Merage

AE+C# 实现MERGE,

代码参考ESRI中国社区，忘了哪个帖子了。。。
代码中路径等直接写上去了

//合并图层的集合

ILayer pLayer;

IArray pArray;

pArray = new ArrayClass();

            for (int i = 0; i < this.axMapControl1.LayerCount; i++)
              {
                pLayer = this.axMapControl1.get_Layer(i);
                pArray.Add(pLayer);
               }

//定义输出图层的fields表

ITable pTable;

IFeatureLayer pFeatureLayer;

IFeatureClass pFeatureClass;

pLayer = this.axMapControl1.get_Layer(0);

pTable = (ITable)pLayer;

pFeatureLayer=(IFeatureLayer)pLayer;

pFeatureClass = pFeatureLayer.FeatureClass;

            //判断图层是否大于2个
            if(this.axMapControl1.LayerCount< 2)
             {
                MessageBox.Show("Table QI failed");
                return;
              }

//输出文件类型

IFeatureClassName pFeatureClassName;

IDatasetName pDatasetName;

IWorkspaceName pNewWSName;

pFeatureClassName = new FeatureClassNameClass();

pFeatureClassName.FeatureType = esriFeatureType.esriFTSimple;

pFeatureClassName.ShapeFieldName = "Shape";

pFeatureClassName.ShapeType = pFeatureClass.ShapeType;

//输出shapefile的名称和位置

pNewWSName = new WorkspaceNameClass();

pNewWSName.WorkspaceFactoryProgID="esriDataSourcesFile.ShapefileWorkspaceFactory";

pNewWSName.PathName = "E:\\data";

pDatasetName = (IDatasetName)pFeatureClassName;

pDatasetName.Name = "Merge_result";

pDatasetName.WorkspaceName = pNewWSName;

//合并图层

IFeatureClass pOutputFeatClass;

IBasicGeoprocessor pBasicGeop;

pBasicGeop = new BasicGeoprocessorClass();

pOutputFeatClass=pBasicGeop.Merge(pArray,pTable,pFeatureClassName);

//将合并后的图层加载到Map中

IFeatureLayer pOutputFeatLayer;

pOutputFeatLayer = new FeatureLayerClass();

pOutputFeatLayer.FeatureClass = pOutputFeatClass;

pOutputFeatLayer.Name = pOutputFeatClass.AliasName;

this.axMapControl1.AddLayer(pOutputFeatLayer as ILayer, 0);
