arcgis二次开发arcgis二次开发

Arcgis二次开发常用源代码

1.点上生成面的代码

if (m_pFeatureLayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolygon) { IPointCollection m_pPointCollection = new PolygonClass(); object missing = Type.Missing; int icount = newFeature.XLIST.Count; if (icount < 3) return; for (int i = 0; i < icount; i++) { IPoint point = new PointClass(); point.PutCoords(newFeature.XLIST, newFeature.YLIST); m_pPointCollection.AddPoint(point, ref missing, ref missing); } IPolygon m_pPolygon = m_pPointCollection as IPolygon; if (m_pPolygon == null) { System.Windows.Forms.MessageBox.Show(“null”); return; } else { ITopologicalOperator pTopo = m_pPolygon as ITopologicalOperator; if (pTopo != null) { pTopo.Simplify(); } } IWorkspaceEdit m_pWorkspaceEdit = m_EngineEditor.EditWorkspace as IWorkspaceEdit; m_pWorkspaceEdit.StartEditOperation(); IFeature m_pFeature = m_pFeatureLayer.FeatureClass.CreateFeature(); m_pFeature.Shape = m_pPolygon as IGeometry; m_pFeature.Store(); m_pWorkspaceEdit.StopEditOperation(); }

2.文件的打开 保存 另存的代码

using System;

using System.Windows.Forms;

using ESRI.ArcGIS.esriSystem;

using ESRI.ArcGIS.SystemUI;

using ESRI.ArcGIS.Carto;

namespace SaveMapDocument

{

///

/// Summary description for Form1.

///

public class SaveMapDocument : System.Windows.Forms.Form

{

public System.Windows.Forms.TextBox txtMapDocument;

public System.Windows.Forms.Button cmdOpen;

public System.Windows.Forms.Button cmdSave;

public System.Windows.Forms.Button cmdSaveAs;

private System.Windows.Forms.OpenFileDialog openFileDialog1;

private System.Windows.Forms.SaveFileDialog saveFileDialog1;

private IMapDocument m_MapDocument;

private ESRI.ArcGIS.Controls.AxToolbarControl axToolbarControl1;

private ESRI.ArcGIS.Controls.AxPageLayoutControl axPageLayoutControl1;

private ESRI.ArcGIS.Controls.AxLicenseControl axLicenseControl1;

private ESRI.ArcGIS.Controls.AxTOCControl axTOCControl1;

///

/// Required designer variable.

///

private System.ComponentModel.Container components = null;
