ArcGIS Pro 2.6 API Reference Guide
ImportFromWKT Method (IGeometryEngine)
Example 

ArcGIS.Core.Geometry Namespace > IGeometryEngine Interface : ImportFromWKT Method
A combination of WKTImportFlags which determines how the geometry is imported.
The input WKT string. The string must be OGC compliant.
The spatial reference of the output geometry.
Creates a geometry from the input well-known text string.
Syntax

Parameters

importFlags
A combination of WKTImportFlags which determines how the geometry is imported.
wktString
The input WKT string. The string must be OGC compliant.
spatialReference
The spatial reference of the output geometry.

Return Value

A Geometry that corresponds to the wktString.
Exceptions
ExceptionDescription
wktString is null or empty.
Example
// create a point with z, m
MapPoint point = MapPointBuilder.CreateMapPoint(100, 200, 300, 400, SpatialReferences.WebMercator);

// set the flags
WKTExportFlags wktExportFlags = WKTExportFlags.wktExportDefaults;
WKTImportFlags wktImportFlags = WKTImportFlags.wktImportDefaults;

// export and import
string wktString = GeometryEngine.Instance.ExportToWKT(wktExportFlags, point);
MapPoint importPoint = GeometryEngine.Instance.ImportFromWKT(wktImportFlags, wktString, SpatialReferences.WebMercator) as MapPoint;

double x = importPoint.X;       // x = 100
double y = importPoint.Y;       // y = 200
bool hasZ = importPoint.HasZ;   // hasZ = true
double z = importPoint.Z;       // z = 300
bool hasM = importPoint.HasM;   // hasM = true
double m = importPoint.M;       // m = 400

// export without z
WKTExportFlags exportFlagsNoZ = WKTExportFlags.wktExportStripZs;
wktString = GeometryEngine.Instance.ExportToWKT(exportFlagsNoZ, point);
importPoint = GeometryEngine.Instance.ImportFromWKT(wktImportFlags, wktString, SpatialReferences.WebMercator) as MapPoint;

x = importPoint.X;        // x = 100
y = importPoint.Y;        // y = 200
hasZ = importPoint.HasZ;  // hasZ = false
z = importPoint.Z;        // z = 0
hasM = importPoint.HasM;  // hasM = true
m = importPoint.M;        // m = 400

// export without m
WKTExportFlags exportFlagsNoM = WKTExportFlags.wktExportStripMs;
wktString = GeometryEngine.Instance.ExportToWKT(exportFlagsNoM, point);
importPoint = GeometryEngine.Instance.ImportFromWKT(wktImportFlags, wktString, SpatialReferences.WebMercator) as MapPoint;

x = importPoint.X;        // x = 100
y = importPoint.Y;        // y = 200
hasZ = importPoint.HasZ;  // hasZ = true
z = importPoint.Z;        // z = 300
hasM = importPoint.HasM;  // hasM = false
m = importPoint.M;        // m = Nan

// export without z, m
wktString = GeometryEngine.Instance.ExportToWKT(exportFlagsNoZ | exportFlagsNoM, point);
importPoint = GeometryEngine.Instance.ImportFromWKT(wktImportFlags, wktString, SpatialReferences.WebMercator) as MapPoint;

x = importPoint.X;        // x = 100
y = importPoint.Y;        // y = 200
hasZ = importPoint.HasZ;  // hasZ = false
z = importPoint.Z;        // z = 0
hasM = importPoint.HasM;  // hasM = false
m = importPoint.M;        // m = Nan
