How to add a feature to a feature class from shape file?

Question

Hi Experts:

Following is the code I wrote to add a point feature to a shape file.

//*********************************************************************
public static void AddToFeatureClass(IFeatureClass baseClass, IGeometry newGeometry)
{
    IFeature newFeature = baseClass.CreateFeature();
    newFeature.Shape = newGeometry;
    (newFeature.Shape as IZAware).ZAware = (newGeometry as IZAware).ZAware;
    (newFeature.Shape as IMAware).MAware = (newGeometry as IMAware).MAware;
}
//*********************************************************************

The code could run through and add a record into the shape file. However, in ArcMap attribute table there is no response when I zoom/pan/flash the added point. When I idenfy the point I found that it has an undefined location (see the following screenshoot).

When I use the Visual Studio debug mode to inspect the new feature, I couldn't find any issue.

What does it happen? How shall I fix the issue? If more information is needed please let me know. Thank you.

If you don't call IFeature.Store then any changes you make to the feature will not be saved.
