I have some selected feature as Polygon in SDE geo database show in map control. They are side-by-side features but now I want to merge them into one by code . How can I do this, anyone has any example code ? I use ArcGIS engine 9.3 and C# thank you Cuongdx
I used to use this code but I can't union 2 adjacent polygons, result return only one polygon (polygon 1 to union ). Two polygons don't intersect , just have a common segment. How can I fix that?
