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;
}
}
