Trouble writing to the registry

So this is my attempt at writing to the registry for my program to open up when windows starts.

Code:

RegistryKey App = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsft\\Windows\\CurrentVersion\\Run", true);

                if (App.GetValue("MyApp") == null)
                {
                    App.DeleteValue("MyApp", false);
                    App.SetValue("MyApp", System.Reflection.Assembly.GetExecutingAssembly().Location.ToString());
                    Console.WriteLine("Program runs at startup.");
                }
                else
                    Console.WriteLine("Program runs at startup.");

When trying to write the executable path to the registry, I get his error:

Code:

System.NullReferenceException: Object reference not set to an instance of an object.
   at App.Program.Main(String[] args) in C:\Users\Steve\Desktop\csLK\csLK\
Program.cs:line 41

Any ideas as to what I'm doing wrong? I'm a newb.

 

Don't know .NET too well, but here's my guess:
App.DeleteValue("MyApp", false);

Why are you deleting an object which you've already determined doesn't exist? Shouldn't it be CreateValue first?

 

Ahh yea I do already check for that, I had thrown in the delete in some attempt to try to make it work lol.
Still having trouble.

 

Create the value before setting it.

 

I thought that's what i was doing by doing:
RegistryKey App = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsft\\Windows\\CurrentVersion\\Run", true);

 

Once you open the subkey, create a new value in it.

 

Could you provide an example?

 

Oh wait, my bad, there's no CreateValue thing in .NET.

SOFTWARE\\Microsft\\Windows\\CurrentVersion\\Run

Spell Microsoft right

 

Man all that confusion... attributed to a spelling mistake, Thanks for the help SMR it's working.

 

Haha, mind if I lock the thread now

 

Of course not
