之前编写这段代码，发现一直没有C#编写的，现在贴出来，希望对大家有用
此程序实现保存后的文件，不能在ArcScene里面打开。但下面的打开程序一切通吃。。呵呵
打开代码：
openFileDialog1.Title = "打开Scene文档"; openFileDialog1.Filter = "Scene文档(*.sxd)|*.sxd"; openFileDialog1.ShowDialog(); string filename = openFileDialog1.FileName; if (axSceneControl1.CheckSxFile(filename)) axSceneControl1.LoadSxFile(filename); else { IScene pScene = axSceneControl1.Scene; IMemoryBlobStream mbStream = new MemoryBlobStreamClass(); IObjectStream objectStream = new ObjectStreamClass(); mbStream.LoadFromFile(filename); IPersistStream pPersistStream = (ESRI.ArcGIS.esriSystem.IPersistStream)pScene; objectStream.Stream = mbStream; pPersistStream.Load(objectStream); }
保存代码：
IMemoryBlobStream mbStream = new MemoryBlobStreamClass(); IObjectStream objectStream = new ObjectStreamClass(); objectStream.Stream = mbStream; IPersistStream persistStream = (ESRI.ArcGIS.esriSystem.IPersistStream)axSceneControl1.Scene; persistStream.Save(objectStream, 1);
saveFileDialog1.Title = "保存Scene文档"; saveFileDialog1.Filter = "保存Scene文档(*.sxd)|*.sxd"; saveFileDialog1.ShowDialog(); string filename = saveFileDialog1.FileName;
mbStream.SaveToFile(filename); MessageBox.Show("OK");
