C# AccessViolationException

Question

I am installing a ttf file into my C:/Windows/Fonts folder from my C# WPF application.While installing I am getting System.AccessViolation Exception. My code is below:

int result = -1;
            int error = 0;
            var windowsDirectory = Environment.GetEnvironmentVariable("SystemRoot") + "\\Fonts\\";
            var directoryInfo = new DirectoryInfo("../../Assets/Fonts");

            foreach (var file in directoryInfo.GetFiles())
            {
                result = AddFontResource((new FileInfo(windowsDirectory + file.Name)).ToString());
                error = Marshal.GetLastWin32Error();
                if (error != 0)
                {
                    System.Diagnostics.Debug.WriteLine(new Win32Exception(error).Message);
                }
                else
                {
                    System.Diagnostics.Debug.WriteLine((result == 0) ? "Font is already installed." :
                                                      "Font installed successfully.");
                }
            }

How do Iresolve my issue

Have you looked up the error type on MSDN? It's very clear what the issue is after you read up on it. — Brian Driscoll, Mar 28 '14 at 13:37
i know what the issue is. I am trying to write to C:/Windows/Fonts folder which needs administrative rights. I am asking is there a way to resolve it directly from the WPF C# code — user2877090, Mar 28 '14 at 13:42

In case the exception is really based on missing administrator rights, you might want to read this articel about how to set up your app config for administrator rights.
