Arcengine裁剪分析

方法一 ：

网上找的方法，在VS2013 ArcEngine10.1 运行时报错，通过客服得知此方法经常错误，大家可以自己测试下。

        private void StartClip(IFeatureLayer inputfeaturelayer, IFeatureClass cliplayerClass, IFeatureWorkspace pOutFeatureWorkSapce, string pOutFeatclsName)
        {

            Geoprocessor gp = new Geoprocessor();

            gp.OverwriteOutput = true;

            IFeatureClass inputfeatureclass = inputfeaturelayer.FeatureClass;
            //IFeatureClass clipfeatureclass = cliplayerClass.FeatureClass;
            IDataset dataset = inputfeatureclass as IDataset;
            //IWorkspace workspace = dataset.Workspace;
            //IFeatureWorkspace fworkspace = workspace as IFeatureWorkspace;
            IFields outfields = inputfeatureclass.Fields;
            IFeatureClass outfeatureclass = pOutFeatureWorkSapce.CreateFeatureClass(pOutFeatclsName, outfields, null, null, esriFeatureType.esriFTSimple, "Shape", "");
            ESRI.ArcGIS.AnalysisTools.Clip clipTool =
                new ESRI.ArcGIS.AnalysisTools.Clip(inputfeatureclass, cliplayerClass, outfeatureclass);
            gp.Execute(clipTool, null);
            IFeatureLayer outlayer = new FeatureLayerClass();
            outlayer.FeatureClass = outfeatureclass;
            outlayer.Name = outfeatureclass.AliasName;
            //将裁剪输出的加载到当前Mapcontrol上
            //pMap.AddLayer((ILayer)outlayer);

        }

方法二：

调用Clip工具的时候，参数直接写图层路径，经测试此方法可以实现。

        private void StartClip(string inputpath, string clippath, string mudipath)
        {

            Geoprocessor gp = new Geoprocessor();

            gp.OverwriteOutput = true;

            ESRI.ArcGIS.AnalysisTools.Clip clipTool =
                new ESRI.ArcGIS.AnalysisTools.Clip(inputpath, clippath, mudipath);
            gp.Execute(clipTool, null);

        }
