Interpolate surface C#

Hello!

I'm trying interpolate surface using point shapefile, but ArcMap crashed on interpolation. I checked and able to do it using predefined Arctoolbox scripts, so data is ok.

I use ArcGIS 10.1 SP1, Spatial Extension, MS Visual Studio 2012, .Net Framework 4.

 

Does anyone can help in it?

 

public void InterpolateTest()
        {
            IFeatureClass fcClass01 = default(IFeatureClass);
            fcClass01 = GetFeatureClass(); // see below
         

// Create FeatureClassDescriptor using a value field.
            IFeatureClassDescriptor fcDescr = default(IFeatureClassDescriptor);
            fcDescr = new FeatureClassDescriptor() as IFeatureClassDescriptor;
            fcDescr.Create(fcClass01, null, "gdsA");
         

// Create Input geodataset
            IGeoDataset gd = fcClass01 as IGeoDataset;

// Create Output geodataset      

            IRaster rasOut = default(IRaster);


            IInterpolationOp2 interpOp = default(IInterpolationOp2);
            interpOp = new RasterInterpolationOp() as IInterpolationOp2;
        

  //try to interpolate - crash on this line
            rasOut = (IRaster)interpOp.NaturalNeighbor(gd);

        }

 

 

 

public ESRI.ArcGIS.Geodatabase.IFeatureClass GetFeatureClass()
        {

                    ESRI.ArcGIS.Geodatabase.IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactory();
   
                    String string_RasterWorkspace = "C:\\temp\\";
                    String string_ShapefileName = "dis.shp";

                    ESRI.ArcGIS.Geodatabase.IWorkspace workspace = workspaceFactory.OpenFromFile(string_RasterWorkspace, 0);
                    ESRI.ArcGIS.Geodatabase.IFeatureWorkspace featureWorkspace = (ESRI.ArcGIS.Geodatabase.IFeatureWorkspace)workspace; // Explict Cast
                    ESRI.ArcGIS.Geodatabase.IFeatureClass featureClass = featureWorkspace.OpenFeatureClass(string_ShapefileName);

                    FeatureClass fc = featureClass as FeatureClass;
                    return featureClass;
        }
