爆出错误：The Geometry has no Z values

ArcGis添加地图标注，爆出错误：The Geometry has no Z values

解决方法如下：

public bool AddFeature( ESRI.ArcGIS.Geometry.IGeometry geometry,System.Collections.Generic.Dictionary<string ,object> properties)
 
        {
 
            try
 
            {
 
                ESRI.ArcGIS.Geodatabase.IFeature feature = _featureLayer.FeatureClass.CreateFeature();
 
                int index;
 
                index = feature.Fields.FindField("Shape");
 
                IGeometryDef pGeometryDef;
 
                pGeometryDef = feature.Fields.get_Field(index).GeometryDef as IGeometryDef;
 
                if (pGeometryDef.HasZ)
 
                {
 
                    IZAware pZAware = (IZAware)geometry;
 
                    pZAware.ZAware = true;
 
                    //IZ iz1 = (IZ)geometry;
 
                    //iz1.SetConstantZ(0);  //将Z值设置为0
 
                    IPoint point = (IPoint)geometry;
 
                    point.Z = 0;
 
                }
 
                else
 
                {
 
                    IZAware pZAware = (IZAware)geometry;
 
                    pZAware.ZAware = false;
 
                }
 
                if (pGeometryDef.HasM)
 
                {
 
                    IMAware pMAware = (IMAware)geometry;
 
                    pMAware.MAware = true;
 
                }
 
                else
 
                {
 
                    IMAware pMAware = (IMAware)geometry;
 
                    pMAware.MAware = false;
 
                }
 
                feature.Shape = geometry;
 
                foreach (string key in properties.Keys)
 
                {
 
                    SetFeatueProperty(feature, key, properties[key]);
 
                }
 
                feature.Store();  
 
                return true;
 
            }
 
            catch (Exception ee)
 
            {
 
                return false;
 
            }
 
        }
