C#

Hello i was trying to fix one method of anti-dumping in memory the method is to delete the header. And the code is:

public enum FreeConsts : uint
        {
            MEM_RELEASE = 0x8000
        }
    	[DllImport("kernel32.dll")]
		private static extern IntPtr ZeroMemory(IntPtr addr, IntPtr size);
		
		[DllImport("kernel32.dll")]
		private static extern IntPtr VirtualProtect(IntPtr lpAddress, IntPtr dwSize, IntPtr flNewProtect, ref IntPtr lpflOldProtect);
		
		[DllImport("kernel32")]
        private static extern bool VirtualFree(IntPtr lpAddress, UInt32 dwSize, FreeConsts dwFreeType);
		
		[DllImport("kernel32.dll")]
		public static extern IntPtr GetModuleHandle(string lpModuleName);
		
		public static void EraseHeader()
		{
		IntPtr address = GetModuleHandle(null);
		IntPtr dwOld = default(IntPtr);
		VirtualProtect(address, (IntPtr)4096, (IntPtr)0x40, ref dwOld);
		ZeroMemory(address, (IntPtr)4096);
		VirtualFree(address, 0, FreeConsts.MEM_RELEASE);
		}

However many times show me:

been thrown by the target of an invocation. ---> System.TypeInitializationExcept
ion: The type initializer for 'T???????????????????' threw an exception. ---> Sy
stem.TypeInitializationException: The type initializer for 'System.Management.Ma
