    copied!<p>Is there a difference in creating the object inside and outside for loop..I am not sure but i am experiencing an error with the oCategoryDefinition being declared outside of forloop :</p> <blockquote> <p>Invalid cast from 'System.Int32' to 'xxx.CategoryDefinition' at System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider) at System.Int32.System.IConvertible.ToType(Type type, IFormatProvider provider) at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) at Service.AddFeatureValues(VINDescription vinDescription, VehicleDescription vehicleDescription)</p> </blockquote> <p>></p> <pre><code> for (int i = 0; i &lt; listLength; i++) { CategoryDefinition oCategoryDefinition = (CategoryDefinition)Convert.ChangeType (vehicleDescription.genericEquipment[i].Item, typeof(CategoryDefinition)); vinDescription.StandardFeature.Add(oCategoryDefinition.category.Value); } </code></pre> <p>AND</p> <pre><code>CategoryDefinition oCategoryDefinition = new CategoryDefinition(); for (int i = 0; i &lt; listLength; i++) { oCategoryDefinition = (CategoryDefinition)Convert.ChangeType (vehicleDescription.genericEquipment[i].Item, typeof(CategoryDefinition)); vinDescription.StandardFeature.Add(oCategoryDefinition.category.Value); } </code></pre> <p><strong>EDIT</strong></p> <p>To add one angle to the issue : Below is the method which is firing the <strong>above error</strong>: </p> <pre><code> private void AddFeatureValues(VINDescription vinDescription, VehicleDescription vehicleDescription) { GenericEquipment[] genericEquipList = null; //To add standard features to the vehicle details list.
