The parameter conversion from type 'System.String' to type '

The error is saying that, when you are assigning string to Model.Zone then it is generating error. Because model.zone is of different type. But if you want to assign then do typecasting otherwise set the datatype of both as same. Thanks.

When doing typecasting, do check the string is not converting it into your model type..
