You will need to return the json as text/htmlsince IE does not know what to do with application/jsoncontents..
您将需要返回 json，text/html因为 IE 不知道如何处理application/json内容..
return Json(myObject, "text/html");
Not sure but it might work (and it would be more correct if it does) to use text/x-json
不确定，但它可能会工作（如果这样做会更正确）使用text/x-json
return Json(myObject, "text/x-json");

Even though this question is a few months old, I thought I'll add one more suggestion, just in case anyone else is using ASP.NET MVC 3 or 4and runs into this problem.
尽管这个问题已经有几个月的历史了，但我想我会再添加一个建议，以防万一其他人正在使用ASP.NET MVC 3 or 4并遇到这个问题。
In my experience, when IE attempts to download the Json response as a file all you have to do to correct the problem is to add a reference to jquery.unobtrusiveto your view.
根据我的经验，当 IE 尝试将 Json 响应下载为文件时，您只需添加jquery.unobtrusive对视图的引用即可纠正问题。
for example:
例如：
@Scripts.Render("~/Scripts/jquery.unobtrusive-ajax.min.js")
Once this is in place IE will no longer try to download the json response from a JsonResult controller action. No need to change the response type etc..
一旦到位，IE 将不再尝试从 JsonResult 控制器操作下载 json 响应。无需更改响应类型等。
