ASP.NET MVC 表单和双字段

Question

我正在开发一个 asp.net mvc 门户来使用 localDB 管理 GPS 坐标。我的模型是:

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

创建新 GpsCoordinate 的自动生成的 adn 相关 View 是:

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>
@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

<fieldset>
    <legend>GpsCoordinateViewModel</legend>

    <div class="editor-label">
        @Html.LabelFor(model => model.Latitude)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Latitude)
        @Html.ValidationMessageFor(model => model.Latitude)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Longitude)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Longitude)
        @Html.ValidationMessageFor(model => model.Longitude)
    </div>
    <p>
        <input type="submit" value="Create" />
    </p>
</fieldset>

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

问题是，当我插入纬度:41.213321 和经度:12.123432(例如)时，使用断点的本地值是:纬度:41213321 经度:12123432。由于位置的准确性，我需要使用 double，但如何使用？

我也读过这个问题: How should I use EditorFor() in MVC for a currency/money type?

MVC3 - 3 decimal places on type double with leading zero

但解决方案对我不起作用。有什么建议吗？

编辑:我的网络配置是:

<system.web>
<httpHandlers>
  <add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/>
</httpHandlers>

<!--
    Enabling request validation in view pages would cause validation to occur
    after the input has already been processed by the controller. By default
    MVC performs request validation before a controller processes the input.
    To change this behavior apply the ValidateInputAttribute to a
    controller or action.
-->
<pages
    validateRequest="false"

  </controls>
</pages>
<globalization culture="en-US" uiCulture="en-US" />

Answer 1

可能是cultureinfo引起的，一些culture使用,代替.作为小数点分隔符。尝试在 web.config 中设置以下内容，

<system.web>
    <globalization culture="en-US" uiCulture="en-US" />
</system.web>

希望对你有帮助
