Answer 1

Here's the class that allows you to read and write windows registy. All you need to do with it is to find the proper value to read.

Answer 2

you can use the following code to get the version key value:

RegistryKey key= Registry.LocalMachine.OpenSubKey("SOFTWARE").OpenSubKey("leaf").OpenSubKey("monitor ");
string version = key.GetValue("version");

Edit: check now :)

Answer 3

Wael's code works fine, but there's a couple other (slightly syntactically cleaner) ways to do it, for example:

• OpenSubKey knows how to open several subkeys at once:

RegistryKey key = Registry.LocalMachine.OpenSubKey(@"Software\leaf\monitor");

• Additionally, if you only need to get a value, which your question asks about, it's even simpler (and this allows you to set a fallback value if your target key doesn't exist, avoiding a thrown exception if you use OpenSubKey):

string version = Registry.GetValue(@"HKEY_LOCAL_MACHINE\Software\leaf\monitor", "version", "0");
