Well, apparently the registry seems to have lost some of its importance with the arrival of .NET, at least that's the
impression I seem to get. But luckily for us, Microsoft has given us two nice classes for doing just about anything we want to do
with the registry. The classes are
Microsoft.Win32.Registry. They have
both been put into the
Microsoft.Win32 namespace as you can see because the registry is totally Microsoft Win32
specific. Without too much fuss, let's get into business and try and do some of the stuff we normally do with the registry.
Reading the registry
RegistryKey rkey = Registry.LocalMachine;
listBox1.Items.Add("RegisteredOwner :- " +
listBox1.Items.Add("RegisteredOrganization :- " +
listBox1.Items.Add("ProductName :- " +
listBox1.Items.Add("CSDVersion :- " +
listBox1.Items.Add("SystemRoot :- " +
Writing to the registry
rkey = Registry.CurrentUser;
rkey1 = rkey.OpenSubKey("Software",true);
RegistryKey rkey2 = rkey1.CreateSubKey("Tweety");
If you open regedit, you'll see that the new key has been added and the values have indeed been written correctly.
Okay, we've read from and written into the registry. Now let's enumerate some values.
rkey1 = rkey.OpenSubKey("Software\\Microsoft\\" +
"Internet Account Manager\\Accounts\\00000001");
string s_arr = rkey1.GetValueNames();
foreach(String s in s_arr)
listBox1.Items.Add(s + " :- " + rkey1.GetValue(s));
Well, that's about it I guess. This was originally written as part of an internal tutorial. I didn't modify it too much except
for taking better screenshots.
