保持来自ajax的地理坐标

晚上好， j试图从用户检索数据，但问题iç，我无法处理因为“，”经度和纬度的坐标，我不知道如何处理这些给，我试图与parsefloat但是没有结果，谢谢代码控制器动作：保持来自ajax的地理坐标

public ActionResult GetNeaarByLocations(string CurrentLat, string CurrentLng) 
    { 
     using (GeolocationTestEntities context = new GeolocationTestEntities()) 
     { 
      var CurrentLocation = DbGeography.FromText("POINT(" + CurrentLat + " " + CurrentLng + ")"); 
      //var CurrentLocation = DbGeography.FromText("POINT(36,806494799999996 10,181531600000001)"); 
      var places = (from u in context.schoolinfo orderby u.Location.Distance(CurrentLocation) 
          select u).Take(4).Select(x=>new schoollinfo(){ Name = x.name ,Lat = x.Location.Latitude, Lng = x.Location.Longitude,Distance = x.Location.Distance(CurrentLocation)}); 
      var nearschools = places.ToList(); 
      return Json(nearschools , JsonRequestBehavior.AllowGet); 
     } 
    }

，这是代码的Ajax：

jQuery.ajax({ 
        cache: false, 
        type: "POST", 
        url: "@Url.Action("GetNeaarByLocations")", 
        dataType: "json", 
       contentType: "application/json;charset=utf-8", 
       data: JSON.stringify({ CurrentLng:currentLatLng.longitude, CurrentLat: currentLatLng.latitude }), 
       success: function (data) { 
        if (data != undefined) { 
         $.each(data, function (i, item) { 
          addMarker(item["lat"], item["lng"], "Click to get directions"); 

         }) 
        } 
       }, 
       failure: function (errMsg) { 
        alert(errMsg); 
       } 

      });

感谢所有。

我们需要LNG转换&兰特翻番

var currentLatLng = position.coords; 
       var Lat = currentLatLng.latitude; 
       var Lng = currentLatLng.longitude; 
       var LatDouble = parseFloat(Lat); 
       var LngDouble = parseFloat(Lng);

对Ajax是删除ATT字符串化

data: JSON({ CurrentLng:LngDouble , CurrentLat: LatDouble }),
