ArcEngine序列化IFeatureRenderer对象 

 1 OpenFileDialog openFileDialog1 = new OpenFileDialog();
 2                openFileDialog1.Filter = "lyr文件(*.lyr)|*.lyr";
 3             openFileDialog1.InitialDirectory = @"d:\data";
 4             openFileDialog1.Multiselect = false;
 5             DialogResult pDialogResult = openFileDialog1.ShowDialog();
 6             if (pDialogResult != DialogResult.OK)
 7                 return;
 8             string pFileName = openFileDialog1.FileName;
 9             axMapControl1.AddLayerFromFile(pFileName);
10             //axMapControl1.ActiveView.Refresh();
11             axMapControl1.Extent = axMapControl1.FullExtent;
12             ILayer player = axMapControl1.get_Layer(0);
13             IFeatureLayer pfeatlayer = player as IFeatureLayer;
14             IGeoFeatureLayer pgeo=pfeatlayer as IGeoFeatureLayer;
15             IFeatureRenderer ren= pgeo.Renderer as IFeatureRenderer;
16             IPersistStream stream = ren as IPersistStream;
17 
18             ESRI.ArcGIS.esriSystem.IMemoryBlobStream pMemoryBlobStream = new ESRI.ArcGIS.esriSystem.MemoryBlobStreamClass();
19 
20             IObjectStream pObjectStream = new ObjectStreamClass();
21             pObjectStream.Stream = pMemoryBlobStream;
22             IPersistStream pPersistStream = (IPersistStream)ren;
23             pPersistStream.Save((IStream)pObjectStream, 0);
24             pMemoryBlobStream.SaveToFile(@"d:\a.render");

程序还出现一个错误，修改Ae的Dll引用的属性“嵌入式互操作程序”为false。
