ArcGIS Pro 3.3 API Reference Guide
ArcGIS.Core.Geometry Namespace / IGeometryEngine Interface / ImportFromWKB Method
A combination of WkbImportFlags which determines how the geometry is imported.
The well-known binary buffer. The buffer must be OGC compliant.
The spatial reference of the output geometry.
Example

In This Topic
    ImportFromWKB Method (IGeometryEngine)
    In This Topic
    Creates a geometry based on the contents of the input well-known binary buffer.
    Syntax

    Parameters

    importFlags
    A combination of WkbImportFlags which determines how the geometry is imported.
    buffer
    The well-known binary buffer. The buffer must be OGC compliant.
    spatialReference
    The spatial reference of the output geometry.

    Return Value

    A Geometry that corresponds to the buffer.
    Example
    Import and Export Geometries to well-known Binary
    // create a polyline
    List<Coordinate2D> coords = new List<Coordinate2D>
    {
      new Coordinate2D(0, 0),
      new Coordinate2D(0, 1),
      new Coordinate2D(1, 1),
      new Coordinate2D(1, 0)
    };
    
    Polyline polyline = PolylineBuilderEx.CreatePolyline(
                coords, SpatialReferences.WGS84);
    
    WkbExportFlags wkbExportFlags = WkbExportFlags.WkbExportDefaults;
    WkbImportFlags wkbImportFlags = WkbImportFlags.WkbImportDefaults;
    
    // export and import
    byte[] buffer = GeometryEngine.Instance.ExportToWKB(wkbExportFlags, polyline);
    Geometry geometry = GeometryEngine.Instance.ImportFromWKB(
                   wkbImportFlags, buffer, SpatialReferences.WGS84);
    Polyline importPolyline = geometry as Polyline;
    
    
    // alternatively, determine the size for the buffer
    int bufferSize = GeometryEngine.Instance.GetWKBSize(wkbExportFlags, polyline);
    buffer = new byte[bufferSize];
    // export
    bufferSize = GeometryEngine.Instance.ExportToWKB(
                    wkbExportFlags, polyline, ref buffer);
    // import
    importPolyline = GeometryEngine.Instance.ImportFromWKB(
             wkbImportFlags, buffer, SpatialReferences.WGS84) as Polyline;
