Ajax call returning a string describing an object instead of an object
I am running C # with MVC in ASP.NET and I have an ajax call that should return objects list
, but instead it just returns a string"System.Collections.Generic.List`1[Namespace.CustomObject]"
Obviously the data is returning it in javascript, and the return List<int>
doesn't change anything significant, so the object is not to blame. I made a mistake in my ajax call that I am missing, or do I need to use something other than list
?
My ajax call:
$.ajax({
type: 'POST',
url: url,
data: arrayOfInts
contentType: 'application/json',
datatype: 'json',
success: function (data) {
if (data.length) {
doThisIfDataReturned(data);
} else {
doThisIfNoDataReturned(productIds);
}
}
});
And the method it calls:
public List<CustomObject> MakeAList(int[] productIds)
{
//
// create objectList
//
return objectList; //debugger shows that list is correct here
}

In C #, you need to return a JSON object instead of a list. I've done things like this in the past:
public JsonResult myFunc()
{
..... code here .....
return Json(myList);
}
Edit: Sometimes it's nice to see exactly what is being sent back before it is sent. One way to achieve this is to assign the returned object to a variable and then return the variable.
public JsonResult myFunc()
{
..... code here .....
var x = Json(myList);
return x;
}
This does the same thing, but is a little easier to debug.
