使用ae前需许可认证:加在Program main函数里面

//签入AE运行许可
                if (!RuntimeManager.Bind(ProductCode.Engine))
                {
                    if (!RuntimeManager.Bind(ProductCode.Desktop))
                    {
                        MessageBox.Show("Unable to bind to ArcGIS runtime.Application will be shut down.");
                          return;
                    }
                }
