您的Json是正确的，您可以使用JSONLint进行验证。我还尝试使用JQuery parseJSON 方法解析它并且它有效。

代码示例

var _result =
   '{"MyLearningList": [{"LearningId": 26,"Curriculum": "Administrative Law","CurriculumURL": null, "TrainingStatus": "InProgress","StartDate": "10/15/2012","EndDate": "10/15/2013"},{"LearningId": 2,"Curriculum": "Architecture","CurriculumURL": null,"TrainingStatus": "InProgress","StartDate": "10/15/2012","EndDate": "11/15/2013"},{"LearningId": 11,"Curriculum": "Audit","CurriculumURL": null,"TrainingStatus": "InProgress","StartDate": "10/15/2012","EndDate": "10/15/2013"},{"LearningId": 21,"Curriculum": "Automobile Engg.","CurriculumURL": null,"TrainingStatus": "InProgress","StartDate": "10/15/2012","EndDate": "10/15/2013"},{"LearningId": 32,"Curriculum": "B. A. M. S. (Bachelor of Ayurvedic Medicine and Surgery)","CurriculumURL": null,"TrainingStatus": "InProgress","StartDate": "10/15/2012","EndDate": "10/5/2013"}],"PageSize": 5,"CurrentPageNumber": 1,"TotalRecordCount": 39,"TotalPageCount": 8,"NextPageUrl": "sharepoint02:50000/LMSRest.svc/rest/GetDemoOAuthPlan?LMSUsername=bfolmer&PageNumber=2&PageSize=5&SortColumn=Curriculum&SortDirection=True","PreviousPageUrl": ""}';

var obj = $.parseJSON(_result);

alert(obj.PageSize);
alert(obj.NextPageUrl);

使用您的JSON here

的工作示例
