AE中新建shapefile，自定义字段
代码由ESRI社区GIScafe提供
IFields pFields = new FieldsClass();
手机的利IFieldsEdit pFieldsEdit = pFields as IFieldsEdit;
IField pField = new FieldClass();
IFieldEdit pFieldEdit = pField as IFieldEdit;
pFieldEdit.Name_2 = "shape";
pFieldEdit.Type_2 = esriFieldType.esriFieldTypeGeome try;
//t up Geometry Definition
IGeometryDef pGeometryDef = new GeometryDefClass(); IGeometryDefEdit pGeometryDefEdit = pGeometryDef a s IGeometryDefEdit;
pGeometryDefEdit.GeometryType_2 = esriGeometryType.e sriGeometryPoint; //Point,line,polygon et.
奢香夫人凤凰传奇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.esriFieldTypeStrin g;
pFieldsEdit.AddField(pField);

string mappath = @"E:\data";
string layername="school";
IWorkspaceFactory pWorkspaceFactory = new ShapefileW orkspaceFactory();
IFeatureWorkspace pFeatureWorkspace = pWorkspaceFact ory.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
