The inner exception is:
{"true,false is not a valid value for Boolean."}

So Please suggest me how to resolve it..

When you are using a checkbox on your view in MVC then that checkbox also add a extra hidden filed for same name and when you go submit then you will get hidden filed value of check box.

Now check box and hidden filed have same name then a single request variable has both values comma separate like "true,false" but first value always for checkbox and second value for hidden filed so you can split this and get check box value.

C#

[HttpPost]
      public ActionResult Index(FormCollection form)
      {
          bool MyBoolValue= Convert.ToBoolean(form["MyBoolValue"].Split(',')[0]);
          return View();
      }

other way

View is

HTML

@Html.CheckBoxFor(x => x.MyBoolValue, Model.MyBoolValue)

C#

[HttpPost]
      public ActionResult Index(Modal model)
      {
          bool MyBoolValue= Convert.ToBoolean(model.MyBoolValue);
          return View();
      }

Solution 2

Use Convert.ToBoolean to convert the values to boolean.
Then do the comparison.
