AE中保存Mxd文档的几种方式

文档对象主要由IMapdocument和IMxdContents接口完成的。IMapDocument定义了操作和管理文档对象的方法和属性，包括读、写和保存一个文档文件(*.mxd)。

   public void ReplaceContents (IMxdContents pObject);保存修改；

 public void Save ( bool bUseRelativePaths,bool bCreateThumnbail);

 public void SaveAs (string sDocument,bool bUseRelativePaths,bool bCreateThumnbail);

IMxdContents接口：Provides access to members to pass data into and out off a MXD map document file. Coclasses that implement this interface can limited the implementation to one property if required.

1 新建一个Mxd空白文档：

          string path=@"f:TESTuntitled.mxd";

            MapDocument pMapDocument = new MapDocumentClass();

            pMapDocument.New(path);

            pMapDocument.Open(path, "");

            axMapControl1.Map = pMapDocument.get_Map(0);

2 在打开一个Mxd文档进行修改、编辑再保存在原文件里面：

           IMxdContents pMxdC;

            pMxdC = axMapControl1.Map as IMxdContents;

            IMapDocument pMapDocument = new MapDocumentClass();

            pMapDocument.Open(axMapControl1.DocumentFilename, "");

            IActiveView pActiveView = axMapControl1.Map as IActiveView;

            pMapDocument.ReplaceContents(pMxdC);

            pMapDocument.Save(true, true);

3 自定义加载各种数据,也就是一开始就没有Mxd文档，之后进行修改、编辑，把当前地图保存为一个Mxd文档

          SaveFileDialog Sfd = new SaveFileDialog();

            Sfd.Title = "另存文档";

            Sfd.Filter = "(*.mxd)|*.mxd";

            Sfd.ShowDialog();

            string path = Sfd.FileName;

            IMxdContents pMxdC;

            pMxdC = axMapControl1.Map as IMxdContents;

            IMapDocument pMapDocument = new MapDocumentClass();

            pMapDocument.New(path);

            IActiveView pActiveView = axMapControl1.Map as IActiveView;

            pMapDocument.ReplaceContents(pMxdC);

            pMapDocument.Save(true, true);
