AE中新建shapefile，自定义字段

代码由ESRI社区GIScafe提供

           IFields pFields = new FieldsClass();
            IFieldsEdit pFieldsEdit = pFields as IFieldsEdit;
            IField pField = new FieldClass();
            IFieldEdit pFieldEdit = pField as IFieldEdit;
            pFieldEdit.Name_2 = "shape";
            pFieldEdit.Type_2 = esriFieldType.esriFieldTypeGeometry;

            //set up Geometry Definition
            IGeometryDef pGeometryDef = new GeometryDefClass();
            IGeometryDefEdit pGeometryDefEdit = pGeometryDef as IGeometryDefEdit;
            pGeometryDefEdit.GeometryType_2 = esriGeometryType.esriGeometryPoint;  //Point,line,polygon et.
            pGeometryDefEdit.SpatialReference_2 = axMapControl1.SpatialReference;

            pFieldEdit.GeometryDef_2 = pGeometryDef;
            pFieldsEdit.AddField(pField);

            //新建字段
            pField = new FieldClass();
            pFieldEdit = pField as IFieldEdit;
            pFieldEdit.Length_2 = 15;
            pFieldEdit.Name_2 = "SchoolName";
            pFieldEdit.AliasName_2 = "SchoolName";
            pFieldEdit.Type_2 = esriFieldType.esriFieldTypeString;
            pFieldsEdit.AddField(pField);

            string mappath = @"E:\data";
            string layername="school";
            IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();
            IFeatureWorkspace pFeatureWorkspace = pWorkspaceFactory.OpenFromFile(mappath,0) as IFeatureWorkspace;
            pFeatureWorkspace.CreateFeatureClass(layername+".shp",pFields,null,null,esriFeatureType.esriFTSimple,"shape","");
            axMapControl1.AddShapeFile(mappath,layername+".shp");

代码中路径名称可以自定义
