问题:

I'm developing an asp.net mvc portal to manage GPS coordinates using localDB. My model is:

public class GpsCoordinateViewModel {     double Latitute { get; set; }     double Longitude { get; set; } }

the autogenerated adn related View to create a new GpsCoordinate is:

@{     ViewBag.Title = "Create"; }  Create
 @using (Html.BeginForm()) {     @Html.AntiForgeryToken()     @Html.ValidationSummary(true)       GpsCoordinateViewModel               @Html.LabelFor(model => model.Latitude)     
              @Html.EditorFor(model => model.Latitude)         @Html.ValidationMessageFor(model => model.Latitude)     
               @Html.LabelFor(model => model.Longitude)     
              @Html.EditorFor(model => model.Longitude)         @Html.ValidationMessageFor(model => model.Longitude)

}

     @Html.ActionLink("Back to List", "Index") 
  @section Scripts {     @Scripts.Render("~/bundles/jqueryval") }

the problem is that when I insert as Latitude: 41.213321 and Longitude: 12.123432 (eg), using breakpoin local values are: Latitude: 41213321 Longitude: 12123432. I need to use double because of location's accuracy, but how?

I also read this questions : How should I use EditorFor() in MVC for a currency/money type?

MVC3 - 3 decimal places on type double with leading zero

but the solutions didn't work for me. Any suggestion?

EDIT: My webconfig is:

回答1:

Might be caused by cultureinfo, some culture use , instead of . for decimal separator. try setting the following in web.config,

hope this helps

回答2:

Use Decimal Instead of Double as Your Data Type, and That might Help.

public class GpsCoordinateViewModel {     decimal Latitute { get; set; }     decimal Longitude { get; set; } }

回答3:

Well then, Use the String as a DataType and Parse it as a Decimal value Later from the Controller.
