static extern int RegQueryValueEx(
IntPtr hKey,
string lpValueName,

Key Types:
| Type | Value |
| REG_NONE | 0 |
| REG_SZ | 1 |
| REG_EXPAND_SZ | 2 |
| REG_BINARY | 3 |
| REG_DWORD | 4 |
| REG_DWORD_LITTLE_ENDIAN | 4 |
| REG_DWORD_BIG_ENDIAN | 5 |
| REG_LINK | 6 |
| REG_MULTI_SZ | 7 |
User-Defined Types:
None.
Notes:
Managed APIs won't let you get raw REG_EXPAND_SZ values. You'll be forced to use Win32 APIs for this. Also, since .NET won'T give access to the key pointer, you'll have to browse the registry using pInvoke.
Tips & Tricks:
None.
Sample Code:
None.
Alternative Managed API:
namespace Microsoft.Win32;
classes Registery, RegistryKey
