Question

I am having trouble displaying all the registry keys in the startup section for Windows. I want to display all of the registry keys that tell programs to startup in a text box. I have been able to create a directory listing for the HKEY_LOCAL_MACHINE, but I can’t manage to narrow it down to the keys listed in the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run directory. Here is my code:

TreeNode localMachineNode = new TreeNode(Registry.LocalMachine.Name);
string[] localMachineSubKeys = Registry.LocalMachine.GetSubKeyNames();
foreach (string key in localMachineSubKeys)
{
    TreeNode node = new TreeNode(key, 0, 1);
}

If there is a better way to do this, i’d love to hear about it. Mind you, that is only part of my code.

Use OpenSubKey to open a key using a path:

var runs = Registry.LocalMachine.OpenSubKey(
   @"Software\Microsoft\Windows\CurrentVersion\Run");

var valueNames = runs.GetValueNames();

var values = new List<object>();
foreach (var valueName in valueNames)
{
    values.Add(runs.GetValue(valueName));
}
