C# Count registry keys existing using a partial value
- by cheeseman
Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing");
Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point");
I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it.
Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword.
At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient.
for (int i = 0; i <= highestEntryPointValue; i++)
{
Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i));
if (entryKey != null)
{
count++;
}
}
