c# - IIS 服务器上的 Double.ToString() 格式与开发不同

Question

我遇到了这个奇怪的问题。
在 Controller 中:

Model ses = new Model();
ses.Latitudine = ses.Sesizare.Locatie.HotSpotLocatie.First().HotSpotLatD;
ses.Longitudine= ses.Sesizare.Locatie.HotSpotLocatie.First().HotSpotLatD;

在模型中:

public class Model
{
    public double Latitudine {get; set;}
    public double Longitudine {get; set;}
}

在 View 中:

<h4><span class="glyphicon glyphicon-globe"></span> <a style="color:white" target='_blank' href='@("http://maps.google.com/maps?q=" + Model.Latitudine + "," + Model.Longitudine)'>Locatia:</a> </h4>

现在在 Visual Studio 中调试 View 呈现如下:

<h4><span class="glyphicon glyphicon-globe"></span> <a style="color:white" target="_blank" href="http://maps.google.com/maps?q=45.65933,25.561595">Locatia:</a> </h4>

http://maps.google.com/maps?q=45.65933,25.561595 (链接可用)

发布后我得到:

<h4><span class="glyphicon glyphicon-globe"></span> <a style="color:white" target="_blank" href="http://maps.google.com/maps?q=45,65933,25,561595">Locatia:</a> </h4>

http://maps.google.com/maps?q=45,65933,25,561595 (链接不可用)

开发和生产在同一台机器上。

在我的另一个 Controller 中:

 Latitude = t.LocatieGPS.Latitude.ToString();

这里的结果在生产和开发中都使用了 DOT。

这是生产 WebConfig:

<?xml version="1.0" encoding="utf-8"?>

Answer 1

这是机器文化造成的。您可能不想更改整个应用程序的区域性，因此只需指定您希望如何格式化小数。

InvariantCulture 使用点作为小数点分隔符:

@("http://maps.google.com/maps?q=" + Model.Latitudine.ToString(CultureInfo.InvariantCulture) + "," + Model.Longitudine.ToString(CultureInfo.InvariantCulture))
