Hi,
I thought if you were looking for a true arc (section of a circle), you could use the Buffer function around a point, and then try to get at a section of the curve. But not what you want...
I didn't find much on the format of a serialized shape, but did serialize a line and a polygon from a shape file.
The first character looks to be the shape type
The second may have to do with multi-part shapes (not sure)
The rest of the string are a series of coordinate pairs
The POLYLINE string looks like:
3;0;494565.281250|51498.046875|494657.218750|51495.484375|494711.125000|51494.199219|
The POLYGON string looks like:
5;0;494665.084509|51865.464651|494706.328594|51863.942218|494709.495943|51759.419716|494686.500000|51765.679688|494600.835820|51789.397957|494609.956644|51799.126836|494609.984083|51799.169370|494610.292331|51799.509782|494654.545391|51853.532999|494665.084509|51865.464651|
I think the "5" indicates a polygon, also the last and first points are the same. So if you took the first point coordinate pair of a polyline string and copied it to the end of the string, and changed the first character "3" to a "5", you would have the string of a polygon based on a closed polyline. You could then use CreateFromString (string Serialized) to get the shape.
-Good Luck
