TopoToRaster Tool Execute problem in ArcGIS

I am trying to execute TopoToRaster tool (ArcToolbox>3D Aanalyst Tool>Raster Interpolation>Topo To Raster) in arcGis 10.0 with .NET.

TopoToRaster Class Members

But get exceptions. My code is here :

private ESRI.ArcGIS.Analyst3DTools.TopoToRaster InitTool(out object beginningEnvironmentValue) { _gp = new Geoprocessor { OverwriteOutput = true, AddOutputsToMap = false }; beginningEnvironmentValue = _gp.GetEnvironmentValue("workspace"); _gp.SetEnvironmentValue("workspace", _workspace.PathName); _gp.SetEnvironmentValue("scratchWorkspace", _workspace.PathName); var topoToRaster = new ESRI.ArcGIS.Analyst3DTools.TopoToRaster { in_topo_features = _inputFeature,//new InputFeatureTopoToRaster() { FeatureLayer = _inputFeature.ToString(), Field = "HGL", Type = "CONTOUR" }, out_surface_raster = _outputRaster }; return topoToRaster; }

private readonly object _inputFeature; private readonly string _outputRaster;

public class InputFeatureTopoToRaster { public string FeatureLayer { get; set; } public string Field { get; set; } public string Type { get; set; } }

_inputFeature: is the input feature class path.

what is the problem of my input?? I have also tried with class of InputFeature

thanks..
