大家好，又见面了，我是你们的朋友全栈君。
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;
///
