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
