対処法
Objects stored in session state must be serializable if the mode is SQL Server. It's not very clear if ESRI web controls save unserializeable objects into session variables.Two workarounds were sent to the user.1. Remove all resource items and only add that single map resource item that should be visible.2. Turn off all layers inside those map resource items that should be invisible. Only layers in one resource item is set visible.Here is the code snippet for workaround 2: private void SetLayersVisibility(int resource_index, bool visibleSetting) { ESRI.ArcGIS.ADF.Web.DataSources.IMapFunctionality mf = (ESRI.ArcGIS.ADF.Web.DataSources.IMapFunctionality)Map1.GetFunctionality(resource_index); ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapFunctionality ags_mf = (ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapFunctionality)mf; //ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapResourceBase ags_mr = (ESRI.ArcGIS.ADF.Web.DataSources.ArcGISServer.MapResourceBase)qfunc.Resource; ESRI.ArcGIS.ADF.ArcGISServer.MapDescription mapdescription; mapdescription = ags_mf.MapDescription; ESRI.ArcGIS.ADF.ArcGISServer.LayerDescription[] layerdescs = mapdescription.LayerDescriptions; for (int layer_index = 0; layer_index < layerdescs.Length; layer_index++) { ESRI.ArcGIS.ADF.ArcGISServer.LayerDescription featureLayer = layerdescs[layer_index]; featureLayer.Visible = visibleSetting; } } private string SwitchMapService(string serviceName) { for (int resource_index = 0; resource_index < MapResourceManager1.ResourceItems.Count; resource_index++) { if (MapResourceManager1.ResourceItems[resource_index].Name != serviceName) { SetLayersVisibility(resource_index, false); } else { SetLayersVisibility(resource_index, true); } } Map1.Refresh(); Toc1.Refresh(); Map1.CallbackResults.AddRange(Toc1.CallbackResults); string mapcallbackresults = Map1.CallbackResults.ToString(); return mapcallbackresults; }
