javascript - 在 asp.net mvc 4 中使用动态关键字时出错

Question

当我在 mvc 4 中的服务器端操作方法上将参数接受为动态参数时，出现了这个很长的错误。

{"Message":"An error has occurred.","ExceptionMessage":"'Newtonsoft.Json.Linq.JObject' does not contain a definition for 'TournamentId'","ExceptionType":"Microsoft.CSharp.RuntimeBinder.RuntimeBinderException","StackTrace":" at CallSite.Target(Closure , CallSite , Object )\r\n at System.Dynamic.UpdateDelegates.UpdateAndExecute1[T0,TRet](CallSite site, T0 arg0)\r\n at ManagerDeTorneos.Web.Controllers.TournamentDateController.Create(Object data) in F:\Prince\Projects\Juan\trunk\ManagerDeTorneos.Web\Controllers\TournamentDateController.cs:line 133\r\n at lambda_method(Closure , Object , Object[] )\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c_DisplayClass13.b_c(Object instance, Object[] methodParameters)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

[HttpPost]
public HttpResponseMessage AddMatch(dynamic data)
{
    int tournamentDateId = (int)data.TournamentDateId.Value;
    var tournamentDate = Catalog.TournamentDateRepository.GetById(tournamentDateId);
    if (tournamentDate == null)
    {
        throw ExceptionHelper.NotFound("Fecha no encontrada!");
    }

在上述方法中，数据包含从ajax调用发送的tournamentId，格式为JSON.Stringify({'TournamentId':'5'})。

谁能告诉我错误的原因是什么？我什至还替换了Newtonsoft.Json的dll

你是对的，但我通过从 GAC 中删除该 dll 解决了我的问题。可能在 GAC 中它使用的是旧程序集
