第149行：

throw new Exception(String.Format("Couldn't load library {0}{1}{2}", dllFilePath, Environment.NewLine, exc.Message), exc);

整个代码：

DllImport("wininet")]
        private static extern int InternetGetConnectedState(ref int lpdwFlags, int dwReserved);

        [DllImport("wininet")]
        private static extern int InternetAutodial(int dwFlags, int hwndParent);

        [DllImport("kernel32.dll")]
        private static extern IntPtr LoadLibraryEx(string dllFilePath, IntPtr hFile, uint dwFlags);

        [DllImport("kernel32.dll")]
        public static extern bool FreeLibrary(IntPtr dllPointer);

        private IntPtr LoadWin32Library(string dllFilePath)
        {
            try
            {
                IntPtr moduleHandle = LoadLibraryEx(dllFilePath, IntPtr.Zero, LOAD_WITH_ALTERED_SEARCH_PATH);
                if (moduleHandle == IntPtr.Zero)
                {
                    // I'm gettin last dll error
                    int errorCode = Marshal.GetLastWin32Error();
                    throw new ApplicationException(
                        string.Format("There was an error during dll loading : {0}, error - {1}", dllFilePath, errorCode)
                        );
                }

                return moduleHandle;
            }
            catch (Exception exc)
            {
                throw new Exception(String.Format("Couldn't load library {0}{1}{2}", dllFilePath, Environment.NewLine, exc.Message), exc);
            }
        }

private void LoadDLL()
        {
            string XulRunnerPath = @" C:\_ZAGON\TMP\DLL\GeckoEngine\xulRunner";\NCrawler\GeckoEngine\xulRunner";

            string[] files = Directory.GetFiles(XulRunnerPath, "*.dll");
            foreach (var file in files)
            {
                LoadWin32Library(file);
            }
        }

什么可能导致此错误。在胜利7工作，但当我复制到服务器我得到这个错误。

我的猜测是您的错误可能与您的服务器是x64而您的工作站是x32这一事实有关。将.NET版本中的平台目标从任何CPU更改为x32可能会解决您的问题。正确的解决方案是为x64编译freebl3.dll。
