DateTime property is set to null while deserializing

I have following json

 

{"Data":[{"MonthYear":"2017-03-01T00:00:00"},{"MonthYear":"2017-11-01T00:00:00"},{"MonthYear":"2017-12-01T00:00:00"}],"Filter":{"Page":{"PageSize":20,"PageIndex":1,"TotalRecords":3,"SortOrder":1,"OrderBy":null},"SearchText":null},"Message":{"MessageCode":200,"MessageType":1,"Message":"Success","MessageSource":"/abc"}}

 

when I deserialize that json using json.Net Library then the MonthYear property is set to null.

 

Please help me to resolve that issue.

 

Thanks.
