c# - 当我找不到逗号时如何将逗号更改为点

Question

对我来说这有点奇怪，因为我试图将其输入到我的应用程序中:

"https://embed.windy.com/embed2.html?lat=37.751&lon=-0.854&detailLat=36.751&detailLon=-0.854&width=650&height=450&zoom=10&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1";

这非常有效。但是，我想插入我自己的纬度和经度，并使用此代码来执行此操作:

url = "https://embed.windy.com/embed2.html?lat=";
    url += latitude;
    url += "&lon=";
    url += longitude;
    url += "&detailLat=";
    url += latitude;
    url += "&detailLon=";
    url += longitude;
    url += "&width=650&height=450";
    url += "&zoom=10";
    url += "&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1";

我是这样做的，因为我试图找出问题所在。

当我打印网址时，我得到:

https://embed.windy.com/embed2.html?lat=37.752&lon=-0.854&detailLat=37.752&detailLon=-0.854&width=650&height=450&zoom=10&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1

在此打印中，我在纬度和经度中没有逗号:

lat=37.752
lon=-0.854
detailLat=37.752
detailLon=-0.854

到目前为止一切都很好。但是，当我通过 Xcode 上传应用程序时，我可以在 Xcode 日志中看到以下内容:

https://embed.windy.com/embed2.html?lat=37,752&lon=-0,854&detailLat=37,752&detailLon=-0,854&width=650&height=450&zoom=10&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1

这里是逗号表面:

lat=37,752
lon=-0,854
detailLat=37,752
detailLon=-0,854

这是我用来设置纬度和经度的基本代码:

latitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.x, 3).ToString();
longitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.y, 3).ToString();
//latitude = Utility.setup_List[0].freqSetLocation1.x.ToString();
//longitude = Utility.setup_List[0].freqSetLocation1.ToString();

我尝试在统一输出中找到逗号，但没有成功。

当我对纬度和经度进行硬编码时，它再次完美运行，但当我按照上面的方式添加纬度和经度时，Xcode 会生成逗号。

这是完整的代码:

public class Radar : MonoBehaviour
{
public GameObject pnl_Background;
public TMP_Text txt_TitleRadar;
public Button btn_RadarGoBack;
public TMP_Text txt_RadarInfo;
private string latitude;
private string longitude;

public WellWebView WebView;

    SetColors();

    if (Utility.setup_List[0].isLocations)
    {
        switch (Utility.processLocationBtnNr)
        {
            case 1:
                txt_RadarInfo.text = Utility.setup_List[0].locationName1 + ", " + Utility.setup_List[0].countryName1;
                latitude = Math.Round((decimal)Utility.setup_List[0].setLocation1.x, 3).ToString();
                longitude = Math.Round((decimal)Utility.setup_List[0].setLocation1.y, 3).ToString();
                break;
            case 2:
                txt_RadarInfo.text = Utility.setup_List[0].locationName2 + ", " + Utility.setup_List[0].countryName2;
                latitude = Math.Round((decimal)Utility.setup_List[0].setLocation2.x, 3).ToString();
                longitude = Math.Round((decimal)Utility.setup_List[0].setLocation2.y, 3).ToString();
                break;

                latitude = Math.Round((decimal)Utility.setup_List[0].setLocation3.x, 3).ToString();
                longitude = Math.Round((decimal)Utility.setup_List[0].setLocation3.y, 3).ToString();
                break;
            case 4:
                txt_RadarInfo.text = Utility.setup_List[0].locationName4 + ", " + Utility.setup_List[0].countryName4;
                latitude = Math.Round((decimal)Utility.setup_List[0].setLocation4.x, 3).ToString();
                longitude = Math.Round((decimal)Utility.setup_List[0].setLocation4.y, 3).ToString();
                break;
        }
    }
    else
    {
        txt_RadarInfo.text = Utility.setup_List[0].freqLocationName1 + ", " + Utility.setup_List[0].freqCountry;
        latitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.x, 3).ToString();
        longitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.y, 3).ToString();
        //latitude = Utility.setup_List[0].freqSetLocation1.x.ToString();
        //longitude = Utility.setup_List[0].freqSetLocation1.ToString();
    }

    //url = "https://embed.windy.com/embed2.html?lat=" + latitude + "&lon=" + longitude + "&detailLat=" + latitude + "&detailLon=" + longitude + "&width=800&height=1224&zoom=8&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1";

    url = "https://embed.windy.com/embed2.html?lat=";
    url += latitude;
    url += "&lon=";
    url += longitude;
    url += "&detailLat=";
    url += latitude;
    url += "&detailLon=";
    url += longitude;
    url += "&width=650&height=450";
    url += "&zoom=10";
    url += "&level=surface&overlay=radar&product=radar&menu=&message=&marker=&calendar=now&pressure=&type=map&location=coordinates&detail=&metricWind=default&metricTemp=default&radarRange=-1";

    print(url);

    //print("#" + url.IndexOf(','));

    StartRadar();
}

void StartRadar()
{
    WellWebView.SetAllowJavaScript(true);
    WellWebView.SetJavaScriptCanOpenWindowsAutomatically(true);
    WebView = WellWebView.CreateWebView();

    WebView.OnFinishedInit += (RaisedWebView) =>
    {
        // The web view is fully initialized, and you can call the web view methods
        WebView.FullScreen = false;
        WebView.SetSupportMultipleWindows(true);
        WebView.SetTargetRect(image);
        WebView.Android.SetUseWideViewPort(true);
        WebView.Android.SetLoadWithOverviewMode(true);
        WebView.IOS.AllowBackForwardNavigationGestures(true);
        WebView.LoadUrl(url);
        WebView.Show();
    };
    WebView.Init();
}

void SetColors()
{
    pnl_Background.GetComponent<Image>().color = Utility.backgroundColor;
    txt_TitleRadar.color = Utility.foregroundColor;
    txt_RadarInfo.color = Utility.foregroundColor;
    btn_RadarGoBack.image.color = Utility.foregroundColor;
}


public void BTN_RadarGoBack()
{
    WebView.StopLoading();
    WebView.Destroy();
    SceneManager.LoadScene("WeatherList");
}

}

顺便说一句，我使用 Unity 资源 WellWebView 来显示雷达图。

将 CultureInfo.InvariantCulture 传递给您的 .ToString() 方法。

latitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.x, 3).ToString(CultureInfo.InvariantCulture);
longitude = Math.Round((decimal)Utility.setup_List[0].freqSetLocation1.y, 3).ToString(CultureInfo.InvariantCulture);
