Example
SpatialReference sr = SpatialReferences.WGS84;
SpatialReference sr2 = SpatialReferences.WebMercator;

// create some points
MapPoint point0 = MapPointBuilder.CreateMapPoint(0, 0, sr);
MapPoint point1 = MapPointBuilder.CreateMapPoint(10, 20, sr);
MapPoint point2 = GeometryEngine.Instance.Project(point1, sr2) as MapPoint;
MapPoint pointEmpty = MapPointBuilder.CreateMapPoint(sr);
MapPoint pointwithNoSR = MapPointBuilder.CreateMapPoint(1, 1);
MapPoint pointZM = MapPointBuilder.CreateMapPoint(1, 2, 3, 4, sr);

// convert to MGRS
ToGeoCoordinateParameter mgrsParam = new ToGeoCoordinateParameter(GeoCoordinateType.MGRS);
string geoCoordString = point0.ToGeoCoordinateString(mgrsParam);        // 31NAA6602100000

// use the builder to create a new point from the string.  Coordinates are the same 
MapPoint outPoint = MapPointBuilder.FromGeoCoordinateString(geoCoordString, sr, GeoCoordinateType.MGRS);    // outPoint.x = 0; outPoint.Y = 0

geoCoordString = point1.ToGeoCoordinateString(mgrsParam);             // 32QPH0460911794
outPoint = MapPointBuilder.FromGeoCoordinateString(geoCoordString, sr, GeoCoordinateType.MGRS);       // outPoint.X = 10; outPoint.Y = 20

// z, m are not transformed
geoCoordString = pointZM.ToGeoCoordinateString(mgrsParam);
outPoint = MapPointBuilder.FromGeoCoordinateString(geoCoordString, sr, GeoCoordinateType.MGRS);     // outPoint.X = 1; outPoint.Y = 2; outPoint.Z = Nan; outPoint.M = Nan;

// set the number of digits to 2 and convert
mgrsParam.NumDigits = 2;
geoCoordString = point1.ToGeoCoordinateString(mgrsParam);             // 32QPH0512
outPoint = MapPointBuilder.FromGeoCoordinateString(geoCoordString, sr, GeoCoordinateType.MGRS);     // outPoint.X = 10; outPoint.Y = 20


// convert to UTM
ToGeoCoordinateParameter utmParam = new ToGeoCoordinateParameter(GeoCoordinateType.UTM);
geoCoordString = point0.ToGeoCoordinateString(utmParam);        // 31N 166021 0000000
geoCoordString = point1.ToGeoCoordinateString(utmParam);        // 32Q 604609 2211793

// convert to DMS
ToGeoCoordinateParameter dmsParam = new ToGeoCoordinateParameter(GeoCoordinateType.DMS);
geoCoordString = point0.ToGeoCoordinateString(dmsParam);        // 00 00 00.00N 000 00 00.00E
geoCoordString = point1.ToGeoCoordinateString(dmsParam);        // 20 00 00.00N 010 00 00.00E

// convert to DDM
ToGeoCoordinateParameter ddmParam = new ToGeoCoordinateParameter(GeoCoordinateType.DDM);
geoCoordString = point0.ToGeoCoordinateString(ddmParam);        // 00 00.0000N 000 00.0000E
geoCoordString = point1.ToGeoCoordinateString(ddmParam);        // 20 00.0000N 010 00.0000E

// convert to DD
ToGeoCoordinateParameter ddParam = new ToGeoCoordinateParameter(GeoCoordinateType.DD);
geoCoordString = point0.ToGeoCoordinateString(ddParam);       // 00.000000N 000.000000E
geoCoordString = point1.ToGeoCoordinateString(ddParam);       // 20.000000N 010.000000E
