ArcGIS Pro SDK 将几何输出为要素

需求：

在获取到一个几何（geometry）的数据，我们需要将其输出为要素

解决方案：

1.创建要素

2.将几何写进要素中

//构建面几何
ArcGIS.Core.Geometry.Polygon mfGeoPolygon = new PolygonBuilderEx(mfGeoList, mapFrame.Map.SpatialReference).ToGeometry();
// 用于存储消息的字符串
string message = string.Empty;
// 标记创建结果的布尔值
bool creationResult = false;
var testName = $@"示例点{DateTime.Now:HHmmss}";
//创建要素类var hasZ = false;
var hasM = false;
// 创建一个ShapeDescription
var shapeDescription = new ShapeDescription(GeometryType.Polygon, SpatialReferences.WebMercator){HasM = hasM,HasZ = hasZ};// 定义字段var stringFieldDescription = new ArcGIS.Core.Data.DDL.FieldDescription("字符串字段", FieldType.String);// 打开默认数据库gdbusing (Geodatabase gdb = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(gdbPath)))){var fcName = $@"{testName}";try{// 收集字段列表var fieldDescriptions = new List<ArcGIS.Core.Data.DDL.FieldDescription>() {stringFieldDescription};// 创建FeatureClassDescriptionvar fcDescription = new FeatureClassDescription(fcName, fieldDescriptions, shapeDescription);// 创建SchemaBuilderSchemaBuilder schemaBuilder = new SchemaBuilder(gdb);// 将创建任务添加到DDL任务列表中schemaBuilder.Create(fcDescription);// 执行DDLbool success = schemaBuilder.Build();// 打开示例要素using FeatureClass enterpriseFeatureClass = gdb.OpenDataset<FeatureClass>(fcName);// 创建编辑操作对象EditOperation editOperation = new EditOperation();editOperation.Callback(context =>{// 获取要素定义FeatureClassDefinition featureClassDefinition = enterpriseFeatureClass.GetDefinition();// 创建RowBufferusing RowBuffer rowBuffer = enterpriseFeatureClass.CreateRowBuffer();// 写入字段值//rowBuffer["SHP名称"] = "新名称";// 设置一组点集合，用来构面rowBuffer[featureClassDefinition.GetShapeField()] = mfGeoPolygon;// 在表中创建新行using Feature feature = enterpriseFeatureClass.CreateRow(rowBuffer);context.Invalidate(feature);      // 标记行为无效状态}, enterpriseFeatureClass);try{// 执行编辑操作creationResult = editOperation.Execute();// 如果操作失败，存储错误消息if (!creationResult) { message = editOperation.ErrorMessage; }}catch (GeodatabaseException exObj){// 如果出现地理数据库异常，存储异常消息message = exObj.Message;throw;}if (!string.IsNullOrEmpty(message)){// 如果消息不为空，显示消息框MessageBox.Show(message);}}catch (Exception ex){MessageBox.Show($@"Exception: {ex}");}
