地理处理服务 - 调用后清空内存
我正在关注 ADF 库的此示例
我实际上是在画一个圆圈具有地理处理服务的点。半径约为20公里。
该代码工作正常，但“清除”例程却不然。每次我从以前的数据中清除地图时，缓冲服务的内存也不会被清除，我得到这个
清除”例程的代码与示例相同，但不起作用：
// Clears features from all graphics layers in the resource specified by _graphicsResourceName
protected void ClearGraphics()
{
// Retrieve the resource and clear its graphics dataset
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource graphicsMapResource =
Map1.GetFunctionality(_graphicsResourceName).Resource as
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource;
graphicsMapResource.Graphics.Clear();
// This won't work too
GeoprocessingResourceManager1.GetResource(0).ClearState();
// Refresh the resource and copy the map's callback results to the callback results collection so
// the graphics are removed from the map
Map1.RefreshResource(graphicsMapResource.Name);
_callbackResultCollection.CopyFrom(Map1.CallbackResults);
}
这应该很简单，但我不知道如何解决这个问题..我找到的唯一解决方案是重新启动IIS 服务器显然非常糟糕，
有人可以吗？帮帮我吗？
I'm following this sample for ADF libraries
I'm practically drawing a circle around a point with a geoprocessing service. The radius is about 20 km.
The code is working fine, but the "Clear" routine isn't. Every time I clear the map from the previous data, the memory of the buffer service isn't cleared too and I get this
The code of the "Clear" routine is the same of the sample, but isn't working:
// Clears features from all graphics layers in the resource specified by _graphicsResourceName
protected void ClearGraphics()
{
// Retrieve the resource and clear its graphics dataset
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource graphicsMapResource =
Map1.GetFunctionality(_graphicsResourceName).Resource as
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource;
graphicsMapResource.Graphics.Clear();
// This won't work too
GeoprocessingResourceManager1.GetResource(0).ClearState();
// Refresh the resource and copy the map's callback results to the callback results collection so
// the graphics are removed from the map
Map1.RefreshResource(graphicsMapResource.Name);
_callbackResultCollection.CopyFrom(Map1.CallbackResults);
}
This should be simple but I can't figure out how to solve this.. the only solution I found is to restart the IIS server which is obviously very bad
Can someone please help me out?

通过清除作业队列解决
Solved by clearing the jobs' queue
我通常使用 GraphicsLayerFunctionality.GraphicsDataSet.Tables.Clear();
或
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource myMapResource
myMapResource.Graphics.Tables.Remove(图形元素);
您实际上正在处理 .NET 数据集
I usually use GraphicsLayerFunctionality.GraphicsDataSet.Tables.Clear();
or
ESRI.ArcGIS.ADF.Web.DataSources.Graphics.MapResource myMapResource
myMapResource.Graphics.Tables.Remove(graphics element);
You are actually dealing with a .NET DataSet
