says it is void, hence it returns nothing and cannot be assigned to RegistryKey. Call the function without using its return value
