Javascript 如何在c#中动态地将多个纬度和经度传递给google距离矩阵api？

下面我使用了硬编码的多重lat-long

这取决于你如何获取/存储这些坐标。总的来说，这将有助于：

var origins=new double[]
{
新[]{24.7471299956982，46.5368152409792}，
新[]{24.5576972961426，46.8022346496582}，
新[]{24.9216365814209，46.7802574375}，
新[]{24.7977771759033，46.6214179992676}，
新[]{24.6342353820801，46.540504455664}，
新[]{24.869083404541，46.6235580444336}，
新[]{24.796724319458，46.7717247009277}，
};
var destinations=新的双精度[][]
{
新[]{24.7471295792982，46.5368152409792}，
新[]{24.5576972961426，46.8022346496582}，
新[]{24.9216365814209，46.780273475}，
新[]{24.7977771759033，46.6214179992676}，
新[]{24.6342353820801，46.540504455664}，
新[]{24.869083404541，46.6235580444336}，
新[]{24.796724319458，46.7717247009277}，
};
字符串格式（双[][]跳线）=>string.Join（“|”，跳线。选择（c=>string.Join（“，”，c））；
变量输出=$”https://maps.googleapis.com/maps/api/distancematrix/xml" +
$“？源={format（origins）}”+
$“&destinations={format（destinations）}”+
$“&出发时间=1621784369”+
$“&callback=InitializeMap”+
$“&libraries=places”+
$“&v=每周”；
控制台写入线（输出）；

@umberto pertov-上面的代码将给出c=>string.join（'，'，c）处的转换错误。我测试了它，它对我有效。。你能复制粘贴那个“转换错误”的全部文本吗？这样我们就可以了解失败的原因了？
