Its not a valid json, you are missing the cast while sending the data from server to Client.

Thanks for your reply, Karthik
$.getjosn("/GetList",function(d){
//I want to export the data which GetList Return
})
GetList will return a jsonresult
return Json(new { total = count, rows = result.ToList() }, JsonRequestBehavior.AllowGet)

what is "result" type?

does the total and result count is same ?

july2008 7-Jul-16 2:08am

var result = from v in db.Admin_Menus
join r in db.Admin_Roles on v.F_Role equals r.F_RoleID
into T_Employee_Role
from dept in T_Employee_Role.DefaultIfEmpty()
select new
{
ID = v.F_MenuID,
Level = v.F_Level,
MenuName = v.F_MenuName,
MenuUrl = v.F_MenuUrl,
Sort = v.F_Sort,
Role = dept.F_RoleName
};
int count=result.Count()

Solution 2

just use this

C#

return Json(result.ToList(), JsonRequestBehavior.AllowGet);

JavaScript

alert(d.length);//to read the count

I can't use this
return Json(result.ToList(), JsonRequestBehavior.AllowGet);
because I'm using bootstrap-table to load the data,
the data is like this http://wenzhixin.net.cn/examples/bootstrap_table/data .
and what I want to do is read the data in the rows .

Karthik_Mahalingam 7-Jul-16 2:24am

use this
$.getJSON(url, function (d) {
var json = { count: d.length, rows: d };
debugger;
});

pass the json variable to the bootstrap table

great thanks

but the length for rows is 0, and the count is the right number, then how to get inner content in rows
thanks for your patience

count and rows will be equal.

does the GetList method returning rows?

Karthik_Mahalingam 7-Jul-16 3:18am

create a class

public class MyResult
{
public int total { get; set; }
public object rows { get; set; }
}

and use this

MyResult obj = new MyResult();
obj.total = result.Count();
obj.rows = result.ToList();
return Json(obj, JsonRequestBehavior.AllowGet);

now the json will in format which you need.

It looks there is a JSON syntax in your code.
A common use of JSON is to read data from a web server, and display the data in a web page, JSON data is written as name/value pairs. Curly brackets indicates objects and square for Array
here is basic syntax
