/system.web.extensions 还必须重写JsonResult这个类 ConfigurableJsonResult public class ConfigurableJsonResult : JsonResult{public override void ExecuteResult(ControllerContext context){if (context null){throw new ArgumentNullException(context);}if (JsonRequestBehavior JsonRequestBehavior.DenyGet String.Equals(context.HttpContext.Request.HttpMethod, GET, StringComparison.OrdinalIgnoreCase)){throw new InvalidOperationException(This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.);}HttpResponseBase response context.HttpContext.Response;if (!String.IsNullOrEmpty(ContentType)){response.ContentType ContentType;}else{response.ContentType application/json;}if (ContentEncoding ! null){response.ContentEncoding ContentEncoding;}if (Data ! null){JavaScriptSerializer serializer new JavaScriptSerializer();ScriptingJsonSerializationSection section ConfigurationManager.GetSection(system.web.extensions/scripting/webServices/jsonSerialization) as ScriptingJsonSerializationSection;if (section ! null){serializer.MaxJsonLength section.MaxJsonLength;serializer.RecursionLimit section.RecursionLimit;}response.Write(serializer.Serialize(Data));}}} 测试后可以正常使用。 参考 http://www.cnblogs.com/shenba/archive/2012/02/03/2337050.html http://weblogs.asp.net/rashid/archive/2009/03/23/submitting-my-first-bug-after-asp-net-mvc-1-0-rtm-release.aspx 转载于:https://www.cnblogs.com/sherlock99/p/3659759.html
