The first thing to do is check the return value.
The documentation[^] says:

If the function succeeds, the return value specifies the number of fonts added.
If the function fails, the return value is zero. No extended error information is available.

So start by looking to see if it returns zero or one.
However, it also says:

"Any application that adds or removes fonts from the system font table should notify other windows of the change by sending a WM_FONTCHANGE message to all top-level windows in the operating system. The application should send this message by calling the SendMessage function and setting the hwnd parameter to HWND_BROADCAST.
When an application no longer needs a font resource that it loaded by calling the AddFontResource function, it must remove that resource by calling the RemoveFontResource function.
This function installs the font only for the current session. When the system restarts, the font will not be present. To have the font installed even after restarting the system, the font must be listed in the registry."

So you don't just call the add a font method, you need to notify other apps, and almost certainly add it to the registry.

Thanks OriginalGriff. It returns one(of course i don't see my font in c:\windows\fonts) and I'm not going to remove it. So, remains one issue:list in registry. how? have you some sample?

No, I've never needed to.
But...google has found this:
http://stackoverflow.com/questions/21986744/how-to-install-a-font-programatically-c

Which shows the registry code. Note: you are probably going to need UAE to do this (understandably!)

Note that your font source must add to Resource of project

C#

File.Copy("yourfont.ttf", Path.Combine("C:\\Windows", "Fonts" + "yourfont.ttf"),true);

RegistryKey fontkey= Microsoft.Win32.Registry.LocalMachine.CreateSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts");

fontkey.SetValue("yourfont", "yourfont.ttf");
fontkey.Close();
