IGraphicsContainer pGraphicsContainer = axMapControl1.ActiveView.GraphicsContainer;
pGraphicsContainer.Reset();
IElement ele = pGraphicsContainer.Next();
while(ele!=null)
{
if (ele.Geometry is IPoint)
{
IFeature feature = pointFeatureClass.CreateFeature();
feature.Shape = ele.Geometry;
//feature.set_Value(0, value);
feature.Store();
}
ele = pGraphicsContainer.Next();
}
pGraphicsContainer.Reset();
IElement ele = pGraphicsContainer.Next();
while(ele!=null)
{
if (ele.Geometry is IPoint)
{
IFeature feature = pointFeatureClass.CreateFeature();
feature.Shape = ele.Geometry;
//feature.set_Value(0, value);
feature.Store();
}
ele = pGraphicsContainer.Next();
}
