代码如下：
aLayer = new VectorLayer(ShapeTypes.Point);
                    aLayer.LayerName = "预警信号";
                    aLayer.LegendScheme =new LegendScheme(ShapeTypes.Point);  
                    aLayer.LegendScheme.ImportFromXMLFile("alarm.lgs");
                    aLayer.Visible = true;
aLayer.EditAddField("STATION", typeof(string));
                    aLayer.EditAddField("LON", typeof(double));
                    aLayer.EditAddField("LAT", typeof(double));
                    aLayer.EditAddField("alarmcolor", typeof(double));
                    aLayer.EditAddField("alarmcontent", typeof(double));
                    //Add shape
                    foreach (DictionaryEntry de in alarmname)
                    {
                        PointShape aPS = new PointShape();
                        PointD aPoint = new PointD();
                        aPoint.X = Convert.ToDouble(lonhash[de.Key]);
                        aPoint.Y = Convert.ToDouble(lathash[de.Key]);
                        aPS.Point = aPoint;
                        int shapeNum = aLayer.ShapeNum;
                        if (aLayer.EditInsertShape(aPS, shapeNum))
                        {
                            //Edit record value
                            aLayer.EditCellValue("STATION", shapeNum, de.Key);
                            aLayer.EditCellValue("LON", shapeNum, aPoint.X);
                            aLayer.EditCellValue("LAT", shapeNum, aPoint.Y);
                            aLayer.EditCellValue("alarmcolor", shapeNum, Convert.ToString(alarmname[de.Key]) + Convert.ToString(alarmcolor[de.Key]));
                            aLayer.EditCellValue("alarmcontent", shapeNum, alarmcontent[de.Key]);
                        }
                    }
                    //Add layer
                    frmain.G_LayerLegend.AddLayer(aLayer, true);
                    this.mapView1.PaintLayers();

结果如下

没有得到预警信号的图标，麻烦看下到底是什么原因造成的

MeteoInfo

可能是字段类型的问题，用于设置图例的字段是alarmcolor，看起来应该是字符型string，你可以试着将添加此字段的代码修改如下：
aLayer.EditAddField("alarmcolor", typeof(string));

修改了以后还是这样。

从结果来看，最后执行的还是这段代码Color="#2D6697" DrawShape="True" OutlineColor="Black" Size="10" Style="Circle" DrawOutline="True" DrawFill="True"
