地图文档数据加载:
 (1)

/// <summary>

         /// 加载地图文档数据

         /// </summary>

         /// <param name="sender"></param>

         /// <param name="e"></param>

         private void mnuFile_1_Click(object sender, System.EventArgs e)

         {

              this.openFileDialog1.FilterIndex =2;

              this.openFileDialog1.Filter="ArcMap Document(*.mxd)|*.mxd|ArcMap Document(*.mxt)|*.mxt|ArcMap Document(*.pmf)|*.pmf";

              //定义文件名称

              string filePath=null;

              if(this.openFileDialog1.ShowDialog()==DialogResult.OK )

              {

                   filePath=this.openFileDialog1.FileName;

              }

              else

              {

                   return;

              }

              //如果地图文档名称不为空则加载文档数据

              if(filePath!=null && filePath.Length >0)

              {

                   //检查地图文档是否存在

                   if (axMapControl1.CheckMxFile(filePath))

                   {

                       //载入地图

                       axMapControl1.LoadMxFile(filePath,Type.Missing,Type.Missing);

                   }

              }

        }

(2)采用IMapDocument对象
 

private void OpenDocument(string filepath)

         {

              try

              {

                   IMapDocument pMapDocument=new MapDocumentClass();

                   //将文档数据加载到pMapDocument对象中

                   pMapDocument.Open (filepath,"");

                   for(int i=0;i<pMapDocument.MapCount;i++)

                   {

                       //遍历每个map对象,并将map对象加载到MapControl

                       this.axMapControl1.Map =pMapDocument.get_Map(i);

                   }

                   //刷新地图

                   this.axMapControl1.Refresh();

 

              }
