Hi all,
I have a trouble in show infomation of object in layers. Because i use Vn 2000 projection (coor-dinates is big).
Ex: "POINT(580644.340722936 2188740.19828148)"
And now, I want to convert vn2000 to Wgs84.
Can you help me, please?
Thanks,

You need to use the Proj4Projection class and find in spatialreference.org the correct EPSG code or string for your internal vn 2000 projection. See the code below where I use vn 2000 UTM zone 49n projection.
Proj4Projection proj4 = new Proj4Projection();
//EPSG projection 4756 - vn-2000 / UTM zone 49n spatialreference.org/ref/epsg/3406/
proj4.InternalProjectionParametersString = Proj4Projection.GetEpsgParametersString(3406);
proj4.ExternalProjectionParametersString = Proj4Projection.GetWgs84ParametersString();
proj4.Open();
Vertex wgs84Vertex = proj4.ConvertToExternalProjection(580644.340722936, 2188740.19828148);
proj4.Close();
