axMapControl

新建mxd.cs

/*
ArcGIS Engine提供了保存Mxd文件的类MapDoment。但在具体保存MXD文件过程中有下面几种情况：   

1 直接使用IMapDocument接口的Open方法来打开MXD文件，编辑过后进行保存。    
2 使用Engine中带的OpenDocument方法来打开MXD文件，然后编辑过之后要进行保存。    
3 使用自己写的添加数据的工具直接添加数据，也就是说一开始没有MXD文件，在编辑完之后需要把当前的地图保存为一个MXD文件。
过程描述

解决方法：   
首先这三种情况都可以使用Engine中自带的SaveDoument的工具进行保存    
1 这种情况比较简单，直接使用IMapDocument的save或者saveas的方法来进行保存就可以，可以在帮助中查到例子。    

2 这种情况可使用下面的代码进行保存，    
*/
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.SaveAs ("d:\aa2.mxd",true,true);   


//3 这种情况使用的代码稍微有点不同：   
IMxdContents pMxdC;    
pMxdC = axMapControl1.Map as IMxdContents ;    
IMapDocument pMapDocument = new MapDocumentClass ();    
pMapDocument.New ("d:\aa3.mxd");    
IActiveView pActiveView = axMapControl1.Map as IActiveView ;    
pMapDocument.ReplaceContents (pMxdC);    
pMapDocument.Save (true,true);


//---------------------------------------------------
   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:\TEST\untitled.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);

新建shp.cs

        private void btnCreatAddShp_Click(object sender, EventArgs e)
        {
            DataOperator dataOperator = new DataOperator(axMapControl1.Map);
            IFeatureClass featureClass = dataOperator.CreatShapefile("c:\\", "ShapefileWorkspace", "ShapefileSample");
            if (featureClass == null)
            {
                MessageBox.Show("创建失败");
                return;c
            }
            bool bRes = dataOperator.AddFeatureClassToMap(featureClass, "ObservationStation");
            return;
        }

添加MDX.cs

1        private void btnLoadMxd_Click(object sender, EventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Title = "打开MXD文件";
            ofd.Filter = "mxd|*.mxd";
            if (ofd.ShowDialog()==DialogResult.OK)
            {
                string filePath = ofd.FileName;
                if (axMapControl1.CheckMxFile(filePath))
                {
                    axMapControl1.MousePointer = ESRI.ArcGIS.Controls.esriControlsMousePointer.esriPointerHourglass;
                    axMapControl1.LoadMxFile(filePath, 0, Type.Missing);
                    axMapControl1.MousePointer = ESRI.ArcGIS.Controls.esriControlsMousePointer.esriPointerDefault;
                    //
                    axMapControl1.Extent = axMapControl1.FullExtent;
                }
                else
                    MessageBox.Show("不是有效的Mxd");
            }
        }

添加文字.cs

        private void axMapControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.IMapControlEvents2_OnMouseDownEvent e)
        {
            IGeometry geometry = this.axMapControl1.TrackLine();
            //drawMapShape(geometry);
            drawMapText(geometry);
        }
        private void drawMapShape(IGeometry geometry)
        {
            IRgbColor color = new RgbColor();
            color.Red = 255;
            object symbol = null;
            if (geometry.GeometryType == esriGeometryType.esriGeometryPolyline || geometry.GeometryType == esriGeometryType.esriGeometryLine)
            {
                ISimpleLineSymbol simpleLineSymbol = new SimpleLineSymbol();
                simpleLineSymbol.Color = color;
                simpleLineSymbol.Width = 5;
                symbol = simpleLineSymbol;
            }
            else
            {
                ISimpleFillSymbol simpleFillSymbol = new SimpleFillSymbol();
                simpleFillSymbol.Color = color;
                symbol = simpleFillSymbol;
            }
            axMapControl1.DrawShape(geometry, ref symbol);
        }

        private void drawMapText(IGeometry geometry)
        {
            IRgbColor color = new RgbColor();
            color.Blue = 255;
            ITextSymbol tSymbol = new TextSymbol();
            tSymbol.Color = color;
            object symbol = tSymbol;
            this.axMapControl1.DrawText(geometry,"测试",ref symbol);
        }

    }
