Hi,

I have a c# desktop application using WPF.

I need to check the registry from the application.
I would like to check if there is a certain registry entry at the specifica location.
1) How do I do that? Can you show me an example and guide me to a link?
2) does the application require the admin previlege to run this code (checking the registry)?

Yes. You need Admin rights to read register.

RegistryKey registerkey = Registry.LocalMachine.OpenSubKey(RegisterKey);

Open in new window


Above code could be used to read register key.

Try this
        void writeRegKey(string key)
        {
            RegistryKey registry = Registry.LocalMachine.CreateSubKey("SOFTWARE\\" + key);
            if (registry != null)
            {
                registry.SetValue("myValue", "myReturnValue");
                registry.Close();
            }
        }
    
        string readRegKey(string key)
        {
            string myRegString = "";
            RegistryKey registry = Registry.LocalMachine.CreateSubKey("SOFTWARE\\" + key);
            if (registry != null)
            {
                myRegString = registry.GetValue("myValue").ToString();
                registry.Close();
            }
            return myRegString;
        }

Open in new window


you will definitely need administrative privileges to  read/ write registery.

Can you clarify your answer on needing the admin right to read the registry?
I posted another question and they are saying you don't need the admin permission just to read the registry.

Did you guys mean you need the admin permission to write?
