i finally find the solution
i write the code to help anyone want do this conversion 

this is the code (using c#) to convert layer to KML:

//convert layer to kml
                ESRI.ArcGIS.Geoprocessor.Geoprocessor GP = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
                GP.AddToolbox(@"C:\Program Files\ArcGIS\ArcToolbox\Toolboxes\3D Analyst Tools.tbx");

                GP.SetEnvironmentValue("workspace", @"C:\Maps\Maps");

                GP.OverwriteOutput = true;

                IVariantArray parameters = new VarArrayClass();
               // assign  parameters       
                parameters.Add(mylayer);
                parameters.Add(@"C:\Maps\Maps\city.kmz");
                parameters.Add(1);

                GP.Execute("LayerToKML_3D", parameters, null);
